Power
The power of the device is a determining factor in determining the depth of cut and the permissible density of the material being processed. Here the more. All the better.
Manufacturers install power plants on their models, the power of which depends on the intensity of use:
- Household. Up to 800 W
- Universal. Here is 800 to 1.2 kW;
- Professional. Here is 1.2 to 5 kW.
It should be understood that a more powerful propulsion system provides better performance, stability and continuous running time.
Power affects Not only the performance of the device, but also its weight and size characteristics. You should not chase very powerful models, which may simply be inconvenient to perform certain types of work. For example, for most roofing work, specialists use compact and ergonomic battery models.
Body material
In the production of circular saw bodies, manufacturers use impact-resistant materials that can withstand high loads and temperatures. Among the most common are:
- Metal. Typical for professional equipment;
- Heat-resistant plastic. It is distinguished by its low weight, which is a characteristic feature of household appliances;
- A mixture of metal and plastic is considered by experts to be the ideal option. Metal increases the resource of the tool, and plastic significantly reduces its weight.
Cordless circular saws
These compact devices are hand-held circular saws powered by a rechargeable battery. Battery models are used on construction sites where there is no way to connect the tool to the power grid. This type of dust is designed for a short period of operation, which, depending on the battery capacity, can be from 15 to 60 minutes.
- Compactness;
- Mobility;
- Ergonomics.
- Short time of continuous work;
- High price.
Tip: Before choosing a cordless circular saw for your home, ask your dealer for models with two batteries and a charger included. Such a complete set will significantly increase the operational capabilities of the tool.
Rpm
The speed of the cutting blade affects the quality of the cut. The higher. All the better. However, one should not forget that the higher the shaft rotation speed, the lower its torque. When cutting material, the cutting tool inevitably heats up and the higher the speed. The higher the temperature. For example, plastic tends to melt at high temperatures, which is fraught with jamming of the disc and engine failure.
Hand circular saw
This is a fairly compact and powerful tool, which is successfully used by home craftsmen and professional builders to solve a wide range of tasks. To complete the cut, the operator moves the dust to the stationary workpiece.
Depending on the design and cutting tool, handheld models can be:
- Wood;
- For metal.
The first ones are intended for longitudinal and cross cutting of wood, cutting sheet products of woodworking. They can work with cutting discs of three types: serrated, tipped with carbide metals, with variable tooth and reduced kerf, universal multi-purpose discs.
Manual circulars for metal are designed for cutting steel sheets, cutting profiles, pipes, non-ferrous metal products. Can be used with toothed and abrasive discs. Equipped as standard with multi-purpose toothed cutting tools.
Before choosing the right hand-held circular saw, you should decide what type of tool you need.
- Household saws are inexpensive and easy to use. Such models are characterized by relatively low power and minimal functionality;
- Semi-professional models are quite versatile, they can be used to perform most complex jobs and solve everyday problems. Equipped with a sufficiently powerful power plant, but do not have the functionality inherent in professional equipment;
- The professional tool is characterized by high power, endurance and functionality.
The advantages of manual models:
- Ease of use due to the relatively low weight and compactness of the device;
- High performance;
- Optimum price-performance ratio.
- Injury hazard;
- High noise and vibration levels.
Tip: before choosing a hand-held circular saw for a summer cottage, decide how long you plan to work with this tool. Household models can work continuously for no more than 25-30 minutes. If you plan to use continuously circular 40-50 minutes, then pay attention to professional-level models.
Bevel cut adjustment
One of the key points when choosing the right circular saw for your home is the ability to make miter cuts. This function is provided by the design of the platform, which can change its position along the axis of the cutting disc.
Depending on the model, the tilt can be adjusted by 30, 45, 55. Adjustment of the platform position is made by a wing or clamping mechanism.
Features of hand saw blades
Even with noise and vibration suppressors Wear hearing protection.
Today, almost all manufacturers of circular saws also produce discs that have solid-state surfacing to their units. Each such device has hard overlays on the teeth. They significantly expand the scope of use of circular saws. NOT every disc has the same number of teeth. If you choose the right number of them, you can work with almost any material under given conditions. These discs are much stronger than ordinary discs.
An analogy can be drawn here with a car. For him, winter and summer tires are produced, which are used depending on the season that is outside the window at the moment. This situation is also typical for saw blades. When it comes to working with thin materials, then discs with a large number of teeth and a fine finish are selected. It is quite difficult to work with these disks, as they wear out quickly at high speed. It is another matter when it comes to discs with large teeth. With their help, you can always determine the optimal mode of cutting wood.
In the safety of the work itself
The fewer the teeth, the less the saw heats up.
The safe operation of your circular saw is very important. If instructions are attached to the dust, then it is imperative that you familiarize yourself with it before starting to operate the tool. It contains the rules and regulations of behavior during work. If you use the tool incorrectly, you can damage one of your organs, and this is unacceptable. The instruction manual does not always contain a complete picture of the rules. Therefore, it is worth talking in more detail about how to behave correctly when working with such a tool.
When it comes to working with thin materials, the circular saw should contain as many teeth as possible. In this case, the material will be cut very easily. In the case of coarse material, it should contain a small number of teeth. In the event that the blade is chosen incorrectly, there is a high probability that the saw mechanism itself will gradually overheat, and this most often leads to failure of the power tool. It must be handled very carefully in order to exclude all possible breakdowns.
The speed of the saw is very important during the operation of the saw. In this case, it should be calculated depending on the material to be cut. The correct choice of sawing modes can significantly increase the service life of the tool and the working discs themselves.
Practical advice
Saws with a large positive tilt angle cut quickly and aggressively.
Now you can go to the physical characteristics of circular saws. The convenience of a person’s work largely depends on this, and the choice itself. Before buying dust, be sure to pick it up. It should be easily held in them. Needed Pay attention to whether there is protection against accidental starting. The life of a person working with this tool directly depends on this.
Do not forget that these saws can cut wood Not only at right angles, but also at an angle. For this, special devices are used, which hold it in a given position. Usually a circular saw cannot have a tilt angle of more than 45 , but this is enough to produce the correct spray.
For a circular saw, the immersion depth in the tree can be determined. Most modern devices have this option. It should be remembered that the movement of the tool in this case is limited only by the vertical axis.
Cordless circular saws can also be found on the market today. Such specimens are of little use for the home. They have limited power characteristics. Plus, they have a fairly short duration of work. They only find their place in places where there is no direct access to electricity. This is where they are irreplaceable.
Main characteristics
Cutting edge shapes depending on the application of the circular saw.
Before purchasing a specific hand-held circular saw for private use, it is worth thinking about the technical characteristics of this power tool. The effectiveness of her work largely depends on this. A circular saw for a home must fully comply with the volume of work, which it is planned to use with it.
Almost all modern home saws have a single-phase motor. over, they most often work from a regular outlet. It is worth noting here the fact that such a tool is equipped with a motor that has a brush, which means that it can wear out over time. No brush is everlasting. If the brush starts to wear out, that is, its graphite base is worn out, you should think about replacing it.
In fact, this is not difficult. Modern brush assemblies are fairly easy to maintain. The saw motor is its main part. The characteristics of the instrument itself depend on what its power will be. So, the engine power. This is the most important parameter of any circular saw. You definitely need to pay attention to it before buying.
Circular saw anatomy.
Here, what will be the engine power of a saw for a house, depends on whether it can cut rough wood and what size discs can be installed on it for work. The pattern here is very simple. The higher the power ratings of the engine, the coarser the wood it can handle.
The weight of the tool and its cost directly depend on this. Powerful saws cost much more than those that have small overall dimensions. When choosing a saw, it is worth thinking about what kind of work will be performed with its help. If you plan to saw thin plywood, then you can completely get by with inexpensive average power units.
A very important parameter of any saw is the number of revolutions. At the same time, different parameters are often optimal for different woods. Therefore, it is very important that the home saw contains the option to adjust the spindle speed.

What else to look for when choosing a circular saw?
It is important to select the correct saw blade speed to avoid rough spraying.
So, now every reader knows which characteristics are the most important for a saw. It is worth talking in more detail about what is necessary first of all Pay attention when choosing a tool.
Be sure to pay attention to the cutting depth. This parameter is very important for work. If a person is going to work with thin materials, then, of course, the cutting depth for him is not of any priority. However, you also need to think about your future work. In the future, there is a high probability that you will have to work with other materials, so it is better to choose the cutting depth with a small margin.
You need to pay attention to the cover of the disc itself and its reverse side. They must necessarily be made of metal. However, things have recently become relative, thanks to the development of China’s industry. Even a metal instrument originally from this country will be inferior to plastic options, for example, from Japan.
If you plan to work not with one material, but with different ones, you need to Pay attention to the possibility of adjusting the speed on the dust. This option allows you to correctly select operating modes with a wide variety of materials, which significantly affects the service life of the saw itself and the discs for it.
Protective coatings on the saw blade for increased wear resistance.
It is better to select a unit that will allow you to make cuts at a certain angle. In this case, the scope of use of the tool is significantly expanded, even when it comes to using it at home.
An option such as blocking accidental activation will also be superfluous. It will allow you to protect human life and health.
Tool ergonomics always comes first. If a person is at a loss in the final choice of one or another unit, then he must definitely try to hold it in his hands. This will greatly facilitate the work with the saw. If she is easily held and takes a comfortable position, then you need to take this particular option.
It is desirable that the scope of delivery of the circular saw included an additional disc and a rip fence, which will greatly facilitate the work with the tool when it comes to working with thin materials. Ergonomics play an important role here.

Self-selection of a circular saw
Nowadays, circular saws are becoming more and more popular among ordinary people. A few years ago, this tool was considered exclusively professional, however, today circular saws are part of the private life of an ordinary person. They are quite comfortable. With their help, you can cut any wooden parts. over, it does not depend on how thick they are. All work is done in a matter of minutes. This tool is intermediate between a chainsaw and an electric jigsaw. A chainsaw is usually used for rough sawing wood. This is about simply splitting a log or tree. There can be no question of any subtlety of work.
Circular saw models with rubberized handles are more comfortable to use.
In the case of a jigsaw, the situation is exactly the opposite. Here we are talking about using for delicate work. Large wooden parts will NOT spray them with this tool. That is why circular saws are used in modern society. It can handle even the thickest wood pieces with care. How to choose a circular saw will be discussed further.
