When you need a coarse finishing wheel for cleaning and deburring, the 25-pack of Shark Industries Brown Quick Change Surface Prep Discs delivers performance. Each conformable, non-woven disc features a Type R quick-change locking system that is easily attached to the backing pad. Swap out an old disc quickly and get back to work. Equivalent to 3M #07480. Use with right-angle and die grinders. Pair them with the PN-13012 twist-to-lock rubber backing pad from Shark for the best performance. We assemble our brown “cookies” in the United States, so customers can trust the quality.
