Abstract
A bit holder for a cutting tool utilizes a non-rotatable sleeve which is slit its entire length axially and is force-fitted into the bore of the bit holder. The sleeve is removable in the field and provides protection for the bit holder. In an alternate embodiment the sleeve is provided with additional retaining means in the form of a circumferential flange which extends beyond the bit holder and contacts the rearmost portion thereof.
