ABSTRACT:
A disposable finishing article for mounting on a rotatable threaded spindle of 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 without 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 operative 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 pressure cap member is secured to a plurality of fingers formed on the backing flange for engaging a shoulder formed on the spindle of the power tool during operation of the finishing article.
