3M 66779, Cubitron II Roloc Fibre Disc 982C, 36+, TR, Red, 3 in, Die R300V, 7000118430, 200 per case

Engineered for tough durability, faster results, and increased throughput, our 3M Cubitron II Roloc Fibre Disc 982C is constructed with 3M’s exceptionally high-performing ceramic Precision-Shaped Grain (PSG), resin-bonded to a stiff fiber backing. Choose the Cubitron II Roloc Fibre Disc 982C for medium to heavy-duty stock removal on carbon steel applications such as edge chamfering, beveling, weld grinding, and removing mill scale, pits and imperfections, machining grooves, and more.

3M Cubitron II products have raised the bar for high-performing abrasives. 3M precision-shaped grain outcuts and outlasts conventional ceramic industrial abrasives and requires less grinding force to achieve superior performance. The result is that operators can grind faster and complete more parts per disc with less muscle-work and fatigue.

To create PSG, our engineers started with 3M Ceramic Abrasive Grain and used proprietary technology to form the grains into triangular structures and electrostatically orient them on the backing to form sharp peaks that maximize cutting potential. These peaks slice cleanly through metal, rather than gouging or plowing as traditional abrasive grains do, and continuously self-sharpen as the points break off. This generates a super-fast cut and lessens heat build-up due to friction, reducing heat-related stress cracks and discoloration.

PSG also wears evenly, and because the abrasive itself stays cooler and sharper, Cubitron II products last significantly longer than their conventional ceramic counterparts, ensuring extended high performance in production applications.

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 vulcanized fiber that resist wear and can handle tough grinding applications. When the work surface calls for the use of a smaller disc for stock removal, Roloc fiber discs provide an effective solution.

3M Cubitron II Roloc Fibre Disc 982C is available for use with the following attachment systems: TR, TSM and TS. Please select discs with the attachment design made for your system.
