Balance cost and output by selecting the abrasive with precisely the right amount of cut and life, no more and no less. 3M™ Fibre Disc 782C contains Precision Shaped Grain (PSG) to optimize the balance of speed and longevity for many of your carbon steel operations. Disc construction includes a stiff fiber 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.

Developed for improved output on light to heavy stock removal, 3M Precision Shaped Grain lets operators finish tough tasks faster and with less fatigue. Because the grain wears evenly and stays sharp, 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 microreplication 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 “plowing” as conventional abrasives do, and continuously self-sharpen as the points break off.

Fiber discs are heavy-duty abrasives that feature a tough, stiff backing made from vulcanized fiber that resist wear and can handle tough grinding applications. For optimal performance, the disc should be used with a face plate of the appropriate density for the application—a lighter density face plate for lighter weight grinding applications, and a harder density face plate for more heavyweight grinding applications. Using the correct face plate for the application ensures that the abrasive mineral will re-sharpen, maximizing the life of the abrasive.
