Description:

Abstract:

The specification discloses a cutting tool (10) having a cutting insert (18) mounted thereon. A clamp (20) is secured to a tool body (12) by a screw (24) and spring (62) interconnection, and a clamp tip (22) extends from the clamp (20) towards the insert (18). Structure, such as a groove (25) or shoulder (82), is formed in or on the upper surface of the cutting insert (18) for interengaging with the clamp tip (22) to secure the cutting insert on the cutting tool (10). Lateral shoulders (30) and (32) and a body surface (52) engage and align the insert (18) thereby, preventing lateral, rearward, and rotational movement of the insert (18).
