Abstract:
[OBJECT] To make tips less likely to be damaged. [MEANS OF REALIZING THE OBJECT] A tip (30) has a first rake face (40) that is contiguous with a cutting edge (32), and a second rake face (42) that is contiguous with the first rake face and faces a gullet (16) provided in front of the tip (30) in the rotational direction, wherein the second rake face (42) has a radially inward inner edge that is in contact with the outer peripheral edge of the base metal (12) that defines the gullet (16). The second rake face (42) is formed such that the second rake angle (¸2), which is formed between a first reference line (L1) drawn from the rotation center of the circular saw blade to the cutting edge (32) and a second reference line (L2) that passes through the radially inward inner edge along the second rake face (42), is a negative angle.
