The 7” x ⅞” Semi-Flex Disc is an abrasive solution engineered for fast, aggressive material removal on hard, mineral-based surfaces. Built with extra-coarse 36 grit silicon carbide and a red fiber semi-flex backing, it delivers rapid cutting performance while maintaining control on uneven or contoured areas. The domed profile improves grinding angle and surface contact, making it ideal for demanding applications like concrete, stone, terrazzo, and fiberglass work.
