A finishing article comprising a backing member defining a central opening and having two opposed surfaces each carrying an abrasive material thereon; an intermediate member, having a central bore therethrough, being positioned in the opening and attached to the backing member, the central bore is capable of being at least partially threaded for supporting the finishing article to a support member. The partially threaded bore of the finishing article is detachably connectable to a threaded portion of a support member to provide rotational movement from the support member to the finishing article for finishing an object wherein the partially threaded portion of the central bore lies substantially in the plane of the backing member so that both abrasive surfaces of the finishing article can be used for abrasive sanding and, if desired, the abrasive surfaces of the article can carry different grades of abrasives.
