Patent ID: 8647023

Claim:
A slotting cutter, comprising: a disc-like cutter body rotatable in a predetermined direction on a central axis perpendicular to a plane of the cutter body; a plurality of insert receiving pockets formed about a perimeter of the body; a plurality of thread holes formed about the perimeter of the cutter body, each thread hole extending radially inward from the perimeter of the body toward the central axis; a clamping screw replaceably threaded in each thread hole of the cutter body; a cantilevered portion disposed between each insert receiving pocket and a respective thread hole; and a slot extending from the thread hole and into the cantilevered portion to prevent unwanted movement of the cutter body when the clamping screw is threaded into the thread hole, a portion of the slot extending substantially parallel to the thread hole, wherein the clamping screw causes the cantilevered portion to exert a downward force against a cutting insert when the clamping screw is threaded into the thread hole.
