Product Benefits

  • 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)

More Product Details

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 a highest-tier fiber disc may be under-utilized but productivity is still your bottom line, the 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.

3M™ Fibre  Disc 787C 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.
Quick Change Attachments
Choice of Power Tool Attachment
To suit many different project needs, 787C discs are offered 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 se
