Offering an exceptionally fast cut and extreme durability and featuring 3M Ceramic Abrasive Grain, these discs are available in a wide selection of sizes, grits and grades to maximize work efficiency – the right tool to complete the job.Our 3M Green Corps Fibre Discs are designed to hold up to a heavy workload and are ideally suited for such applications as grinding door skins, coating removal, paint removal, gasket removal, rust and weld removal, general metal work, and clear coat applications on metal, plastic or fiberglass. These performance grinding discs are easily changeable with a rub and retainer nut design onto an appropriate grinding tool. 3M Green Corps Fibre Disc makes use of our 3M Ceramic mineral, which offers exceptional durability and improved cutting efficiency. The unique “stay sharp” crystalline structure of the ceramic grain continually generates fresh cutting edges on the surface of the workpiece, ensuring an exceptionally fast and sustained cut. The fast and uniform cutting action helps increase productivity and throughput. Additionally, the grain can withstand medium to high pressure production environments, contributing to the abrasives long service life.
