Abstract
A slotting cutter includes 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 cutting insert receiving pockets and a corresponding number of thread holes are formed about a perimeter of the body. A cutting insert is replaceably mounted in each insert receiving pocket of the cutter body, and a clamping screw is replaceably threaded in each thread hole of the cutter body. A cantilevered portion is disposed between each insert receiving pocket and a respective thread hole that exerts a downward force to securely hold the cutting insert in the cutter body when the clamping screw is threaded into the thread hole.

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.
