Abstract
A metal cutting tool comprising a tool holder and a double sided cutting insert is disclosed. 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 insert is retained by the tool holder via a shim, substantially corresponding in shape and lateral dimensions to the insert. The shim has a 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.
