Cutting tool assembly including retainer sleeve with compression band

摘要

A cutting tool assembly for mounting in a bore of a holder includes a cutting tool having a head, a shank and a collar therebetween having an axially rearward surface that defines an annular channel adjacent an axially forward end of the shank. The assembly also includes a retainer sleeve substantially surrounding the shank and defining a slot that extends from an axial forward end to an axial rearward end of the retainer sleeve. The retainer sleeve is compressible between an expanded state and a compressed state. The assembly further includes a compression band removably attached to the retainer sleeve. The compression band in a first position is attached to the retainer sleeve and compresses the retainer sleeve to the compressed state and in a second position is not attached to the retainer sleeve and the retainer sleeve is in the expanded state.
