Method for improving a circular saw and the circular saw improved by this method

摘要

The means of improving the target saw, the target of which includes a body equipped with peripheral cutting teeth, including rotating the saw shield, in which grooves (4a, 4b) lower than the body thickness (2) are made in the body (2) the saw (1) on both sides of its target;directed in a direction other than the radial direction, forming on the shield evenly angular rowed angular sections comprising at least part of the shield, in which the rowed sections each radial cross-section (A-A) of the shield contains at least two rows (4a, 4b) each of which lies on the other side of the shield, so that each groove is located in the body area (2),which, on the other hand, is free from the grooves.
