3M(TM) Fibre Disc 785C GL Quick Change
3M™ Fibre Disc 785C is a durable fiber disc featuring high-performance 3M ceramic/aluminum oxide blend abrasive ideal for blending, grinding applications, and weld removal. Our proprietary ceramic/aluminum oxide blend stands up to challenging applications, outcutting and outlasting aluminum oxide.


  • Ceramic/aluminum oxide abrasive blend self-sharpens yielding high cut rates and increased durability
  • Stiff fiber backing provides the durability needed for weld removal and other medium pressure applications such as deburring or rust removal
  • Grinding aid reduces grinding temperatures for processes involving heat-sensitive alloys such as stainless steel, nickel alloys, and titanium
  • Compatible with 3M™ disc pad face plates and hubs, and requires the use of a disc retainer nut (all sold separately)
  • Available in a variety of sizes to suit different applications
