Claims

[Scope of utility model registration request]

A throw-away tip having a mounting hole is placed on the chip seat of the tool body, a clamp screw is inserted into the mounting hole, and the clamp screw is screwed into the screw hole formed in the tool body. In the throw-away tip clamping mechanism for fixing the throw-away tip to the tool body, the outer end of the clamp screw is formed with a head having a first flat surface on its lower surface; A first conical surface whose cross-sectional area becomes smaller toward the distal end along the axis of the clamp screw is formed in series with the clamp screw, and near the opening edge of the hole for mounting the throw-away tip, A second conical surface is formed that the first conical surface closely contacts, and a second flat surface that is connected to the second conical surface and that the first flat surface closely contacts. A clamping mechanism for a throw-away tip, characterized by the following:
