Abstract
A bit holder for use in a bit assembly in road milling, mining and trenching equipment has a hollow generally cylindrical shank and first and second elongate slots positioned in spaced axial relation through the shank. The first slot extends along the shank to the distal end thereof. The second slot may be altered in length and/or shape to fine tune the outward radial force the shank exerts against the bore of a bit block into which it is inserted.
