3M Fibre Disc Regalite 785C 114mm 120G

Our 3M™ Fibre Disc 785C incorporates a grinding aid to keep the workpiece cooler, protecting heat sensitive alloys from heat damage and reducing re work. These features along with a stiff fiber backing offer increased productivity for heavy duty grinding on all metals, including stainless steel. Fiber discs with a 7/8" center hole are mounted onto a right angle grinder. They are secured to the disc pad hub and face plate with a compatible disc retainer nut (all sold separately). 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 fracture as it should, maximizing the life of the abrasive. Our 3M™ ceramic abrasive grain is a ceramic mineral designed using a 3M process which enhances hardness and toughness of the grain. For increased performance, 3M™ Fibre Disc 785 products feature aluminum oxide blended with 3M™ Ceramic Abrasive Grain, yielding excellent performance on any metal. Perfect for moderate to heavy stock removal, ceramic abrasives are engineered to cut fast and handle intense heat and stress applications. Ceramic/aluminum oxide blends surpass regular aluminum oxide abrasives in cut rate and durability, making them an excellent choice for difficult grinding applications. Fiber discs are heavy duty discs ideal for weld removal, grinding, and blending large and small areas of metal surfaces. They feature a tough, stiff backing made from hardened fibers that resist wear and can handle tough grinding applications.

Ceramic aluminum oxide 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

7/8" center hole mount is 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
