Cutting insert mounted on holder by rib-and-groove coupling

摘要

A cutting insert is mounted by a rib-and-groove connection on a holder. The grooves are formed in a bottom surface of the insert, and the ribs extend from a holding surface of the holder. The ribs and grooves include mutually convergent sides configured such that a gap is formed between the holding surface and bottom surface, and between a top of each rib and a bottom of a respective groove.
