Claims

[Scope of utility model registration request]

A polygonal plate-shaped chip such as a rhombus or a rectangle has a cutting edge composed of a flank and a land on the upper surface or the upper and lower surfaces, and the land is narrower in the nose portion than the land formed in the straight portion. In addition, a pair of semicircular protrusions are provided in the groove near the nose, and a flat part is formed higher than the land in the center of the chip, and a protrusion bulges toward the nose and a straight land toward the nose. 1. A throw-away chip characterized in that a wavy bulge is formed in the groove that becomes larger as the distance from the groove increases.
