Abstract
A tool bit holder includes an inner sleeve in which a longitudinal bore is defined in which a tool bit is receivable and a detent is engageable with the tool bit for locking the tool bit within the longitudinal bore. An outer sleeve surrounds the inner sleeve and is movable relative to the inner sleeve between a locking position, in which the detent is engaged with the tool bit for locking the tool bit within the longitudinal bore, and a release position, in which the detent may be disengaged from the tool bit to permit removal of the tool bit from the longitudinal bore. A spring is positioned between the inner sleeve and the outer sleeve. The spring biases the outer sleeve toward the locking position.
