Claims

[Scope of utility model registration request]

An angle that continuously decreases the angle to the rake face from both ends of the intersection line toward the center of the intersection line while keeping the distance from the flank face constant to the intersection line between the rake face and the flank face. A throw-away tip in which a cutting edge ridge line having a convex curvature toward the rake face is formed on the flank by honing.
