3M™ Cubitron™ II fiber disc 982C slices through carbon steel with 3M™ precision shaped grain and generates up to twice the cut rate, durability and life of other fiber discs - all with less grinding pressure. That 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. 3M™ Cubitron™ II fiber disc 982C is well-suited for edge chamfering, beveling and removing carbon steel welds, mill scale, pits and imperfections, machining grooves and more.
