Sanding Pad. Just one more secret from the Evan's arsenal.
The sanding pad for grinder is what we use for "Scraping" or heavy removal on aluminum and stainless. These sanding backing pads are hook and loop style with a 5/8"-11 threaded to fit on most variable speed and full speed grinders. The backing pad has a foam backing to help be a lot more forgiving when sanding on an edge or flat.
