Abstract
A multi-size tool bit holder includes a first sleeve having a first bit holding bore extending along an axis, and a second sleeve coupled for co-rotation with the first sleeve and movable relative to the first sleeve between a first position and a second position. The second sleeve includes a second bit holding bore. A first bit shank of a first nominal size is insertable into the first bit holding bore when the second sleeve is in the second position to secure the first bit shank within the first sleeve. A second bit shank of a second nominal size different than the first nominal size is insertable into the second bit holding bore when the second sleeve is in the first position to secure the second bit shank within the second sleeve.
