ABSTRACT:
A screw fastened clamping neck attachment for an electrical hand operated drill. The electrical motor of the drill is of the neckless type and has a short rotary shaft extending from the housing. The screw fastened clamping attachment is in the form of two semi-cylindrical bushings adapted to be clamped together at their base portion to form a neck, these bushings, in clamped condition, encasing an extension shaft therebetween which is to be connected to the short shaft of the electrical motor. Preferably the extension shaft has a connecting sleeve end threaded internally with the short shaft threaded externally to provide a threaded connection. Bearings are provided for the extension shaft of the attachment within the semi-cylindrical bushings. Fastening arms extend rearwardly from the bushings to support the attachment on the housing and to resist torsion.
