Claims

[Scope of utility model registration request]

A plurality of indexable tips, each having a cutting edge on the outer periphery side as a main cutting edge, are disposed on the outer periphery of the tip of the tool body, and the main cutting edges are connected to each other in the axial direction of the tool body in their rotation loci. In the throw-away type milling tool which is detachably attached to the throw-away chip, the rake face of the main cutting edge of the throw-away chip extends from the center of the upper surface of the throw-away chip toward the main cutting edge between its upper and lower surfaces. 1. A throw-away milling tool, characterized in that it is formed of an inclined surface whose thickness gradually increases, and a curved surface that forms a smooth convex curved surface along the main cutting edge.
