Hex Shaft Drive Arbor

摘要

A drive arbor that allows prior art abrasive pads with threaded backing to be used with impact drills and allows for a more secure connection with other rotary tools than the prior art drive arbors. The preferred embodiment of the drive arbor is an elongated metal shaft with a quick change hex shaft, a shoulder stop with flats for interfacing with a wrench and an externally threaded end for securing onto a prior art backing plate. In an alternative embodiment, the end is not threaded, and a backing plate is molded directly onto the shaft.
