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. Well-suited for edge chamfering, beveling, and removing carbon steel welds, mill scale, pits and imperfections, machining grooves, and more.
