A large number of cutting blades 2, 2' formed by bending plate-shaped cutter material in contact with either the front or back surface on the peripheral edge of a disc-shaped substrate 1. The cutting edge blades 2, 2' have their tip portions protruding outward beyond either the front or back contact surfaces of the substrate, and their tips extend beyond the outer periphery of the substrate at least as far as the thickness of the substrate. The cutting edge is folded back to the opposite side from the center position and is provided with cutting edges 3 facing forward in the rotation direction, and has a symmetrical shape so that the cutting edges 3 protrude alternately from both the front and back sides of the substrate 1. A circular saw characterized in that blades 2 and 2' are arranged alternately. 2 On either the front or back surface of the disc-shaped substrate 1,
A large number of cutting blades 2, 2' made of bent plate-shaped cutting material are brought into contact and fixed to the peripheral edge, and the leading portions of these cutting blades 2, 2' extend outward from the contact surface of the substrate. A circular saw is characterized in that the tip of the circular saw is bent back toward the outer periphery of the substrate so as to protrude beyond either the front or back surface of the substrate opposite to the surface to which the cutting blade is fixed. 3 Arrange the auxiliary blade 6 on the opposite side of the cutting edge blade while sandwiching the substrate 1, and integrally fix the substrate, the cutting edge blade, and the auxiliary blade 6, and the cutting edge blade and the auxiliary blade have the cutting edge 3
The substrate 1 is lower than the cutting edge 3 in front of the cutting edge 3.
3. The circular saw according to claim 1, further comprising guard protrusions (7, 9) projecting from the outer peripheral edge of the circular saw.
