Claims

[Scope of utility model registration request]

In a throw-away chip that has a regular polygonal plate shape with a flat lower surface serving as a seating surface and a main cutting edge formed on the ridgeline portion of the upper surface, an imaginary line connecting the centers of the opposing ridgeline portions of the upper surface. A top part where the thickness between the upper and lower surfaces is the maximum is formed in the top surface, and a valley part where the thickness is the minimum is formed in the diagonal part connecting the opposing corner parts of this top surface, and these top parts adjacent to each other are formed. and a trough are continuous on an inclined surface in which the thickness between the upper and lower surfaces gradually decreases from the top to the trough.
