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.

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.

3M Roloc Fibre Disc

The 3M Roloc Fibre Disc 782C is designed for high performance with its 80+ grade, ensuring a balance of cut rate and disc life. This model features the trusted 3M Roloc attachment system, which locks the disc securely without tools, making it easy to change discs quickly.

Ideal for industrial use, this disc combines 3M’s Precision Shaped Grain technology with a durable fiber backing. The 4 inch size fits many common grinders, making it versatile for various metalworking tasks.

High Grade Abrasive Performance

With an 80+ grade, the 3M Roloc Fibre Disc 782C offers rapid cutting on carbon steel and excels in heavy-duty applications like weld grinding and beveling. The premium mineral abrasive ensures consistent performance and long-lasting use.

This disc’s stiff fiber backing and strong resin bond provide durability and tear resistance, allowing operators to complete more parts per disc and reduce downtime caused by disc changes.

Durable Backing And Size

The 4 inch diameter of the 3M Roloc Fibre Disc 782C is a common size that fits many Roloc attachment systems, including TR and TSP. This size offers a good balance between control and coverage for grinding tasks.

The fiber backing is vulcanized for toughness, resisting wear during heavy grinding. This makes the disc suitable for edge chamfering, beveling, and weld removal, supporting a wide range of metalworking needs.

Pack Count And Format

This product comes in a pack of 25 discs per carton and 100 discs per case, making it convenient for high-volume operations. The packaging supports efficient inventory management and ensures you have enough discs on hand for continuous work.

The die RS400BB format refers to the disc’s backing type, which is optimized for strength and compatibility with the 3M Roloc system. This format helps maintain disc stability during use.

Precision Shaped Grain Technology

3M’s Precision Shaped Grain (PSG) technology in the 782C disc creates sharp abrasive peaks that cut cleanly and stay cooler. This results in faster stock removal with less operator fatigue compared to conventional ceramic abrasives.

The PSG abrasive wears evenly and self-sharpens as points break off, extending disc life and maintaining high performance throughout its use. This makes the 3M Roloc Fibre Disc 782C a reliable choice for demanding grinding tasks.
