ABSTRACT:
A hand tool includes a rotatable bit cartridge for holding a plurality of stored bits and a retractable shaft that extends from a housing of the hand tool. A distal end of the retractable shaft includes a bit holder for holding a bit. Retracting the shaft within the housing of the tool causes the bit to be ejected from the distal end of the shaft and transported through an opening in the tool housing to the rotatable bit cartridge. The bit cartridge is then rotated to retrieve another bit and the shaft is then extended to transport the new bit through the opening in the housing and into alignment with the bit holder of the shaft. The shaft is further extended to engage the bit and extend the bit to an operative position outside of the tool housing. Example hand tools include a screwdriver and a power drill.
