Claims

[Scope of Claim for Utility Model Registration] A chip in the shape of a polygonal flat plate, each end face of which is sloped so that its cross section is approximately trapezoidal with the seating surface as its base; and a chip that engages with the seating surface of the chip. A tool holder equipped with a tip mounting groove comprising a mounting surface to be fitted together, and a projecting wall that bulges along the mounting surface and locks at least one end surface of the tip; a clamp piece provided opposite to the projecting wall, the seating surface of the chip and at least one end surface being engaged with the mounting surface of the chip mounting groove and the projecting wall, respectively; , the other end surface of the chip facing the clamp piece is pressed toward the projecting wall by the clamp piece, so that the seating surface of the chip is pressed against the mounting surface of the chip mounting groove. In the clamp bit, the contact position between the end face of the tip and the protruding wall of the chip mounting groove is set at a position closer to the seating surface of the chip than the contact position of the clamp piece with the other end face of the chip. A clamp bite that is characterized by:
