Item Details

  • Engineered for ultra-rapid cut, 3M™ Fiber 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.

  • 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 fiber 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)
