• Specially designed for grinding and finishing concrete, stone, hard building materials and fiberglass • Made from extremely sharp silicon carbide grains for fast cutting and long wheel life • Manufactured by attaching multiple layers of silicone carbide to a semi-flexible fibre backing • Spiral grooves in the abrasive coating provides quick clearing of ground-off stock • Multiple cooling holes reduce the build-up of heat during grinding operations, greatly extending the life of the disc • The type 29 convex profile helps prevent gouging of the work piece and reduces operator fatigue by making it easier to maintain correct grinding angle • Mount to angle grinders using standard resin fibre disc back-up pads and nuts
