3M™ Fibre Disc 988C offers an exceptionally fast cut and extreme durability for high-pressure carbon and mild 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.

3M™ Fibre Disc 988C
3M's premium disc for long-lasting performance for mild steel grinding
Choose our 3M™ Fibre Disc 988C for high-pressure stock removal, weld leveling, and beveling. This disc is compatible with 3M™ disc pad face plates and hubs, and requires the use of a disc retainer nut (all sold separately). The disc is resin-bonded to withstand high heat and pressure in demanding applications.

Our 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 cut-rate, in turn reducing operator fatigue and extending tool life. 3M™ Ceramic Abrasive Grain is a 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. 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 inch 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 sanding applications, and a harder density face plate for coarse grade sanding applications. Using the correct face plate for the application ensures that the abrasive mineral will continually re-sharpen, maximizing the life of the abrasive.
