A disposable finishing article for mounting on a rotatable threaded spindle which may be used with a power tool. The finishing article contains a retaining nut on one side and a backing flange on the other non-removably secured together on the finishing article wihtout the aid of adhesives in such a manner that the finishing article is placed in compression when it is operably secured upon the spindle of the power tool under operational 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 generally inverted cup shaped member is carried by the spindle for engaging the outer surface of the backing flange or the finishing article during operation of the finishing article.
