Today we will take a closer look at the main types of circular saws. Let's define reasonable criteria for choosing a specific model. We will draw conclusions for recommendations based on the experience of practicing builders and employees of service centers. Join us.

The electric circular saw (in the popular way "circular", "parquet") appeared in the twenties of the last century. As usual, several "organizations" have worked. At first, a radial-cantilever type of wood cutting machine was developed (Raymond DeWolt), a little later, under the Skilsaw brand, manual models (Salivan and Mitchell) began to be produced. There were also separate patents for side and integrated saws to A. Emmons and A. Steele, respectively. Well, the AEG company helped to "ground" the invention and promote it to the masses, the engineers of which were the first to connect the instrument to the general 220 volt network. Nowadays, the circular saw has reached perfection, the set of options and auxiliary systems for it has not changed for a very long time, not to mention the design features. It's just that everyone is slowly pulling up to the premium class.

Circulars are considered to be one of the most technically challenging tools, even if you ignore the fact that they can have a full set of electronic bells and whistles available. The fact is that here it is necessary to constructively provide unprecedented safety measures (like all disk machines, "parquet floors" can be very traumatic), as well as to implement the high accuracy of many spatial mechanical settings. Self-repair of the circular is considered a risky enterprise due to the difficulty of restoring the correct factory settings.

The main purpose of a circular saw is to perform longitudinal cutting of wood and its derivatives (OSB, chipboard, fiberboard, MDF, plywood), because this tool perfectly keeps the line, a jigsaw is no comparison here. Naturally, cross-cutting for circulars will not be a problem either. But it would be strange if a modern cutting unit were not sharpened to work on other materials. Indeed, using various types of discs, and in some cases changing the shaft rotation frequency, it is possible to cut laminated workpieces, gypsum fiber board, plastic of various densities, multilayer materials (sandwiches), slate, plexiglass. In a word, almost all sheet panels are perfectly cut, including at an angle to the main plane. The only thing that is too tough for circulars is dense mineral materials (concrete, brick, plaster). True, some units can be equipped with a diamond disc and have a water supply, structurally these are full-fledged circulars (Makita 4101RH). There is still one iron "but" - a circular saw cannot cut along a curved line.

What is a circular for metal

We should also highlight circular saws for metal work. Although they are positioned in the market in this way, they are essentially multifunctional. It's more about the characteristics of the standard wheel, which comes in the basic configuration (this is not an abrasive, it is a hard-alloy toothed multi-purpose disc). Such units are easy to deal with pipes, sheet metal, complex profiles, sheet steel and stainless steel (Makita 4131). It is very simple to talk with both steel and soft non-ferrous alloys (based on copper, aluminum).

But what about the angle grinder? Compared with grinders equipped with a cutting disc, we have the following:

The performance is much higher.
The operator is relieved as the machine rests on the sole.
Reduces noise and vibration.
Possible bevel work.
There are no sparks, the workpiece hardly heats up and does not "burn".
Increased safety (the rig is almost completely hidden and not subject to tearing).
The service life of a carbide disc is about 100 times that of an abrasive.
The cutting price is the lowest (only the guillotine is cheaper and faster).
There is no release of mineral dust into the air, as from a stone tool.
The cut is very high quality, without burrs.

Our masters have just tried this device, and in Europe and the USA such machines are used with might and main, quite naturally, with such and such advantages. For example, the EVOLUTION 230 XTREME model cuts sheet steel (class A-3) with a thickness of 12 mm, profiles / pipes with a wall of 4 mm, and, of course, everything else (wood, polymers).

Plunge-cut circular saw

Another class of circulars is the plunge-cut saw. It is designed to plunge into the workpiece anywhere, not just from the edge. The lower automatic cover is completely absent here, and the disc is located above the base plate and is lowered only when the start button is pressed. Naturally, the cutting depth is adjustable, often in a range of millimeters (DWS520K).

The submersible mechanism (something similar is implemented in the wall chasers) allows for local repair of the roof, dismantling several selective floorboards, and cutting an opening in the tabletop. Grooves, slots, gutters can be made without much difficulty. For correct work with sandwiches and laminated materials - the top layer can be cut with a preliminary cut to an incomplete depth of the workpiece, thereby eliminating the risk of chips. All this is done not only perpendicular to the plane of the part, but also under a variable slope.

Cordless circular saw

More recently, such units seemed to us to be sheer fantasy. But as time goes on, wireless technologies are reaching a new level. Batteries have become so capacious, special motors are so economical, and chargers are fast, that even for such a powerful tool as a circular, the developers managed to organize an uninterrupted power supply. We take two modern batteries and a half-hour charge - that's it, there will be no problems with energy (Makita BSS 610 RFE). It's even easier if your circular saw is equipped with a unified battery from the same manufacturer as the rest of your tools. The power characteristics (output power, torque) of wireless circulars are in no way inferior to those of similar networked machines - Bosch GKS 18 V-Li (cutting depth 51 mm). Well, as for mobility and ergonomics, here they are beyond any competition, especially roofers-operatives who work at height love them.

Main selection criteria

Power, speed, disc diameter, cutting depth

The diameter of the cutting disc (outer, not the size of the bore) - it can be said without exaggeration that this is the main parameter of the circular. Based on it, manufacturers are forced to compose a specific model. The larger the disc, the more powerful the motor must be in order to spin it up to the required speed, the more torque is required to maintain this speed and there is no jamming, the more technologically advanced the stabilization system should be, so that there is no beating, vibration and noise, the heavier , overall, the saw will be more expensive. But on the other hand, large tooling allows you to saw more massive workpieces, thicker material.

However, it is not enough just to pay attention to the size of the circle, it is much more important to have an accurate idea of \u200b\u200bthe maximum cutting depth. Developers almost always indicate these parameters in their passports, both for perpendicular and beveled cut. There is some conditional separation:

Light class (40-50 mm) - sheet materials, work "on site".
The middle class (50-65 mm) is the most common and universal.
Heavy class (65-140 mm) - these are massive, purely professional machines.

The convention is that many companies issue their own special classification (Makitov people, for example, do not release babies at all and move a little forward in this matter). It turns out that we, ordinary users, can only listen to our needs, choose a priority in the ratio "maneuverability / versatility / strength", based on the specifics of the proposed work. For example, Hitachi C13U (weight 13 kg, disc 335 mm, 2000 watts) and Hitachi C6MFA (weight 3.4 kg, disc 165 mm, 1010 watts). The ratio of the straight cut depth for these models is 128 mm to 57 mm, respectively.

Left: Hitachi C13U, right: Hitachi C6MFA

I would also like to note that in case of emergency, you can cut a very bulky part by making a cut from both sides (yes, for correct operation, the disc does not have to go through the workpiece).

What else gives a power reserve? If there is a need to compare two circulars with the same depth, then a stronger motor of one of them will provide better frequency stability, longer continuous operation, and will allow faster cutting of denser material. Watts under the hood are traditionally related to the diameter of the rig and, again, conditionally, the units are credited to one of the three corresponding classes:

Up to 800 watts.
800 to 1200 watts.
More than 1200 W (for example, Hitachi C9U2 - 2 kW, Makita 5143R - 2.2 kW).

Disk rotation speed - what does it give, besides the speed itself? There are two main nuances. First, the faster the shaft moves, the cleaner the cut is (however, the cleanliness depends more on the type of disc - the number and shape of teeth). Second, high speed is the opposite of torque. Third, high speed is high temperature and some plastics can melt during sawing. If the frequency has become a stumbling block (read "choice"), then you need to compare saws with the same diameter of the cutting disc. Better yet, find a model with an idle speed control.

Electronics on guard

Advanced circulars are stuffed with electronic systems to the eyeballs. This is quite predictable, since this tool is powerful and dangerous - the user needs help so that the mission is not impossible. If there is a financial opportunity, do not give up additional options, for performance and safety there are no unnecessary trifles.

For the benefit of the correct speed mode, the system for maintaining a constant spindle speed under load, the so-called constant electronics (DeWalt DWS520K), works. A special controller constantly reads the speed and when there is a local drop in speed (for example, when the feed is accelerated or when the tooling hits the compacted area of \u200b\u200bthe material), it is stabilized by an automatic increase in the output power. The probability of a disc jam is reduced to almost zero, but the quality of the cut only improves. Obviously, this requires a certain power reserve (this is the prerogative of relatively large machines). Another point is the idle speed adjustment, preset. It is needed for manual selection of process parameters for materials with different physical characteristics (Metabo KSE 68 Plus). Not all models can boast of this option. And, by the way, the possibility of presetting is not a prerequisite for the presence of constant electronics, the only available frequency can also be stabilized.

In order not to overload the network when the tool is turned on, since the starting currents, albeit in a short period of time, significantly exceed their rating - almost all more or less powerful circulars have a soft start system. The rig does not accelerate immediately, which eliminates the jerk of the tool and protects the gearbox parts from unnecessary shock loads, the unit lives much longer ("Fiolent" PD 3-70E).

If the operator is in a hurry to finish what he started and does not listen to the "well-being" of the circular saw, then the overload protection system will receive a signal from overheated motor windings or react to a sharp drop in power consumption and turn off the power, keeping the expensive tool working.

The electrodynamic brake stops the disc abruptly after the release of the start button (AEG BKS 18). The system is designed to protect the operator from possible injury, the part from damage, and the machine from kickback.

Mechanical features

If the rig is deafly jammed, the motor can fail very quickly, there is a possibility of a kickback. To protect against such a nuisance, a slip clutch is used. The working shaft of the motor will continue to rotate even if the disc is stationary. Don't worry, the system won't work unnecessarily.

Protection against accidental activation is realized by installing an additional button in the area of \u200b\u200bthe main handle. To apply power to the motor, you must press it simultaneously with the start key (Skil 5064AA). It is, perhaps, impossible to make such a chord unintentionally, especially since the "fuse" is usually sunk into the head. Often (for other tools) this button allows you to lock the trigger on, this will not work here - the toothed disk must always be under control.

For the convenience of replacing the disc, the spindle can be locked with a button or a lever, in some models literally in any position (you do not need to scroll to look for the gripping point - Bosch GKS 65 CE Professional). If there is no lock, you have to wield two keys at once. The nut itself can be tightened with a wrench / screwdriver, or it can be made in a “toolless” version - quick-clamping.

A lot of the functionality of the circular depends on its base plate. Note that it is on it that all mechanical adjustments and fasteners for auxiliary elements are installed. Traditionally, platforms made by casting light alloys are considered to be of higher quality. They unambiguously indicate the professional class of the instrument, as they keep their geometry well ("Interskol" DP-235 / 2000M). However, do not discount thick stamped steel pads. They are more resistant to shock loads (do not crack from an accidental impact), have a lower impact on the price of the product, and are also used in tools for professionals (Bosch GKS 65 CE Professional).

"Interskol" DP-235 / 2000M

An important point is the adjustment of the inclined cut. Angle sawing is realized precisely by changing the position of the platform relative to the entire upper part and the disc in particular. Usually the tilt is set at different angles: 30 °, 45 °, and in some machines it is extended to 50-55 °. The mechanism for setting the cutting depth is also located here. As a rule, this is all made in the form of grooves in the shape of a quarter circle (in some cases graduated) and rods with wing / lever clamps. The main advantage of quality control elements is speed, reliability and accuracy of fixing (Kress 1400 HKS). Backlashes are extremely unwanted guests here.

Another advantage of the well thought-out platform is the ability to set the saw in a stationary position. This refers to the option of creating a machine without using a special table. This moment will be relevant for all machines, but even more so for especially powerful and heavy ones.

To perform a high-quality straight cut, circular saws are already equipped with a parallel stop as standard, by the way, it can also be light-alloy. However, the most accurate sawing work can be achieved using a guide bar. The tire is bought separately (often they come from other manufacturers), but the sole must have a special groove. If it is necessary to work "by hand" on the markings, you need to control the line; for this, a special slotted opening is made in front of the base plate. An interesting option is implemented in the EVOLUTION 180 XTREME saw, where a laser line builder is built into the handle, during operation you just need to combine it with the marking.

A compulsory accessory for the circular saw is a spring-loaded cover that completely hides the blade and releases it only when starting cutting (you need a stop on the workpiece). The cover should slide easily and always return to its original position. To prevent the disc from being squeezed from the sides by the already cut material and not stopping, a “riving knife” is used in the design.

Ergonomics and something else

The circular is a manual tool, therefore, when choosing, special attention should be paid to the overall ergonomics of the product. Interestingly, some manufacturers even make a left-handed tool with a mirrored layout.

The most important role in the comfort of any circular is assigned to the shape and location of the handles. Obviously, each user will have different requirements. Most of the questions are raised by the front handle, which is most often straight, located perpendicular to the plane of movement of the saw blade. This design is good if you work from yourself forward, but most often the tool is guided from the side - therefore, most craftsmen prefer the mushroom version, which is easily held in any position (DeWalt D23620). Someone may be more suitable for the bracket design (DeWalt D23650K).

Give preference to models with rubberized handles, they help to securely hold and control the tool during operation.

It will not be superfluous to hold a few circulars in your hands before buying, most likely, a lot will become clear to you regarding the weight distribution of specific cars and their balance. Be sure to do this if you plan to do a lot of fieldwork.

Evaluate the visibility of the working area, the specific design features of the circular saw have a very serious effect on this circumstance. It is also important how efficiently sawdust is removed from the disc. Here, surface blowing is used (directed from the operator), a branch pipe is integrated for connecting an industrial vacuum cleaner and connecting a bag. There are options with a dust container.

Take a look at how the power cord entry point is executed. Unfortunately, users very often cut the power cable, so it is better if it is directed straight back, and the inlet sleeve is as long and rigid as possible. Maximum freedom and safety will be provided by a long power cord - 4 meters is no longer uncommon for professional models. Otherwise, you will have to regularly fight with the extension block.

Sooner or later, the circular saw will require replacement of the carbon brushes, otherwise the engine anchor is at risk. Therefore, it makes sense to "monitor" this node as well. Well, if there is a separate window for quick access to the brushes, then you don't have to disassemble the case, or go to the service for this if the device is under warranty. An excellent option is self-disconnecting brushes: the graphite is worn out - the chain is broken (Sparky TK 70). The next nuance lies in the indication of the status of the brushes, this is a very useful gadget for the traditional brush assembly.

Most likely, under load you will not be allowed to test the saw, but if the seller allows, plug in the saw and run it at idle speed, listen to the noise and vibration levels. Evaluate how strong the air flow is generated by the tool - this largely determines the efficiency of cooling the motor and the quality of cleaning the working area from debris.

If you plan to work with circular only from time to time, then pay attention to the hobby class models from well-known manufacturers (Bosch PKS 55 A, Black & Decker CD601). They are designed for relatively short work (15 minutes work - 15 minutes rest) no more than 4 hours a day. This will be enough for home use, and you will be able to save a lot. Ironically, household models often outlive their professional counterparts a lot, and the developers provide them with a double warranty (2-3 years).

In general, carefully predict the load that the circular saw will receive, being at your disposal, and based on this, select the characteristics of the desired model. We hope we've provided you with enough food for thought.

Construction and renovation work may require cutting large quantities of wood. Naturally, doing it manually, with mechanical tools, is very inconvenient and time-consuming. The real salvation in this case will be the best circular electric saws that we have collected in one rating. Here you can familiarize yourself with their advantages and disadvantages, and, based on the results of this, choose the most acceptable option for yourself in terms of purpose, price and characteristics.

The TOP of the best in this area consists of 5 brands that are popular both in Europe and overseas. The products of these companies are in high demand in the market, but the price range is different for everyone. Here are the companies we are talking about:

Interskol - It is not the first time this Russian manufacturer has appeared on the market of power tools for construction and repair. It provides a huge selection of it, and at very affordable prices. Its products collect numerous positive user reviews due to the optimal ratio of cost and quality.
BOSCH - This is a German company, whose products, in fact, are not much ahead of the goods of the same Interskol, but at the same time they are much more expensive. There are several types of models in its assortment - circular hand-held and cut-off. All of them have good performance, many of them are successfully used on large construction sites.
Hitachi Is a Japanese manufacturer of power tools and gasoline equipment, including some of the best drills. Circular saws account for a large percentage of her collections. They successfully compete in cutting depth with competitors from this rating, offering the disc immersion in the wood by more than 8 cm. And there are enough very powerful devices here, there are also those that operate at 2000 W.
ZUBR - this company can be considered a direct competitor to Interskol, it also supplies the market with high-quality equipment for repairs and construction work. The company has a good reputation among customers and its products are well represented in stores.
Makita Is another Japanese manufacturer of power tools in our ranking, including circular electric saws, and one of the oldest in the world. The company was founded in the early 1900s, and today it is a large-scale production that supplies quality goods to all over the world.

Rating of the best circular saws

When compiling it, we relied primarily on what they write in the reviews. A very important indicator was the frequency of complaints about breakage, opinions about the usability and performance of the tools. Therefore, we analyzed all the advantages and disadvantages of the best electric circular saws, as well as their characteristics:

Engine power (1200-1700 W is considered a good indicator);
Type of power supply (from the mains or batteries, as well as the length of the cord, if any);
The angle and depth of cut, the ability to adjust them;
Tool weight and dimensions;
Ergonomics;
Rotational speed and disc diameter;
Additional functions (backlight, engine braking, etc.).

Best circular saws

In this rating, as you already understood, both models from domestic and foreign manufacturers are presented, and we have selected five of the most useful circular electric saws. Among them there are both options for home use and professional tools.

Interskol DP-165/1200

It looks like an ordinary circular electric saw with not so bright characteristics - the cutting depth barely exceeds 50 mm. The situation is improved by the disk rotation speed of 4700 rpm and excellent power indicators (1200 W). With such data, in 1-2 passes, it turns out to dissolve almost any type of wood. It also helps that there is a button for adjusting the depth and cutting angle. A 4-meter long cord deserves special attention here.

Advantages:

Cost;
Ease of use;
Good outsole;
Convenient;
Excellent riving knife;
Perfectly cuts across and along the fibers.

Disadvantages:

Inflexibility of the power cord;
There is no soft start, which increases the likelihood of overheating and breakdowns.

Despite the rather considerable weight, Interskol DP-165/1200 can be easily used even with one hand.

Immediately I would like to draw your attention to the fact that in terms of characteristics, this hand-held model of a circular type is in many ways similar to other options in this rating, but at the same time it costs 2 times more. Perhaps the only thing that makes it stand out is the engine braking function, which protects both the workpiece from damage and the operator from injury.

Powered by 1400 watts and 5500 rpm, it is clearly designed for professionals. The tool is quite wear-resistant due to the metal base plate and can withstand production conditions of varying complexity. Experience shows that with this circular saw there is no need to worry about a clean cut, as there is a turbo blower option.

Advantages:

Smooth and clean cut;
Power at altitude;
Automatic protective cover;
Adjusting the angle of inclination of the disc;
Does not overheat;
Fittings.

Disadvantages:

Large spread of sawdust;
The cord is twisted, you need to be careful not to accidentally saw it through;
Weight - 4.2 kg, this is not much, but also a lot, because there are much lighter specimens in the rating.

The BOSCH GKS 190 model works more efficiently with a wet bar, but a dry one with a depth of 7 cm may need to be passed 2 or even 3 times.

This is one of the most practical circular saws in our ranking and can be used for sawing different types of wood. It has excellent performance, working fairly quickly and efficiently, without a lot of sawdust, at a power of 1050 watts. There are no complaints in the reviews about the ease of use due to the low noise level and the additional handle. Separately, I would like to note the possibility of adjusting the angle when unfolding the material. But most importantly, it cuts fiberboard, chipboard and other materials with virtually no chips.

Advantages:

Cutting depth;
Inexpensive;
Low vibration;
Rigid wire to minimize twisting;
Comfortable grip.

Disadvantages:

No soft start;
Flimsy tilting mechanism design;
Rear bearing complaints;
Unreliable platform.

Reviews show that those who plan to cut boards not only lengthwise, but also across, may need another saw, since the disc either sticks or makes the edges uneven. If you need to cut wood in one pass, you can count on a maximum cut of 7 cm, and the tool will have to be held at an angle of 90 degrees.

Judging by the power of 1600 W, this electric saw can claim, if not the title of professional, then certainly the use for fast cutting of a large amount of wood. Its inclusion in this rating as such was facilitated by the maximum cutting depth of 6.4 cm, which also speeds up the work. At the same time, the speed of rotation of the disk here is far from the highest - 4500 rpm.

One of the best electric circular saws is also one of the strengths of the operator's protective cover. But not without negative aspects, which include, first of all, the lack of additional functions - backlight, soft start, automatic engine braking. But on average for 2,600 rubles to wish for more is somehow strange.

Advantages:

Good power (1300 W);
Price;
Does not lead to the side;
Easy opening of protection, without jamming;
Cutting depth.

Disadvantages:

Small chips are possible;
The unwinding of the second lamb under the influence of vibration is periodically possible;
Rapid heating.

ZUBR ZPD-1600, despite some drawbacks, can still be called the best of the inexpensive electric saws.

With regard to the characteristics, only good can be said about this model - it passes without problems through fiberboard and particleboard, wood. An accurate and even cut is ensured by adjusting the cutting depth and tilt angle. Working with it is not only effective, but also comfortable - the backlight allows you to do this even in poor light, and the comfortable handle does not let you get tired. It does not claim to be the most ergonomic model, and it weighs 5.1 kg, but for short work the model will be just right.

Advantages:

Turns, like a machine;
Excellent torque;
Magnesium casing and sole;
Protection of the engine with a metal grill;
Soft start;
Fits securely in the hand;
A high-quality cord that is not afraid of frost or high temperatures.

Disadvantages:

"Noisy";
Guide bracket too flexible;
Not universal;
Waste electricity consumption;
Tendency to overheat in hot weather.

In general, the Makita 5008MG seems ideal, but there is one "but" - we recommend working with it only using personal protective equipment for the eyes, since chips can get into them - it is so actively cutting wood. We also recommend stocking up on earplugs due to the high noise level.

Which circular saw is better to buy

The length of the cable here should be from 3 m, this will allow you to work with the tool without carrying. It is also desirable that the device be equipped with a soft start to prevent overheating and reduce the load on the power grid. Also, in order to avoid this, it is necessary that this or that model has overload protection.

If you plan to cut large volumes of wood and thick beams, you cannot do without professional models, the disc of which can penetrate to a depth of 65-140 mm. In other cases, products with lower rates are sufficient. The most optimal speed of its rotation is from 4000 to 6000 rpm.

Summing up the results of this rating of the best circular electric saws, it is worth saying that of the inexpensive, the most acceptable options here will be circular models from domestic manufacturers. It is they who have the most favorable ratio of quality and price. The rest of the units are also very good, but you need to understand that their high cost is often associated only with the popularity of the brand, a particularly striking example of this is BOSCH.

Small production or large repairs, woodwork, plastic, metal work require the use of special tools. The circular saw becomes irreplaceable.

Manual or electric circular?

All circular saws we have considered are divided into two types - portable (hand-held) and stationary.

The portable circular saw is easier to hold in the hand due to its lighter weight. It is suitable for working with parts inaccessible to a stationary saw. Network circulars operate from an outlet and have a cord that sometimes interferes with the operator. Their working time is not limited, and the power is constant. Cordless saws are mobile, do not depend on power outages outside the city, but they are heavier than network saws due to the weight of the battery and require recharging. Replaceable battery packs help extend the life of the hand saw.
Stationary circulars have high power and accuracy and do not put unnecessary strain on the operator's hands. But they take up space, weigh a lot, are difficult to transport, more expensive than manual options.

How to choose the right one?

What to focus on when buying? Recently, buyers looked at the brand and manufacturer of circular saws, and today the general trend of production in China, regardless of the brand's homeland, dictates different selection criteria: the specifics of tasks, budget and tool parameters. Consider the significant technical indicators of inventory and their optimal values.

Power - High performance tool suitable for tough materials. High power provides deep cuts, but makes the saw heavier, energy consumption and tool cost. For home use, stoves with a power of 1000-2000 W are suitable.
Maximum RPM is the fastest rotational speed of the disc. More revolutions result in a cleaner cut. At low rpms, the saw handles hard and uneven materials. The high rotational speed of the disc leads to heating, and this is not suitable for working with plastic.
The size of the blade determines the depth of the saw, depending on the power of the saw. Sometimes several discs of different sizes are included in the package. The choice of the type of tire depends on your application. The fewer teeth on the disc, the higher the working speed, but this affects the quality of the cut.

Consumable parts

A consumable when using a circular saw is a saw blade. Use a disc with the diameter specified in the instructions. Their choice on the market is great. The price depends on the following indicators:

outer diameter (65-500mm);
landing diameter (11-50mm);
the number of teeth (small - 10-40, medium - 40-80, large - 80-90);
inclination of teeth (standard - 5-15gr.);
disc thickness (standard - 3.2).

How to use?

A circular saw is a powerful and dangerous tool in inexperienced hands. There are many tutorial videos on working with specific models. We have compiled a list of general guidelines for beginners:

prepare a work area with sufficient natural or artificial light;
choose tight-fitting work clothing;
measure the material for cutting in advance, make the necessary marks;
use a mask or goggles to protect against sawdust;
choose the smallest cutting depth;
set the guide in accordance with the size of the part;
saw through the part 3-5 mm;
continue cutting without stopping in the path of the blade;
use scotch tape to avoid chipping.

bosch GKS 85 professional circular saw

Woodworking has always been and remains a very labor-intensive activity, and the appearance of a circular saw in the first half of the 20th century made it possible not only to facilitate wood cutting, but also to significantly increase labor productivity. As usual, after the actual invention of the cantilever wood machine, whose honor belongs to Raymond DeWolt, the principle was taken up by other equipment manufacturers who brought their own improvements. For example, Sullivan and Mitchell made a circular saw, A. Steele patented the integrated one, and A. Emmons patented the side drive of the cutting disc. Finally, do "Circular" The German company AEG managed to become truly affordable for consumers, which began producing products designed for a household network with a voltage of 220 V. A modern circular saw is a rather perfect device with a wide range of additional options, and there is nothing special to invent here. Manufacturers can only improve the quality of their products, bringing it closer to the quality of top models.

Working with an electric circular saw

The device of a modern circular saw itself is quite difficult, since it combines high requirements for work safety and no less high requirements for the accuracy of settings, of which there are quite a few. Thus, it is categorically not recommended to carry out independent repair of a circular saw due to the fact that it is impossible to achieve factory accuracy of adjustments in artisanal conditions, and this can negatively affect accuracy, and most importantly, on the safety of working with the tool.

A circular saw (it is also commonly called "circular" or "parquet") is mainly used for slitting wood and materials based on it, including plywood, chipboard (chipboard), fiberboard (fiberboard), oriented strand (OSB) boards and MDF. In addition, the circular saw does an excellent job of cross-cutting. However, when using special discs and changing settings, the unit can also be used for cutting laminate, sandwich panels, as well as various plastics (including plexiglass) and even slate. The circular saw handles almost any sheet material, although there are limitations. First, a circular saw can only cut in a straight line, which it holds perfectly. Secondly, a circular saw is not capable of cutting bricks, concrete, plaster and other dense materials, although some models (for example, Makita 4101RH) are equipped with a diamond blade and a water supply system.

It is worth noting that a circular saw for cutting metal, in fact, is the most versatile device - if the unit is able to cope with metal, then softer materials are even more suitable for it. Unlike conventional angle grinders (angle grinders), or "grinders", where an abrasive wheel is used, a circular saw for metal uses a toothed disc made of special tool steel. A machine like the Makita 4131 can easily cut pipes, stainless steel, various profiles, not to mention sheet steel and non-ferrous metals and alloys. Compared to our traditional "grinders", such a saw has many advantages, namely:

Circular saws for metal have been successfully used for a long time in Western Europe and the USA, while in our country they appeared relatively recently. Naturally, domestic experts appreciated these devices. For example, the EVOLUTION 230 EXTREME circular saw can handle steel sheets up to 12 mm thick and steel profiles and pipes up to 4 mm thick. Naturally, wood and various polymeric materials are also not a problem for her.

Plunge-cut circular saw

This type of circular saw is designed for the manufacture of grooves, slots, grooves and other similar works. For example, it allows you to cut an opening in the countertop for installing a sink, since its design allows you to insert in any place, not just from the edge of the material.

Circular plunge-cut saw AEG TS 55 E

For example, the makita sp6000set does not have an automatic lower guard, and the blade is mounted above the base plate. When the unit is started, the wheel lowers and cuts. Cutting depth is adjusted with millimeter precision.

The submersible circular provides rich opportunities for floor repair, roofing and other works. Another feature of this type of saws is the ability to correctly cut multilayer and laminated materials. In order to avoid the occurrence of chips on the decorative coating, cutting is carried out in two passes. The first cut cuts to a shallow depth. Cutting can be carried out both perpendicular to the plane of the material, and at a given angle.

Cordless circular saw

As battery technology advances, off-grid circular saw models are increasingly competing with traditional networked models.

Makita hs300dwe cordless circular saw is a great choice

Moreover, the field of application of cordless saws is quite wide.

It is especially important to use them at a height, for example, when installing or repairing a roof. The main problem with cordless saws was the short operating time, since the power consumption is quite high, which means that a large battery is needed, which affects the charging time. However, modern models (such as the Makita hs300dwe) equipped with two batteries are capable of continuous operation - it takes 30 minutes to fully charge the battery. When it comes to technical specifications, namely power and torque, models such as the Bosch GKS 36V-Li, which allow cutting depths of up to 54 mm, are in no way inferior to traditional network models. And in terms of the convenience of working with such a tool, it has no equal.

What to look for when choosing

Perhaps the main parameter of a circular saw is the diameter of the cutting disc, since it is this that ultimately determines the depth of cut, according to which the models are conventionally divided into classes. As the diameter of the disc increases, the power of the motor increases, and the design also becomes more complicated due to the fact that it is necessary to provide the necessary torque to maintain the speed within certain limits with increasing load. The stabilization system is also becoming more complicated, which provides a low level of noise, vibration, runout and prevents the disc from jamming in the workpiece. All this leads to an increase in weight, dimensions and, accordingly, the cost of the unit. On the other hand, this saw can cut more massive workpieces.

As for the classification, which is rather arbitrary, it depends on the diameter of the cutting wheel, but is still determined by the maximum cutting depth that the circular can make. This parameter is always indicated in the technical data sheet of the product, both for perpendicular saws and for beveled saws. So, circular saws can be roughly divided into the following classes:

40-50 mm - for working with sheet materials - household
50-65 mm is the most common grade, suitable for most jobs
65-140 mm - professional models

As mentioned, the classification is very arbitrary. For example, one of the leading manufacturers of professional equipment, the Japanese company Makita, has its own classification, and does not produce models of the "light" class at all. It is worth noting that Makita circulars are a kind of benchmark in this (and not only) type of power tool. Thus, when choosing a model for personal use, one should be guided by the need, namely the thickness and type of material with which to work. An important factor in the choice will be the maneuverability of the tool, which is the higher, the less power and, accordingly, weight. For comparison, the Makita 5103R model with a blade diameter of 270 mm and an engine power of 2100 W has a mass of 9.4 kg and is capable of cutting at a depth of 100 mm, while the INTERSKOL DP-165/1200 model with a disc diameter of 165 mm and an engine power of 1200 W weighs 4.5 kg and is capable of cutting to a depth of 55 mm. When choosing, it should be borne in mind that in order to cut a thick workpiece, you can cut from both sides, since it is not at all necessary for the cutting disc to go through the material.

professional powerful circular Makita 5103R

It is also customary to classify circular saws by power. A more powerful motor will provide stability in operation, allow for longer continuous operation, which means faster cutting of material. Naturally, the power and diameter of the cutting disc have a direct relationship, so the division into power classes is also quite arbitrary, namely:

models up to 800 W can be classified as household
models from 800 to 1200 W are universal
models with power over 1200 W are considered to be professional.

The next selection criterion can be considered the speed (frequency) of rotation of the disk. To some extent, the cleanliness of the cut (no chips) depends on the speed of rotation, but it is also influenced by the type of disc, namely the shape and size of the teeth. It is also worth considering that the higher the speed, the lower the value of the torque developed by the unit. Finally, speed affects how much the workpiece heats up, so for some plastics, high-speed models are not suitable - the edges of the workpiece will simply melt. Thus, you should pay attention to models with the same tool diameter and choose the rotation speed that best suits the nature of the work. On the other hand, there are models with variable speed of rotation of the disk, but they will be correspondingly more expensive.

Electronic protection systems

The modern circular saw is equipped with various electronic systems that ensure operator safety and extend the life of the machine itself. It should be borne in mind that the circular is a highly hazardous unit, so if there is a possibility, then you should not save on your own safety. In addition, a more "advanced" model in terms of electronic systems is guaranteed to last longer, since electronic systems ensure the safety of the mechanical part from increased loads, shocks, etc.

First of all, mention should be made of the so-called "constant electronics", which monitors the maintenance of a constant disk speed as the load increases or decreases. For example, the DeWalt DWS520K model has a special sensor that monitors the shaft speed and regulates the power output. Thus, a constant speed is achieved, and jamming of the disc in the workpiece is practically excluded. All this has a positive effect on the quality of the cut. Of course, in order to maintain the rotation speed with increasing load, the unit must have a certain power reserve, which is implemented in models of the middle and high class. Some models (for example, Metabo KSE 68 Plus) are equipped with a system for presetting the idle speed, which may be necessary when cutting various materials. In this case, it is the preset frequency that will stabilize. However, many models without this option are also equipped with constant electronics.

As you know, the starting current of an electric motor is many times higher than the operating current, which can lead to an overload of the power grid. To prevent this phenomenon, many saw models are equipped with a soft start system. An additional positive factor for the presence of such a system is a decrease in the load on the mechanical part of the unit during start-up, the absence of jerk and shock loads, which increases the durability of the unit, as well as the comfort of working with it. An example is the Fiolent PD 3-70E model.

Another useful option is tool overload protection. This may be the operator's excessive diligence, who applies excessive efforts to the circular, or a sharp voltage drop in the network. In this case, the protection system will automatically turn off the power, which will avoid the failure of the unit and save the owner money for its repair.

Finally, "advanced" models can be equipped with an electrodynamic brake. This system stops blade rotation almost instantly after the operator releases the power button, avoiding injury and protecting the machine and workpiece from damage.

Advanced mechanics

One of the most unpleasant phenomena when working with circulars is the disc jamming in the workpiece. This could damage the motor and cause kickback. The so-called slip clutch is designed to cope with this problem. If the disc gets stuck "tightly", the coupling will release the motor shaft and allow it to rotate further to avoid burnout of the windings. It is a very reliable system, so it only works when needed.

A rather familiar mechanical element of protection against spontaneous or accidental activation is an additional button, which must be pressed simultaneously with the main one. In many tools, this button is used to fix the main switch in the working position. However, in the case of a circular saw, this method does not apply - the power must always be turned off when the switch is released.

From time to time it is necessary to replace the cutting blade. For this, it is necessary to fix the shaft and unscrew the fastening nut. Some models (Bosch GKS 65 CE Professional) are equipped with a shaft locking mechanism in any position. Also, the shaft can be fixed in one position or not fixed at all. In the latter case, to replace the disc, two keys must be used, one of which must hold the shaft.

One of the most important parts of a circular saw is the base plate. It always contains various regulating mechanisms and fastening elements for additional auxiliary parts. The base plate can be made from stamped steel of sufficient thickness or by casting, usually based on aluminum alloys. It is believed that the professional unit is always equipped with a cast base plate, but some models (Bosch GKS 65 CE Professional) are equipped with a stamped plate.

Changing the angle of inclination of the cut is carried out by changing the angle of inclination of the base plate relative to the disk. By default, the plate is perpendicular to the disc, and if necessary, it can be set at a fixed angle - 30 °, 45 °. There are models that allow a greater tilt angle of the slab - up to 55 °. The base plate also contains elements for adjusting the cutting depth. The main requirement for the depth adjustment system is the accuracy and reliability of fixation. The ease of making the necessary changes is also important - for professional activity, time plays an important role.

Harvesting boards with a circular saw

A good circular saw allows installation in a stationary position - a kind of machine comes out. Naturally, the heavier and more massive the unit, the more relevant this functionality will be, although many lightweight models also provide for this possibility.

Ensuring straightness of the cut is essential. This can be achieved both with standard tools (most saws are equipped with a stop to ensure parallelism to the edge of the material), and additional equipment, which is purchased separately. However, it is often necessary to cut along the markings. To control the line, a special opening is made in front of the base plate. However, there are also more modern solutions. For example, the EVOLUTION 180 EXTREME device has a special laser pointer that just needs to be aligned with the marking line.

In view of the increased danger of working with a circular saw, it is compulsorily equipped with an automatic cover that shifts at the start of work, and after the end of cutting, it automatically returns to its original, closed position under the influence of a spring. In order to prevent the blade from jamming during operation, any saw is equipped with a riving knife, which does not allow the already cut material to squeeze the blade.

Ergonomic features of circular saws

Despite the fact that the circular saw is designed to facilitate the processing of wood and other materials, the process remains quite laborious. Therefore, the ergonomics of the unit when choosing is of paramount importance. And here, special attention should be paid to the shape and location of the handles. Naturally, everyone should choose a tool in accordance with their own tastes, habits and physical characteristics. That is why there is a fairly wide variety of forms and arrangement of device controls. Particular attention is usually paid to the shape of the front handle - it can be straight, perpendicular to the plane of the cut material, or mushroom. The second option seems to be more preferable, since it gives more degrees of freedom. However, there are also those who prefer the first option. Some manufacturers make models for left-handed people. If we talk about the material of the handles, then the rubberized ones have recommended themselves best. They allow you to control the instrument in the best possible way.

special overlay for adjusting the width

When choosing an instrument, you should consider several options, hold it in your hands to feel their weight and balance. This is especially important for those who have to work a lot "on site" - in this case, the convenience of the tool is especially important. An important feature of this or that model is the visibility of the cutting site, depending on the design, it can differ significantly. When working with a saw, an effective blowing of the cutting site should be organized to remove sawdust. Some models are equipped with a connection for a vacuum cleaner and a sawdust bag. For this, a special container can be provided.

Separately, you should pay attention to the location of the power cable, which can be cut through inadvertently. Most preferred is a rear arrangement with a long and stiff entry sleeve. As for the length of the cord, it is better if it is long (3-4 m) - during operation, the carrying block can create perceptible interference.

The saw motor has parts that need to be replaced periodically - brushes. Choose models that provide quick access to the brushes. In this case, you can replace them yourself. Otherwise, it may be necessary to contact a service center, and this is an additional cost of time and money.

In a store, it is unlikely that it will be possible to test the instrument in practice, but it is imperative to start it and listen to how noisy it works, how strong the vibration is. Several models should be compared for these indicators. The circular motor is cooled by the air flow generated by the rotation of the disc. The stronger it is, the better the cooling will be. Also, the air stream blows off the formed sawdust.

Video circular circular saw

If the circular is supposed to be used periodically, for small jobs, you should pay attention to the "hobby" class tool, which is in the assortment of many well-known brands (for example, Bosch PKS 55 A or Black & Decker CD601). The operating mode of these models requires a 15-minute break after 15 minutes of continuous operation, and such a saw should work no more than 4 hours per day. But the cost will be much lower, and the warranty even longer than for a professional tool (2-3 years versus 1 year for a "professional"). It is worth noting that a professional tool, due to intensive use, often really serves a shorter period than a household one, so if the price is not the main thing.

As for the brands that have proven themselves from the best side, then for household needs you should pay attention to the products of the companies Black & Decker, Skil, Bosch (green) and the prices of saws are reasonable. If it is to be used in professional activities, then the models of the Japanese companies Makita and Hitachi, as well as blue Bosch, are out of competition.
