Engineered for ultra-rapid cut on carbon steel, 3M™ Roloc™ Fibre Disc 782C features 3M Precision Shaped Grain. With its outstanding cut, durability, and ease of use, this disc offers a major step up in performance over conventional fiber discs. Advanced abrasive technology makes it 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 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.

The exceptional life and cut of our 782C Fibre Disc make it one of 3M's best grinding discs for high production environments, providing significant gains over conventional fiber discs. When our highest-tier fiber disc may be under-utilized but productivity is still your bottom line, our 782C Fibre Disc delivers outstanding throughput. This fiber disc is an excellent choice for many applications such as:

  • Edge chamfering
  • Beveling
  • 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 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.

3M™ Roloc™ Fibre Disc 782C
Quick change discs offer fast disc changes, a centered disc, and smooth running
Roloc™ System Enables Easy Tool Attachment
To suit many different project needs, we offer these discs in a range of sizes and a variety of attachment styles. The 3M™ Roloc™ Fibre Disc 782C is available in 2-4" diameters for use with the following Roloc attachment systems: TR and TSP. Please select discs with the attachment design made for your system. We also offer 3M™ Fibre Disc 782C in larger sizes with a center hole and with GL and TN attachments (sold separately).

Tips for Optimal Use
Fiber discs are heavy-duty abrasives that feature a tough, stiff backing made from vulcanized fibre that resist 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 heavyweight grinding applications. Using the correct pad for the application ensures that the abrasive mineral will re-sharpen, maximizing 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 we offer a complete line of high quality metalworking abrasive solutions to meet your tough jobs. Our 3M™ Roloc™ 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.
