Abstract: A reusable mount for an abrasive device (14) including a nut (12) and a support unit (10). The nut (12) includes a threaded barrel (20) and a flange (22). The barrel extends through a central opening (15) in the abrasive device and the support unit it threadably attached by hand to the barrel to capture the abrasive device between the flange and the support unit. The assembled abrasive device and mount are then threadably secured to the spindle (70) of a power tool for use.

Abstract: A reusable mounting device which includes a support member having a support pad (32) secured to a hollow cylindrical body (42) by way of a compression ring (46). The hollow body defines a recess which receives a nut (18) that is adapted to protrude through a central aperture in an abrasive disc (1) and includes an irregular surface (22) providing an interference fit between the nut and the aperture in the disc. The nut extends into the hollow cylindrical member and includes an internal threaded bore adapted for threadable engagement with a drive member (30) which forms a part of or is attached to a portable power tool.
