Claims

[Claims for Utility Model Registration] A throw-away machine having a polygonal shape with parallel upper and lower surfaces, a main cutting edge being formed on each side of the upper surface, and a minor cutting edge being formed between each main cutting edge. In the uchip, the upper surface along the main cutting edge is formed by a convex curved surface such that the thickness between the upper and lower surfaces at the tip of the cutting edge of the main cutting edge is thicker than the thickness at the rear end of the cutting edge of the main cutting edge. At the same time, the surface between the cutting edge rear end of one main cutting edge and the cutting edge tip of another main cutting edge adjacent to this one main cutting edge is the cutting edge rear end of the one main cutting edge mentioned above. The thickness gradually increases in the direction intersecting this main cutting edge and extends to the cutting edge tip of the other main cutting edge, and the ridge line is formed by an inclined surface that is the width cutting edge. Features a throw-away tip.
