Rating of the best models
The concept of the best models in the case of circular saws is very vague, because each consumer starts from his own needs. In addition, the model lines of all leading manufacturers are regularly updated, so any allocation of seats does not seem appropriate. With this in mind, let's take a look at several popular models from leading brands.
- Makita HS7601 is one of the best home solutions. With a modest price of about 4 thousand rubles, this device is equipped with a 1200 watt motor. A disc with a diameter of 19 cm rotates at a speed of more than 5 thousand revolutions every minute, allowing you to cut materials up to 6.5 cm thick. The weight of the device with all the characteristics is quite small: only 4 kg.
- Bosch GKS 190 at a price of the same 4 thousand rubles is already a worthy semi-professional solution. Although the blade has the same diameter of 19 cm, the thinner spindle allows to increase the maximum cutting depth up to 7 cm. In terms of rotation speed, this saw is one of the most outstanding, providing 5.5 thousand revolutions per minute. The increase in power and the number of revolutions practically did not affect the weight: it is 4.2 kg.
- Interskol DP-165/1200 is a typical representative of the domestic industry, which is popular due to its lower cost: it does not exceed 2.5 thousand rubles. In this case, the manufacturer offers a household saw with more modest performance than the Makita HS7601: with a power of the same 1200 watts and a reduced disc with a diameter of 16.5 cm, the rotation speed did not increase, and even dropped to 4700 rpm. At the same time, both the cutting depth (decreased to 5.5 cm) and weight (increased to 4.5 kg) suffered, but for this price it is still one of the best solutions for home use.
- DeWALT DWE560 is an alternative semi-professional solution with a capacity of 1350 watts from a well-known American manufacturer. The specified power allows the 184mm disc to rotate at up to 5500 rpm per minute, cutting sheet materials up to 65mm deep. The advantage, albeit insignificant, will be some weight reduction: of all the models described, this is the lightest, since it weighs 3.7 kg.

What are the additional functions
On saws where a circulation mode is provided, you need to learn how to work in compliance with safety measures so as not to endanger not only yourself, but also those around you. Product manufacturers produce saws with additional protective functions:
- smooth start;
- speed fixation according to preset;
- with electrodynamic brake and sliding couplings;
- from engine overheating;
- fuses against unintentional start-ups.
The ergonomics of the device, how the handle is located and its shape have a great influence on the convenient operation of the device:
- straight;
- mushroom;
- staple.
If the rubber cover is attached to the handle, the tool will not slide in hand... Before buying, you need to familiarize yourself with:
- how carbon brushes are replaced;
- where the power cord is located;
- with methods of disposal of wood waste;
- with an overview area and weight category.
When the technical characteristics of the tools are known, you can begin to review the rating based on expert assessments and user reviews who have experienced their electrical unit in practice. We were able to determine how much the price is commensurate with the quality and service life, for which the manufacturer vouched in the documents when issuing the guarantee.
Types of circular saws
First, let's figure out how a circular saw differs from a circular saw. In fact, there are practically no differences, both names are used in parallel to denote the same class of instruments. But still, a circular saw is more often called an apparatus on which, instead of a headset with teeth, you can install a smooth circle for cutting metals.
Such work is often performed using an angle grinder (in everyday life - "grinders"), but the device in question does it better:
- you can cut metal at an angle;
- the workpiece does not heat up;
- productivity, quality and cutting speed are higher.
Now about the types of saws:
- Stationary "circular" (circular machines)... Not so long ago, it was the only type of device in this class. They are table-mounted and designed for large volumes of work. Cutting is done in the same way as on a stationary device. They are used in professional activities.
- Also professionals use table saws... They are attached to the table with clamps and can be transferred to another surface. Such devices take up less space and are often used in production where there is a lot of sawing wood to be done.
- Circular saws... Held in the hands. They are used both by professionals and in everyday life. Their purpose is to cut small-sized wooden products in moderate volumes. Also, you cannot do without such a tool when preparing sheet materials.
Separately, it is necessary to consider the types of circular saws of a submersible type. They differ in that before starting work, the disc is raised above the surface to be treated and covered with a casing. You can set the cutting depth in advance and start working. The plunge-cut saw is convenient to use when cutting out windows, making blind cuts.
Sometimes novice carpenters ask the question - what is parquet? This name is used (but not often) for the class of plunge-cut saws - with their help you can perform parquet work.
By the type of drive, all considered devices belong to the class of power tools. Most of them are powered by 220 volts. There are also rechargeable models. They are more mobile, but have
reduced power and run time limited by battery capacity
Mobility is not the most important quality for such tools, so you need to choose battery devices only when you plan to work in the absence of a power supply
How to choose?
When choosing this or that electrical appliance, you need to understand two things: for the sake of what tasks it is acquired and what basic characteristics should it possess for the sake of their successful solution. In the case of an electric saw, the most important point is usually the power of the engine: it depends on what size the disc is and at what speed it can rotate. The larger the circles you plan to use, the higher the power of the unit should be, but do not forget that an increase in this indicator also increases the weight of the device. In general, models with an engine power below 1.2 kW are considered to be household and designed only for simple tasks, and units more powerful than 2 kW are considered professional.
The cutting depth is another important factor, because if this indicator is too small, the saw simply will not take the material intended for cutting. This criterion depends not only on the power of the engine, but also on the size of the disc socket. There are only four main typical sizes: household # 1 (up to 4.5 cm cut), semi-professional # 2 (5-5.5 cm), professional # 3 (6-7 cm) and very rare industrial # 4 (up to 14 cm). Experts advise choosing a cut-off wheel with only a small margin of cutting depth, otherwise it is almost impossible to guarantee the stability of the workpiece and the tool.
The speed of rotation of the disk in the case of dense wood should be as high as possible - so the cut will be more accurate, and the productivity will increase significantly. For cutting plastic, this logic does not work: during operation, the circle can heat up significantly, and after all, the plastic workpiece can melt under such conditions. Expensive universal saws, designed to work with different types of materials, allow the operator to adjust the speed. At the same time, the widespread opinion about a direct relationship between engine power and maximum speed does not always correspond to reality, because in this equation there should be a place for the weight of the disc. Many modern models also have the function of cutting at an angle.
If you are interested in a circular saw for cutting boards or plywood at home, this function is unlikely to come in handy, but for the needs of professional construction it can be critical.
In addition to the main technical characteristics that affect the production capabilities of the tool, it is impossible not to pay attention to many useful additional functions. In many of today's models, the start is specially carried out by two buttons that are remote from each other - thanks to this, the unit will not start accidentally, which minimizes the risk of injury
The good thing about the smooth start is that the disk picks up speed, albeit quickly, but gradually, which is why the engine does not experience an instant load and wears out more slowly. Many models provide in their design the presence of a special nozzle for a vacuum cleaner, while others even have a stationary device for removing shavings - all this allows not only to keep the workplace clean, but also to prevent dust from getting into the eyes or lungs.

Domestic copies
ZPD 2000
According to user reviews, our Bison or ZPD 2000 are no worse than foreign circulars.
They work with material:
- dry;
- raw;
- hard and soft.
At the same time, regardless of the change in the direction of the cuts, the quality does not decrease even when a blunt disc is installed with only a few teeth in it. Work with the unit is noted:
- smooth running;
- good power;
- endurance;
- evenness of the cuts;
- convenience.
Interskol DP1901600 M
The next Russian model is Interskol DP-190/1600 M.
The excellent development of the circular design was noted, where every moment is carefully thought out. The models are well assembled, so there is no wobbling or backlash in the details.
The advantages of the device include properties:
- cast base power;
- the convenience of levers that adjust the height;
- cutting corners;
- ease of changing saw blades;
- light weight category.
Consumer claims to cords, they do not withstand frost begin to tan.
Saw blade ergonomics
For domestic needs, a hand-held circular saw is most often used, which means that the issue of ergonomics should be given special attention. At the same time, it will not work to give any unambiguous recommendations, since everyone has their own concept of convenience
Left-handed right-handed
About 10% of people on Earth are left-handed, and manufacturers must take this into account when releasing mirror models of instruments.
Handle shape and location
If the rear handle is more or less standard, then there are at least three varieties of the front handle: straight, mushroom and staple. The first is more suitable when working with a saw "from oneself", the second is more convenient to guide the saw from the side, and the third is universal, but larger than a mushroom.
Straight.
Mushroom.
Staple.
Observation area
Depends on the design features of each tool, so before buying it is better to evaluate it with your own eyes.
Power cord
To prevent the wire from twisting at least near the saw itself, the cable is led out of its body through a long and rigid inlet sleeve.
Replacing carbon brushes
It is not required so often, but in any case it is better if there is a special window for this operation. Additionally, the brushes can be self-disconnecting - when grinding the graphite rod, the chain is broken, and there can also be an indication of the status of the brushes.
Weight distribution
To evaluate it, you need to take one by one and just hold in your hands several different models of circulars. This will immediately show you exactly what to look for.
The store likely won't have a board or similar piece to test the saw's performance under load.And sellers do not particularly welcome such experiments, although they should simply plug the saw into the network. This will allow you to check at least the stability of operation, the noise level and the absence of vibrations at idle. Also, the airflow can be used to assess how well the engine cooling works.
These are all the main points that must be considered before choosing a circular saw for a summer cottage or at home. The main thing is to remember that the wrong choice of a power tool is, at best, an overpayment for unclaimed functions and increased power consumption, and at worst, its uncertain operation and the possibility of failure at the most inopportune moment. We hope this review will help you choose the right model.
What is it and what is it for?
The circular saw is a powerful machine that can be used to cut large quantities of wood, laminate, soft metals and some other substances. Who exactly invented the circular saw, now it is impossible to say. There are a number of candidates - residents of the territories of modern Germany and England.
Two things are clear: work on this invention was carried out in many places in the last quarter of the 18th century, and more or less widespread use of circular saw designs close to modern ones began after the end of the Napoleonic wars.
The high performance of the mechanism is greatly overshadowed by the fact that it is only suitable for precisely directed straight cuts. The slightest deviation to the side is impossible for technical reasons.
Despite the similarity in design, there are significant differences between specific models of circular saws, affecting:
- total capacity of the installation;
- productivity at work;
- the thickness of the material to be cut;
- a set of auxiliary functions.
