ABSTRACT:
A clamping tool holder includes a tool holder body and a clamp for clamping a cutting insert. The clamp causes the cutting insert to press against the bottom and the side walls of an insert-receiving pocket of the tool holder body. The tool holder body has an inclined surface sloping inward in a direction away from the insert-receiving pocket. The clamp has an inclined surface that acts as a ramp with the inclined surface of the tool holder body. A guide pin prevents the clamp from twisting during tightening or loosening of the clamp. When a clamp screw is tightened, a nub of the clamp engages only an inside rearward surface of a mounting bore of the insert along a line of contact and the top surface of the cutting insert. In addition, only a forward lower face of a head portion of the clamp screw engages a top surface of the clamp.
