The 3M™ Green Corps™ Cut-Off Wheel is designed to provide high cut rates and long life on a variety of materials, including fibreglass, stainless steel, mild steel and aerospace alloys. Ideal for use on a wide variety of utility type cut-off tools. Do not use on tools without guards. The 3M™ Green Corps™ Cut-Off Wheel is a durable, fast-cutting wheel used on almost all materials, including fibreglass, stainless steel, mild steel, and aerospace alloys. Constructed with 3M™ High-Performing Ceramic Abrasive Grain, these wheels out cut and outlast aluminum oxide wheels. The combination of high speed rating and 3M ceramic abrasive grain content means a cool, sharp, quick cut with minimal product wear. Wheel must be attached to a cut-off wheel power tool designed specifically for the size of wheel used. Unlike abrasive discs, which shape or sand objects using the disc surface, cut-off wheels provide perpendicular grinding, using the outer edge of the wheel. Abrasive cut-off wheels are typically used for cutting through metal, for example auto body or marine sheet metal, stainless steel tubing, exhaust pipes, clamps, and rusted fasteners. Cut-off wheels are attached to a cut-off tool (sold separately) and must always be used with a wheel guard for safety.
