3M Cubitron II Fibre Disc 982C offers optimum performance and productivity on carbon steel with our exceptionally high-performing 3M Precision Shaped Grain combined with a stiff fiber backing, and generates up to twice the cut-rate, durability, and life of other fiber discsall with less grinding pressure.

Designed for carbon steel applications, 3M Cubitron II Fibre Disc 982C delivers superior throughput with less operator fatigue when tackling high pressure grinding applications such as medium to heavy-duty stock removal, delivering a lower cost per grind with fewer steps in the grinding sequence. This disc is well-suited for edge chamfering, beveling, and removing carbon steel welds, mill scale, pits and imperfections, machining grooves, and more.Our proprietary 3M Cubitron II products have raised the bar for high-performing abrasives. Our engineers started with 3M Ceramic Abrasive Grain and used precision shaped grain technology to electrostatically orient each triangular structure on the backing to form sharp peaks and maximize cutting potential. These peaks act like individual cutting tools that slice through metal, and continuously shelf-sharpen as the points break off. The grains wear evenly and provide extra-long life and consistency with less grinding pressure. The result is that Cubitron II discs outcut and outlast every conventional ceramic industrial abrasive disc on the market, maximizing productivity and minimizing operator fatigue.Fiber discs are heavy-duty discs ideal for weld removal, grinding, and blending large and small areas of metal surfaces. They feature a tough, stiff backing made from hardened fibers that resist wear and can handle tough grinding applications. A center hole disc is attached to a disc pad hub and face plate with a compatible disc retainer nut, and mounted on a right angle grinder (all sold separately).

3M Precision Shaped 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

Triangular-shaped ceramic grain 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 can be used wet or dry

7/8" center hole mount is compatible with 3M Disc Pad Face Plates and Hubs, and requires the use of a disc retainer nut (all sold separately)
