Details

  • 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
  • Compatible with 3M™ disc pad face plates and hubs (sold separately)

Engineered for ultra-rapid cut, 3M™ Fibre Disc 787C features 3M Precision Shaped Grain. With its outstanding cut, durability, and ease of use, this disc offers a 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.

3M™ Fibre Disc 787C
The sharpness of 3M precision-shaped grain delivers a high initial cut

The Advanced Solution for Challenging Applications 
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 787C (PDF, 395 Kb) contains the exact amount of precision shaped grain (PSG) you need to optimize the balance of speed and longevity for challenging applications from grinding to deburring. Moreover, to keep the disc and workpiece cool, a grinding aid is incorporated, further prolonging disc life. Disc construction includes a stiff fiber backing and strong resin bond that provide durability and tear-resistance, which along with abrasive grain enables operators to complete more parts per disc and requires fewer disc changes. 

The exceptional life and cut of our 787C 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 787C Fibre Disc delivers outstanding throughput. This fiber disc is an excellent choice for a range of applications such as:

  • Edge chamfering
  • Beveling
  • Deburring
  • 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.

Quick Change Attachments

Choice of Power Tool Attachment 
To suit many different project needs, we offer these discs in a range of sizes and a variety of attachment styles. Larger sized discs have a 7/8 inch center hole and require the use of a 3M™ disc pad face plate and hub, which are attached to a right angle grinder (PDF, 5.1 Mb) with a disc retainer nut (all sold separately). GL and TN quick change attachments are an option for 4-1/2 inch to 7 inch discs. Smaller sized quick change Roloc™ Discs are also available (sold separately) and provide reliable attachment to the tool and easy disc changes between applications. 

Tips for Optimal Use 
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. 

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™ Fibre Disc 787C 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.
