3M™ Finesse-it™ Roloc™ Finishing Disc Pad is made with soft foam to provide greater conformability than standard 3M™ Roloc™ backup pads. The 3M™ Hookit™ surface is manufactured with mushroom headed hooks that hold the buffing pad firmly in place. This backup pad is designed to be used with rotary tools only. The foam backing provides good conformability.
