<p>An abrasive grinding or finishing device mounting assembly which includes a hub cap (18) which is retained upon the threaded spindle (14) of a power tool (10). A hub (26) is permanently affixed to the abrasive device without the use of adhesives and is discarded when the abrasive device is spent while the hub cap is retained on the spindle for reuse. The hub includes a lower radially outwardly extending flange (38) adapted to engage the front surface of the abrasive device and a barrel which extends upwardly from the flange and through an opening in the abrasive device with the outer periphery of the barrel forming an outer rim (120) which is adapted to be formed into engagement with the back surface of the abrasive device to thereby secure the hub permanently to the abrasive device.</p> |
