- Rapidly cuts hard to grind metals like stainless steel and high nickel alloys
- Premium mineral excels at heavyweight applications such as weld grinding, beveling, and edge chamfering
- 3M Precision Shaped Grain yields higher cut rates and cooler cut while completing more parts per disc than conventional fibre discs
- Grinding aid minimizes grinding temperatures for heat-sensitive alloys
- Long-lasting disc helps reduce cost
- Stiff fiber backing and strong resin bond provide durability and tear-resistance
- 3M™ Roloc™ attachment locks disc securely into place, no tools required
Engineered for ultra-rapid cut, 3M™ Roloc™ Fibre Disc 787C 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. Constructed with a grinding aid, it is an excellent choice for weld removal, blending, and finish refinement on stainless steel and high nickel alloys.
Step Up Production with 3M Precision Shaped Grain
- Edge chamfering
- Weld removal
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.
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 787C is available in 2-4" diameters for use with the following Roloc attachment systems: TSM and TR. Please select discs with the attachment design made for your system. We also offer 3M™ Fibre Disc 787C in larger sizes with a center hole or 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 applicationa 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.
