ABSTRACT:
A tool having a handle and including a sleeve and a spring is provided which is simple and cost effective to manufacture. The sleeve is provided with a slot and the spring is positioned so that a portion of the spring extends through the slot. The sleeve is positioned in a bore in the handle. A removable, reversible bit is held in the handle by the sleeve and the spring. The spring applies sufficient force to the bit to retain the bit within the handle. The sleeve also prevents the bit from rotating relative to the handle. The bit may be removed from the handle by pulling the bit away from the handle. The same end of the bit, another end of the bit, or a different bit may be reinserted in the handle.
