Abstract
A rotary cutting tool, such as a slotting cutter, includes a cutter body rotatable in a predetermined direction on a central axis perpendicular to a plane of the cutter body. A plurality of cutting insert-receiving pockets are formed at predetermined locations about the cutter body. A cantilevered member can be integrally formed in the cutter body or attached to the cutter body as a separate component. A tip of the cantilevered member at least partially extends into each insert-receiving pocket such that the cantilevered member exerts a biasing force against a cutting insert at a location so as to counteract a tendency of the cutting insert to rotate within the insert-receiving pocket during a cutting operation.
