Constructed with a long-lasting zirconia grain that delivers efficient cutting, the all-purpose Metal R828 coarse grit center mount fiberglass conical flap disc is intended for use with a right angle grinder. Rely on the disc for stock removal, deburring, beveling and blending on a range of metals including, 300 and 400 series stainless, super alloys, cast iron, and soft carbon. To allow for optimal surface contact, the disc features angled polyester and cotton flaps. Lightweight fiberglass and resin backing plates reduce vibration for comfortable use.
