3M 5111160323 Close Coated Fiber Disc

3M fiber disc 983C offers an fast cut and extreme durability for high pressure carbon steel applications by combining 3M ceramic abrasive grain with 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. Choose 3M fiber disc 983C for high pressure weld leveling and beveling.

The disc is resin-bonded to withstand high heat and pressure in demanding applications. 3M ceramic 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 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 vulcanized fiber backing that resists wear and can handle tough grinding applications.

Fiber discs with a 7/8 in 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, experts recommend that the disc be used with a face plate of the appropriate density for the application - a lighter density face plate for fine grade applications and a harder density face plate for more coarse grade grinding applications. Using the correct face plate for the application ensures that the abrasive mineral will re-sharpen, maximizing the life of the abrasive.
