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 milling tool, which is detachably attached, the throw-away tip has a rake surface of the main cutting edge at a central portion between the tip and the rear end of the main cutting edge. A throw-away milling tool characterized by being formed with a convex curved surface so that the chip thickness is the thickest.
