Claims

[Scope of Claim for Utility Model Registration] It has a substantially rectangular parallelepiped shape, and its lower surface serves as a seating surface that comes into close contact with the tip mounting seat of the tool holder, and
A throw-away chip in which a front cutting edge is formed on the ridge line between the upper surface serving as the rake face and the end face serving as the front flank surface, and a cross cutting edge is formed on the ridge line between the side surface serving as the side flank surface and the above-mentioned upper surface. The throw is characterized in that the cross-cutting blade is formed in a concave-convex curve shape that alternately repeats concavities and convexities from the tip side toward the rear end side when viewed from the side in a direction perpendicular to the side surface. Away tip.
