3M™ Cubitron™ II Fibre Disc 982C 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 carbon steel grinding applications such as medium to heavy-duty stock removal.
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 lasts up to two times longer than other ceramic abrasives—it 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
TN quick-change attachment simplifies disc changes between steps
Our 3M™ Cubitron™ II Fibre Disc 982C is well-suited for edge chamfering, beveling, and removing carbon steel welds, mill scale, pits and imperfections, machining grooves, and more.
Our proprietary Cubitron™ II products have raised the bar for high-performing abrasives. Our engineers started with 3M™ Ceramic Abrasive Grain and used 3M Precision Shaped Grain technology to generate triangular shaped 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 shelf-sharpen as the points break off. The grains wear evenly and self-sharpen, reducing heat due to friction for up to twice the life of other fiber discs, 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 TN attachment fiber disc has a 7/8 inch center hole that holds a thin gauge metal single-use nut, eliminating the need for a separate disc retainer nut. This TN assembly provides convenient attachment to and removal from the tool, making it easy to switch discs between applications. TN stands for Tinnerman Nut and is named after the company that originally invented this system.
