Claims

[Scope of utility model registration request]

It has a polygonal shape in plan view, has an upper surface and a lower surface that are parallel to each other, and a side surface that is orthogonal to these upper and lower surfaces, and has an edge angle formed by a corner portion of at least one of the upper surface and the lower surface and the side surface. In the throw-away tip that serves as a cutting edge, each corner portion has two protruding surfaces continuous with the upper surface or the lower surface, and the ridge angle formed by each protruding surface and the side surface constitutes a cutting edge. Throwaway tip featuring.
