ABSTRACT:
A tool for releasably supporting a length of abrasive strip material in a generally cylindrical coil with its abrasive surface out and for transferring torque from a drive chuck to rotate the coiled strip about its axis so that the outer surface of the strip may be used to abrade a workpiece. The tool includes a body member including a driven end portion adapted to be engaged by the chuck, a cylindrical central transfer portion, and a cylindrical supporting end portion about which the inner surface of the coiled length of abrasive strip material is supported. A coil spring has one end portion which fits closely about the outer surface of the transfer portion and an opposite end portion which engages the outer surface of the coiled length of abrasive strip material both to hold it in place and to transfer torque to it from the driven body member.
