Abstract: A rotatable seat (112) for mounting a cutting insert (114) 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 (115) through which a mounting pin or bolt is inserted and press fit into a corresponding bore (118) in a rigid base. This retains the seat in place, while allowing rotational repositioning of the seat to any desired orientation when it is not clamped down, thereby rotating the cutting insert to the selected angular orientation to the base to extend its useful life.
