Claims

[Scope of utility model registration request]

The indexable tip is provided with a bolt insertion hole whose diameter gradually decreases from the top to the bottom, while the tip seat of the tool body to which the indexable tip is attached is
A flat bottom surface that contacts the lower surface of the throw-away chip, and a wall surface that stands up at the rear end of the bottom surface so that the side surface of the throw-away chip contacts, and a screw hole that corresponds to the bolt insertion hole is formed in the bottom surface. A clamping mechanism for a throw-away tip that screws a convex-away tip onto a tip seat using a threaded member passed through the bolt insertion hole, wherein the screw hole is used to secure a holster of the indexable tip positioned on the tip seat. a protruding portion whose central axis is eccentrically provided toward the wall surface with respect to the insertion hole, and the screw member presses the inner periphery of the bolt insertion hole on the wall surface side and presses the indexable tip against the bottom surface of the chip seat and the wall surface; and a flange that presses down on the top surface of the throw-away tip, and the flange is in a position separated from the top surface of the throw-away tip when the protrusion begins to come into contact with the bolt insertion hole, and is further screwed into the throw-away tip. A clamping mechanism for indexable tips that is characterized by contacting the top surface of the tip.
