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 cutter body along one circumference thereof with a positive installation inclination angle corresponding to a positive axial rake angle, The throw-away tip has main cutting edges formed on opposing ridges of its upper surface, and
It has a rectangular plate shape with a rake face formed on the side surface from the main cutting edge to the lower surface serving as the seating surface, and the rake face along the main cutting edge is the width between the rake faces at the center of the main cutting edge. A throw-away milling tool, characterized in that it is formed with a convex curved surface whose dimension is larger than the width between the respective rake faces at the tip and rear end of the main cutting edge.
