Claims

[Scope of Claim for Utility Model Registration] A tip mounting seat with a plurality of mutually opposing wall surfaces is formed on the periphery of a substantially disc-shaped cutter body, and a polygonal throw-away tip is attached to the tip mounting seat. By inserting a wedge member between the throw-away tip and the wall surface of one of the tip mounting seats from a direction perpendicular to the axial direction of the cutter body, the throw-away tip can be attached to the other wall of the tip mounting seat. In the chip clamp mechanism configured to press and fix the chip toward the wall surface, on the contact surface between the chip mounting seat and the wedge member,
A groove and a convex portion extending in the insertion direction of the wedge member and engaging with each other are formed, and a contact surface between the wedge member and the throw-away chip and a contact surface between the chip mounting seat and the throw-away chip. A tip clamp mechanism characterized in that a groove portion and a convex portion are formed which extend in the insertion direction of the throwaway tip and engage with each other.
