Claims

[Scope of utility model registration request]

In a throw-away tip which has a plate shape with a circular outer periphery and has a cutting edge formed on the outer periphery of the upper surface, there is a V-shape reaching from the upper surface to the lower surface at a position dividing the circumference of the outer periphery into three equal parts. A notch is formed in the shape of a shape, and the intersection between the wall surface of the notch located on the tip side of the cutting edge and the top surface is formed by a plurality of continuous sloped surfaces each inclined at a different angle with respect to the top surface. A throw-away tip characterized by being formed with a straight line.
