3M™ Cubitron™ II Fibre Disc 987C offers significant gains in productivity on medium to heavy-duty operations with high-performing 3M Precision Shaped Grain combined with a stiff fiber backing. This disc achieves a higher cut-rate, greater durability, and longer life than other fiber discs—all with less grinding pressure. Use 3M™ Cubitron™ II Fibre Disc 987C to generate exceptionally high cut-rates with less pressure, allowing operators to finish tough tasks with minimal fatigue. Our heavy duty discs are ideal for weld removal, bevelling, grinding and blending. A grinding aid on the disc makes this an outstanding product for all types of metal. It helps keep the disc cooler on stainless steel and heat sensitive metals such as nickel alloys and titanium, reducing metal discolouration and oxidation as well as the chance of heat related stress cracks. This means our discs can outlast and out-cut rival products. They contain 3M Precision Shaped Grain which forms into triangular points that slice through metal rather than gouging or ploughing like traditional abrasives. These points continuously self-sharpen as they fracture, generating an extremely fast cut. Our discs feature a tough, stiff backing made from vulcanized fibre that resists wear and can handle tough grinding applications. They’re ideal for removing mill scale, pits and imperfections

3M™ Fibre Disc 787C is a fibre disc featuring our advanced abrasive technology, 3M Precision Shaped Grain. These discs have a stiff fibre backing and strong resin bond that provide durability and tear resistance. They’re constructed with a grinding aid and are engineered for ultra-rapid cut.Use 3M™ Fibre Disc 787C for a step up in performance over conventional fibre discs. Our fibre discs offer an ultra-fast cut making them an excellent choice for weld removal, blending, and finish refinement on stainless steel and high nickel alloys. The advanced solution for challenging applications Balance cost and output by selecting the abrasive with precisely the right amount of cut and life. 787C contains the exact amount of precision shaped grain (PSG) you need to optimise the balance of speed and longevity for challenging applications from grinding to deburring. A grinding aid is incorporated to keep the disc and workpiece cool and further prolonging disc life. Disc construction includes a stiff fibre backing and strong resin bond that provide durability and tear-resistance. This combined with the abrasive grain enables operators to complete more parts per disc and require fewer disc changes. The exceptional life and cut of these 787C fibre discs make them one of 3M’s best grinding discs for high production environments, providing significant gains over conventional fibre discs. With jobs where a higher-tier fibre disc could be under-utilised but productivity is still your bottom line, these fibre discs deliver outstanding throughput. Step up production with 3M Precision Shaped Grain Developed for improved output on light to heavy stock removal, 3M Precision Shaped Grain lets operators finish tough tasks faster and with less fatigue. It wears evenly, and because the abrasive itself stays cooler and sharper, PSG abrasives last significantly longer than their conventional ceramic counterparts, ensuring extended high performance in production applications. To accomplish this level of performance, 3M engineers apply proprietary micro replication technology to create precise triangular structures of 3M™ Ceramic Abrasive Grain, and then electrostatically orient them on the backing to form sharp peaks. These ultra-sharp peaks slice cleanly through metal rather than gouging or ‘ploughing’ as conventional abrasives do, and continuously self-sharpen as the points break off. Tips for optimal use Fibre discs are heavy-duty abrasives that feature a tough, stiff backing made from vulcanised fibre that resist wear and can handle tough grinding applications. For optimal performance, the disc should be used with a back up pad of the appropriate density for the application—a lighter density back up pad for lighter weight grinding applications, and a harder density back up pad for more heavy weight grinding applications. Using the correct back up pad for the application ensures that the abrasive mineral will re-sharpen, maximising the life of the abrasive. 3M Engineered for peak productivity 3M Abrasives engineers know abrasive construction.
