Claims

[Scope of utility model registration request]

A plurality of chip pockets are provided on the outer periphery of the tip of the approximately cylindrical tool body, and chip mounting seats are provided on the walls facing the rotational direction of the chip pockets. In the throw-away milling tool, the main cutting edges of the throw-away chips are installed with the main cutting edges located on the outer periphery of the tool body, so that the main cutting edges of the throw-away chips are continuous peripheral edges in the rotation locus, and the tip mounting seat At least one of them has a mounting side surface facing the outer circumferential side, a mounting side surface facing the distal end side, and a mounting side surface facing the proximal end side, and the throw-away chip is mounted on this chip mounting seat. A plurality of throwaway chips are installed in parallel in the axial direction, and among the plurality of throwaway chips, the throwaway chip located on the distal side has its two sides connected to the mounting side facing the outer periphery of the tip mounting seat and the base end. The throw-away tip located on the proximal end is mounted with its two sides in contact with the mounting surface facing the outer circumference and the mounting surface facing the distal end. A throw-away milling tool that is characterized by:
