Claims

[Scope of Claim for Utility Model Registration] In a clamping mechanism for a throw-away tip in which a holed tip is fixed by a clamp screw to a tip seat at the tip of a tool body having a flat tip seat bottom surface and a tip seat wall surface rising from the bottom surface. , A screw hole is provided in the chip seat, which is orthogonal to the bottom surface thereof and is an incompletely threaded portion from an arbitrary depth, and a first cavity biased toward the chip seat wall surface is provided on the bottom surface side of the chip seat of this screw hole. established,
A second cavity is provided on the bottom side of the tool body of this screw hole, which is biased toward the opposite side of the chip seat wall surface, and a fully threaded part with an effective thread count of 1 to 3 is provided between the first and second cavity. A clamping mechanism for a throw-away tip, characterized in that the clamp screw is configured so that one end of the clamp screw fits into the hole of the tip and the other end screws into the screw hole.
