ABSTRACT:
A high speed hand tool includes a saw disc having less than ten teeth, preferably four. Each tooth has a radial flank, which preferably inclines forward in the cutting direction, and a tangential flank, which has a small clearance angle. The teeth may have a greater thickness than the disc itself which thickness, in that case, diminishes in a direction opposite to the direction of rotation. Alternatively, the teeth may be offset alternately to the right and the left. The invention also comprises an adjustable protective device which enables setting the depth of a perpendicular saw cut.
