A rotary finishing device includes a generally circular hub having a front surface, a back surface, an inner periphery and an outer periphery. The inner periphery of the device defines a throughhole. The front surface of the hub has a plurality of slots formed therein. Each of the plurality of slots has a plurality of finishing sheets secured therein by an adhesive. Each of the finishing sheets is of sufficient length such that when the generally circular hub rotates at a slower speed, the plurality of sheets remain within the outer periphery of the generally circular hub and provide a relatively flexible device for contacting a surface to be finished. Further, when the generally circular hub rotates at a higher speed, the plurality of sheets extend beyond the outer periphery of the generally circular hub and provide a relatively stiff device for contacting a surface to be finished.
