Work efficiently with this Merit A/O fine grit TR (Type III) non-woven quick-change buffing disc on your right angle grinder. This fine-grit aluminum oxide disc features a resin bond that produces a smooth cut rate so you can buff evenly and without smears. Laminated non-woven nylon fibers and a nylon backing provide a durable base for the abrasive and resist tears, even when grinding burrs or sharp edges. Designed for light removal of rust, coatings or oxidation, the disc works well with steels, super alloys, soft metals and non-ferrous materials, such as fiberglass and composites.
