The 3M™ Cubitron™ II Fibre Disc 982C uses 3M Precision-Shaped Grain to generate up to twice the cut-rate, durability, and life of other fiber discs when grinding carbon steel — all with less grinding pressure required by the operator. That means less operator fatigue, faster throughput, and more parts per disc when tackling medium and high-pressure grinding applications. It is well-suited for edge chamfering, beveling, and removing carbon steel welds, mill scale, pits and imperfections, machining grooves, and more.
