Claims

[Scope of utility model registration request]

It has an approximately elliptical plate shape in appearance, and has an arc-shaped cutting edge on the ridgeline of the upper surface, which is the rake face, and a linear small cutting edge that intersects the end of the arc-shaped cutting edge at an obtuse angle. , and the entire rake face along the small cutting edge and the edge of the cutting blade is formed by a convex curved surface that gradually approaches the lower surface side from the center side of the throw-away tip toward the small cutting edge side. A throw-away tip, characterized in that a round honing is formed in a portion of the arc-shaped cutting edge portion along the convex curved surface, and a chamfer honing is formed in the other portion.
