Abstract

A rotatable seat for an insert of a machine tool that has a clamp for holding the insert securely in place during the machining operations. The seat has a substantially cylindrical body that includes a longitudinally extending throughbore, and a first end and a second end. The first end has a v-shaped trough that is sized to receive the v-shaped back end of an indexable (or other type) of insert. The second end of the rotatable seat is sized and shaped for seating flush against a back end of the clamp of the cutting tool. A press fit, or other fastener, extends through the throughbore of the seat body into a bore in the back end of the clamp and the seat is able to rotate about the fastener. The seat is positioned at and angular orientation and the insert is then fitted in the v-shaped trough in the seat in a corresponding angular orientation. These two components as assembled together and held in place by tightening the clamp fastener. By periodically loosening the clamp and rotating the insert, as the cutting edge is worn, fresh cutting edge is exposed. The rotation thereby prolongs the useful life of the insert.
