Abstract
A shim for use in a metal cutting tool comprised of a tool holder and a double sided cutting insert. The insert has rake surfaces formed in the corners of upper and lower surfaces of the insert with a recess formed in the corners. The shim is used to retain the insert in the tool holder. The shim has a shape and lateral dimensions substantially corresponding to the insert. The shim has at least one projection which mates with the recess. When the insert and shim are clamped in the tool holder, the projection adjacent an operative pair of insert cutting edges bears against the walls of the associated recess, effectively supporting the insert in this region. This results in the inoperative lower cutting edges being spaced from the shim.
