3M™ Roloc™ Fibre Disc 782C 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.

For an ultra-rapid cut on carbon steel, use 3M™ Roloc™ Fibre Disc 782C. Featuring 3M Precision Shaped Grain these discs offer outstanding cut, durability, and ease of use. Our discs offer a major step up in performance over conventional fibre discs. Advanced abrasive technology make them an excellent choice for tough applications including weld removal, blending, and finish refinement. Premium performance tackles carbon steel applications Balance cost and output by selecting the abrasive with precisely the right amount of cut and life. 3M™ Roloc™ Fibre Disc 782C contains Precision Shaped Grain (PSG) to optimise the balance of speed and longevity for many of your carbon steel operations. Disc construction includes a stiff fibre backing and strong resin bond that provide durability and tear-resistance, which along with fast-cutting abrasive grain enables operators to complete more parts per disc, and requires fewer disc changes. The exceptional life and cut of 782C fibre disc make it 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. This fibre disc is an excellent choice for many applications, such as edge chamfering, bevelling, and weld removal. 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. Roloc™ System enables easy tool attachment The Fibre Disc 782C is available in 5.08 cm - 10.16 cm diameters for use with TR and TSP Roloc attachment systems. Please select discs with the attachment design made for your system. Tips for optimal use Fibre discs are heavy-duty abrasives that feature a tough, stiff backing made from vulcanised fibre which resists wear, and can handle tough grinding applications. For optimal performance, the disc should be used with a 3M Roloc Disc Pad of the appropriate density for the application - a softer disc pad for lighter weight grinding applications, and a harder density disc pad for more heavy weight grinding applications. Using the correct 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. For more than 100 years 3M has been a leading abrasive supplier for the metalworking and woodworking industries, and offer a complete line of high quality metalworking abrasive solutions to meet your tough jobs. Fibre disc 782C is designed to enable operators to take production to the next level by completing more work in less time. It is a prime example of how 3M science provides advanced solutions to help industrial businesses operate faster, better and more efficiently.
