摘要
A disposable depressed center grinding wheel for mounting on a rotatable threaded spindle of a power tool. The grinding wheel contains a retaining nut on one side and a backing flange on the other non-removably secured together on the grinding wheel without the aid of adhesives in such a manner that the grinding wheel is placed in compression when it is operably secured upon the spindle of the power tool under grinding loads. The nut and flange are secured together by upsetting one end of the nut causing it to protrude outwardly over the outer surface of the flange. A base member is loosely secured to the spindle of the power tool for engaging the outer surface of the backing flange during operation of the grinding wheel.
