3M Cubitron™ II 982C Precision Shaped Ceramic Grinding Disc

3M™ Cubitron™ II fiber 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. Raising the bar in abrasives This premium fiber disc raises the bar in speed and stock removal. With 3M™ precision-shaped grain, 3M™ engineers developed a process for generating triangular shaped ceramic grains that are electrostatically oriented on the backing to form sharp peaks and maximize cutting potential. These peaks act like individual cutting tools that slice through metal and continuously fracture into new sharp cutting edges.
