Zusammenfassung:	A boring bar having a removable indexable cutting insert with a plurality of cutting edges is disclosed. The cutting insert is held in place in the bar by a locking finger on an insert clamp which is locked into place by a ball which is wedged against a release pin that engages the clamp. The ball may be moved so as to allow the pin to move, thereby releasing the force applied by the clamp whenever the insert is to be indexed or whenever a replacement of the insert is required. This is achieved by either manual or hydraulic control of a wedge shaft that engages the ball.
