ABSTRACT:
A hand-held driver for use with removable driving bits, such as screwdriver or nut-driver bits, is disclosed. The driver includes a handle adapted to be hand-held, and a shaft. The shaft has a proximal end secured to the handle, and a distal end with a recess sized and shaped to enable a driving bit to be insertable therein and removable therefrom with a driving end of the driving bit extending from the shaft. A retaining ring circumferentially surrounds the shaft toward the distal end and is closely sized thereto. The retaining ring has an open end adjacent to the distal end that has a size and shape corresponding to the recess in the shaft. The retaining ring enables the shaft of the driver to be constructed of lesser strength materials. The handle and shaft are constructed of a thermoplastic, and are preferably integrally constructed. The retaining ring is constructed of stainless steel or another high tensile strength material. A handle for the driver includes one or more bit-receiving slots. Each slot includes resilient means integrally molded with the handle for providing frictional resistance to movement of the bit within the slot.
