Claims

[Scope of utility model registration request]

In a throw-away milling tool in which a throw-away tip is removably attached to the outer periphery of the tip of the tool body along one circumference, the throw-away tip is a cutting edge located on the outer periphery of the tool body. is the main cutting edge, and the rake face of the main cutting edge is formed with a convex curve so that the chip thickness is the thickest at the center between the cutting edge tip and the rear end of the main cutting edge. A throw-away milling tool characterized by:
