Claims

[Scope of utility model registration request]

A throw-away tip is placed on a tip seating section provided on the outer periphery of the cutter body, and the throw-away tip is held in a wedge-shaped clamp whose axis is inclined at a predetermined angle with respect to the top surface of the throw-away tip. In the throw-away type cutter, which is detachably fixed to the tip seating portion by a screw and a wedge member which is movable in the axial direction by the clamp screw, the throw-away tip is attached to a side wall of the wedge member. Forming a stepped portion protruding in three directions, the upper surface side, the wall surface side of the cutter body located on the opposite side of the upper surface, and the wall surface side facing the tip side of the cutter body and abutting on each wall surface, and on the clamp screw, The wedge angle is provided by tilting the clamp screw in a substantially rotational direction of the cutter body with respect to the upper surface of the throw-away tip, and the clamp screw is shifted toward the proximal end of the cutter body with respect to the throw-away tip. A throw-away cutter that is characterized by its placement.
