Claims

[Scope of utility model registration request]

A groove extending approximately in the axial direction of the tool body is formed on the outer periphery of the tip of the tool body, a tip holder is crimped and fixed to the bottom of this groove, and a throw-away tip is attached to the tip mounting surface formed at the tip of the tip holder. In the throw-away milling tool, the tip mounting surface or the contact surface of the tip holder with the bottom surface of the groove is located in the direction of the rake of the throw-away tip with respect to the axis of the tool body. A throw-away milling tool, characterized in that the groove is inclined in a direction that gives a predetermined axial rake to the surface, and the bottom surface of the groove is parallel to the axis of the tool body.
