ABSTRACT:
A tool assembly includes an axially symmetric tool having a tapered forward end, a radial flange, and a cylindrical shank. A retainer is fitted around the cylindrical shank, a washer is fitted around the retainer, and an annular elastomeric member is bonded to the inner surface of the washer. When the rotatable shank is fitted into a cylindrical mounting bore of a tool holder, the annular elastomeric member prevents the washer from rotating with the tool.
