3M™ 5111155975 Close Coated Fiber Disc, 7 in Dia Disc, 7/8 in Center Hole, 80 Grit, Medium Grade, Ceramic Abrasive, Arbor Attachment

3M™ fiber disc 985C offers an exceptionally fast cut and extreme durability for high pressure applications on all metals by incorporating 3M™ ceramic abrasive grain and a grinding aid on a stiff fiber backing. Designed for both long life and superior performance in aggressive, heavy duty applications, ceramic fiber discs minimize edge wear, enhance productivity and reduce material consumption.Oufibre disc 985C incorporates a grinding aid to keep the workpiece cooler, protecting heat sensitive alloys from heat damage and reducing re-work. Choose this disc for high pressure stock removal, weld leveling and beveling on all metals, especially stainless steel. The disc is resin-bonded to withstand high heat and pressure in demanding applications. 3M™ ceramic abrasive grain exceeds conventional abrasives in durability, disc life and cut rate offering greater throughput in less time. Additionally, less pressure is required to achieve maximum performance, in turn reducing operator fatigue and extending tool life. 3M™ ceramic abrasive grain is a 3M™ proprietary ceramic mineral formed using a process to enhance toughness and hardness of the grain. It is chemically engineered with a unique "stay sharp" crystalline structure, which continually self-sharpens cutting edges on the surface of the disc, ensuring extended high performance in high pressure production environments, even on the toughest materials. These discs enable operators to do more work in less time, for significant gains in productivity. 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 vulcanized fiber that resist wear and can handle tough grinding applications. Fiber discs with a 7/8 in center hole are mounted onto a right angle sander. 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 fine grade grinding applications and a harder density face plate for coarse grade grinding applications. Using the correct face plate for the application ensures that the abrasive mineral will continually re-sharpen, maximizing the life of the abrasive.
