チツプ。 It has a generally elliptical plate shape in appearance, and an arc-shaped cutting edge and a linear small cutting edge intersecting the end of this cutting edge are formed on the ridgeline of the upper surface, which is the rake surface. The entire rake face along the small cutting edge and the edge of the cutting edge gradually approaches the lower surface side from the center side of the throw-away tip toward the small cutting edge, and A throw-away tip characterized in that it is formed by a concave surface that gradually approaches the bottom side toward the center between the cutting edge ends.
