Abstract
A tool holder includes a body having a forward end with a clamp seating surface, and a clamp mounted on the clamp seating surface with an integrated insert-receiving pocket for receiving a cutting insert. The insert-receiving pocket is formed by a pair of side walls formed at an angle with respect to each other, depending on the shape of the cutting insert. A slot is formed in side walls to allow the clamp to act as a cantilevered member when a clamp screw is received in an insert screw, thereby causing the clamp to press against the cutting insert to securely hold the cutting insert in the insert-receiving pocket of the clamp.

A tool holder comprising:
- a body having a forward end with a clamp seating surface;
- and
- a clamp mounted on the clamp seating surface and having an integrated insert-receiving pocket for receiving a cutting insert.
A tool holder comprising:
- a body having a forward end with a clamp seating surface;
- and
- a clamp mounted on the clamp seating surface and having an integrated insert-receiving pocket for receiving a cutting insert, the insert-receiving pocket formed by a pair of side walls formed at an angle with respect to each other, the clamp further including a pair of opposing side walls and a slot is formed in the side walls to allow a front portion of the clamp to act as a cantilevered member,
- wherein the seating surface includes a threaded insert screw-receiving bore for receiving an insert screw and a threaded clamp screw-receiving bore for receiving a first clamp screw, the insert screw-receiving bore formed at an angle with respect to the insert screw-receiving bore, and
- wherein the clamp includes a screw-receiving bore for receiving a second clamp screw and a clamp screw-receiving bore for receiving the first clamp screw and
- wherein the second clamp screw is received in the insert screw, thereby causing the front portion of the clamp to press against the cutting insert to securely hold the cutting insert in the insert-receiving pocket of the clamp.
A method of assembling a tool holder, comprising:
- mounting a clamp with an integrated insert-receiving pocket on a clamp seating surface of a body of the tool holder such that a clamp screw-receiving bore of the clamp is substantially aligned with a clamp screw-receiving bore in the body and a screw-receiving bore in the clamp is substantially aligned with an insert screw-receiving bore in the body;
- threading a clamp screw into the clamp screw-receiving bore in the body of the tool holder;
- positioning a cutting insert between the clamp seating surface of the body and the clamp such that the cutting insert resides within the insert-receiving pocket of the clamp;
- threading an insert screw into the insert screw-receiving bore in the body, thereby causing the cutting insert to be pulled toward the insert-receiving pocket of the clamp;
- and
- threading a clamp screw into the insert screw, thereby causing the clamp to firmly engage the cutting insert and securely holding the cutting insert in the insert-receiving pocket of the clamp.
