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. When a clamp screw is tightened, a nub of the clamp engages an inside rearward surface of a mounting bore of the insert with face contact and a contact pad engages a top surface of the cutting insert. As a result, the clamp exerts a force downward and rearward force on the insert. In one aspect, the nub has a polygonal cross-sectional shape.
