It consists of a cylindrical shank which terminates at its top in a narrow flared out head which is provided with one or more equally spaced open top and open front cavities which extend partly into the shank. Each cavity has two downwardly converging side walls and one rear wall which extends to form the floor of the cavity. A flat, usually triangular carbide cutter is inserted into each cavity and is held in position between one of the side walls and a wedge which slides within and is tightened against the carbide cutter by means of a setscrew which screws into the floor of the cavity. The invention is shown in two forms, in one of which the release of the wedge releases the pressure on the carbide cutter for replacement purposes, while in the other form the release of the wedge releases the pressure on the carbide cutter and also provides additional clearance space for the cutter to be easily replaced. | |
