Use this Bear-Tex Rapid Blend silicon carbide TR (Type III) Non-Woven Quick-Change Unified Wheel with a right-angle grinder to blend and finish a wide range of materials, including aluminum, stone, tile, wood and drywall. The silicon carbide grain provides fast cutting and produces a finer, brighter scratch pattern than other abrasives. This wheel is ideal for surface generation where stock removal is not needed. Abrasive covers the entire disc, so all surfaces (the top, bottom and side of the wheel) can be used to work materials. Package of 40.
