Claims

[Claims for Utility Model Registration] It has a substantially rectangular plate shape in appearance, with a mounting hole penetrating through the center of the upper and lower surfaces, and the above-mentioned mounting hole on the side surface located between the upper and lower surfaces. In a throw-away chip in which a ridgeline parallel to the axis of the main cutting edge is the main cutting edge, and a side cutting edge is formed at the ridgeline where the rake face of the main cutting edge intersects with the upper and lower surfaces, a pair of the above-mentioned edges that are not adjacent to each other are used. A ridgeline at both end portions of the side surface that forms a rake face of the main cutting edge and is sandwiched between the pair of side surfaces and serves as a front clearance surface of the main cutting edge, and a ridge line where the upper and lower surfaces intersect. A chamfer part having a width in the range of 0.5 mm to 1.5 mm is formed over the entire length, thereby forming a chamfer part between the main cutting edge and the side blade. Throwaway tip.
