Product Description ------------------- Boost productivity in your shop with the fast-cutting, long-lasting 3M Cubitron II Fibre Disc 982C. This ceramic grinding disc uses 36+ grit 3M Precision-Shaped Grain to generate up to twice the cut-rate of other fibre discs. This ceramic grain lasts exceptionally long, continuously fracturing into super-sharp points and edges that slice cleanly through metal. By grinding faster than other discs, this 3M fibre disc allows you to complete more parts and boost productivity. The built-in tinnerman nut (TN) quick change attachment allows for easy screw-on disc changes. A stiff fiber backing and strong resin bond mean this resin fibre disc is durable enough for heavyweight applications like high-pressure weld grinding and beveling. With durability comes longer abrasive life, reducing the a of time spent changing out abrasives and further boosting productivity. All of these metal grinding productivity gains come with less grinding pressure exerted by the operator. In robotic or pressure-assisted operations, 3M Cubitron II Fibre Disc 982C helps reduce downtime in the cell by lasting exceptionally long and maintaining a high cut-rate through the entire life of the disc. This 4.5 inch grinding disc can be used with either pneumatic or electric tools. 3M 982C fibre disc is optimized for use on carbon steel. For stainless steel, consider using 3M™ Cubitron II Fibre Disc 987C From the Manufacturer --------------------- The 3M™ Cubitron™ II Fibre Disc 982C with TN quick-change attachment delivers superior optimum performance and productivity with less operator igue when tackling high pressure grinding applications such as medium to heavy-duty stock removal on carbon steel applications. Featuring 3M’s exceptionally high-performing ceramic Precision-Shaped Grain (PSG) combined with a stiff fiber backing, this disc is an excellent choice for edge chamfering, beveling, and removing carbon steel welds, mill scale, pits and imperfections, machining grooves, and more. It delivers outstanding cut rates and disc life, runs cooler, and requires less grinding pressure than other conventional ceramic discs. The stiff fiber backing and strong resin bond provide added durability and tear-resistance for heavyweight applications such as high-pressure weld grinding, and support wet or dry applications. Experience the Powerful Performance of 3M™ Cubitron™ II 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 igue. To create PSG, 3M 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 like a through butter, rather than gouging or plowing as traditional abrasives 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. Disc Changes are Quicker with TN Quick Change Attachment 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. Fiber Discs—Ideal for Tough Grinding 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 hardened fibers that resist wear and can handle tough grinding applications.
