Appl. No.:
09/616522
Inventors:
David A. Rigotti - Chesterland OH
Gregory J. Lavoie - Farmington CT

Abstract:
A broach comprises an elongate body having a plurality of longitudinally spaced pockets therein. A threaded hole is provided in each of the pockets. The pockets are adapted to receive cutting inserts. The cutting inserts have a hole that is adapted to align with a hole in the pockets. The aligning holes are adapted to receive insert screws. The insert screws are threadably received in the threaded hole in the pockets. When a cutting insert becomes worn or damaged, it may be removed from its pocket and replaced with another cutting insert. Hence, the broach need not be discarded because of a worn or damaged cutting insert.
