Claims

[Claims for Utility Model Registration] A throw-away chip that has a polygonal plate shape and has main cutting edges formed on at least one pair of opposing ridges on its upper surface, wherein the upper surface intersects with the main cutting edges. and draw a concave curve symmetrical to the center in a cross-sectional view along one reference line passing through the center of the upper surface,
A throw-away chip characterized in that it is formed with a curved surface that draws a convex curve symmetrical with respect to the center in a cross-sectional view along another reference line that is perpendicular to the first reference line and passes through the center of the upper surface.
