3M Green Corps Discs are designed to handle heavy workloads and are ideally suited for applications like grinding door skins, coating removal, paint removal, gasket removal, rust and weld removal, and clear coat applications on metal, plastic, or fiberglass. These performance grinding discs are easily changeable with a rub and retainer nut design on an appropriate grinding tool. The sanding discs use 3M's ceramic abrasive grain, which offers exceptional durability and improved cutting efficiencies. The unique "stay sharp" crystalline structure of the ceramic grain continually generates fresh, uniform cutting edges on the surface of the work piece, ensuring a fast and sustained cut. Additionally, the grain can withstand medium to high-pressure production environments, contributing to the abrasive's long service life.
