To be used with right angle grinders 3M Precision Shaped Ceramic Grain maintains super-sharp points that cut exceptionally fast with less pressure Disc life is significantly longer, completing more parts per disc and requiring fewer disc changes These discs lasts up to two times longer than other ceramic abrasives— wears evenly, runs cool and optimizes mineral breakdown Stiff fiber backing and a strong resin bond provide durability and tear-resistance for heavyweight applications such as high-pressure weld grinding and beveling 3M™ Cubitron™ II Fibre Disc 982C slices through carbon steel with 3M Precision Shaped Ceramic Grain and generates up to twice the cut-rate, durability and life of other fibre discs—all with less grinding pressure. This means less operator fatigue, faster throughput and more parts per disc when tackling high pressure grinding applications such as medium to heavy-duty stock removal.
