The work of a circular saw is based on the rotation of an electric motor. In this case, the torque is transmitted to the gearbox and to the toothed disk, through which the sawing takes place. As a result, the tool cuts material of different density. We have compiled a rating of the best circular saw blades.

How to choose a good circular
The circular saw is quite complex in design, carries a potential traumatic hazard. Many types of circular saws are designed for specific jobs, designed for a specific intensity. It is possible to decide what to choose from the trade assortment only if you have an accurate idea of the area of use. Some characteristics will be required first of all, others can be overlooked as unnecessary. It is recommended to study the assortment of the store.
Most often, circular saws are divided by purpose: professional saws or for everyday life, the load on which is less, as well as the cost. The second issue is the work performed. The main characteristic is cutting depth... Certain dimensions, weight and cost correspond to this functional parameter. In everyday life, the following types are used:
- Small toolcutting depth 40 or 46 mm for thin materials. It is compact in weight and dimensions, and has maneuverability.
- Average, 50 or 55 mm. This type is popular, it does not require much physical effort during work.
- Big, from 65 to 70 mm can be used when building a house. It has significant productivity, in some cases it provides for the possibility of a stationary installation.
In addition to the size and cutting depth, the following characteristics play an important role.
- Power... The larger it is, the less force will have to be applied to cut hardwood. The risk of overloading and excessive heating will be reduced. But the weight will be greater and the cost will be higher.
- Rotation frequency, the possibility of its adjustment. It will be easier to cut hard materials at high values. The ability to adjust the speed allows you to select the desired mode.
- Stabilization function maintains the speed at a constant level. Typical for a professional tool.
- Smooth start provided by the starting current limiting unit, excludes jerks when turned on. It also reduces shock loads and wear.
- Motor protection against loads carried out by means of an electronic control system. The tool shuts down when a hazard occurs.
- Disc braking by electronic system stops rotation after shutdown.
- Safety clutch - mechanical addition for safety. Protects the saw when a blunt blade hits hard material in case of jamming. Compensates for motor inertia.
