The Scotch-Brite™ Light Grinding and Blending Disc is a durable, non-woven course grade aluminum oxide disc that is ideal for light grinding and blending applications. It includes a backing that mounts to hook and loop pads. Make tough jobs easier. Scotch-Brite™ Discs can help you achieve a burr-free, paintable finish in fewer steps without damaging the base material. The non-woven, open-web, durable construction helps to resist loading and greatly increases the life of the disc. As a result, you will not have to change it as often.
