ABSTRACT:
An automatic screwfeeder is adapted for use with a hand drill. The automatic screwfeeder operates to transfer uncollated screws from a screw holder into a staged position. A driving bit sequentially engages individual fasteners and drives them into a workpiece. The screwfeeder includes a front assembly separable from a rear assembly to allow replacement of the driving bit.
