<p>A multi-bit driver comprises a housing and a plurality of bit assemblies operatively retained within the housing. At least one of the bit assemblies has a base portion and a tool bit member removably and replaceably mountable on the base portion. A bit chuck in the housing is for receiving each tool bit member singularly in torque transmitting relation, and includes a bit- receiving opening for permitting each tool bit member singularly to extend therethrough. The housing includes a substantially transparent forward portion that permits viewing of the tool bit members. An actuator extends from each bit assembly exteriorly to the housing for operative engagement by a user, for cooperative movement of the actuator means and the bit assembly between a retracted configuration, a forwardly extended in-use configuration.</p> |
