What can be done with a circular saw
The principle of operation of this unit is based on the rotation of the cutting disc by an electric motor. The saw design is presented in two versions: manual or stationary. An important difference between these two versions is that the force from the engine to the disk in the stationary model is transmitted through the belt, while in the manual model the disk itself is fixed on the shaft. The saw can cut wood both along the fibers and across them, cut a quarter. The tool can be used to saw off soft metal, plastic if you use special discs.
