Abstract
A cutting assembly includes a holder and a cutting tool body mounted in a bore of the holder, and a retainer sleeve for retaining the tool body axially within the bore while permitting the tool body to rotate freely about a longitudinal axis thereof. The retainer sleeve includes inwardly bent tongues which engage a groove formed in a shank of the tool body. The retainer sleeve is configured to facilitate the escape of fines from the groove during a cutting operation.
