3M Cubitron II Fibre Disc 982C uses 3M Precision-Shaped Grain to generate up to twice the cut-rate, durability, and life of other fiber discs when grinding carbon steel all with less grinding pressure required by the operator. That means less operator fatigue, faster throughput, and more parts per disc when tackling medium and high-pressure grinding applications.

  • CUTS FAST — 3M Precision-Shaped Grain cuts exceptionally fast with less pressure to boost productivity
  • LASTS LONG — Maintains sharp cutting edges throughout the life of the disc, reducing changeouts
  • DURABLE RESIN BOND — Resin bond and stiff fiber backing improve durability and tear resistance in high-pressure grinding
  • ROBOT READY — Cutting speed and durability reduce changeouts and downtime in robotic and pressure-assisted applications
  • OPTIMIZED FOR CARBON STEEL — Quickly bevels and grinds welds on carbon steel and mild steel
  • WORKS WITH THE TOOLS YOU HAVE – Designed for use with pneumatic or electric angle grinder

  1. What is the 3M™ Cubitron™ II Fibre Disc 982C made of?

    The 3M™ Cubitron™ II Fibre Disc 982C consists of a ceramic aluminum oxide abrasive blend that provides high stock removal rates and long disc life.

  2. What is the grit size of this disc?

    This particular version has a grit size of 36+, which means it's considered "coarse" and suitable for heavy grinding applications.

  3. How big is each disc in this case, and how many are included?

    Each disc measures 5 inches (127 mm) in diameter with a standard attachment design called "7/8 inch center hole." This case includes four inner boxes, each containing twenty-five discs for a total of one hundred.

  4. . Is this fibre disc compatible with my grinder?

    Yes! The die number on these discs corresponds to their compatibility with specific tools - our website offers detailed reference guides to help you confirm compatibility.

  5. . Can I buy fewer than one hundred discs at once?

    A. Of course you can! While cases often offer economies of scale best suited for medium-to-large volume users, we offer alternative packaging options like smaller sleeves to accommodate your individual needs as well!

Boost Productivity with 3M Cubitron II Fibre Disc 982C

Improve the efficiency of your shop with the 3M Cubitron II Fibre Disc 982C. This ceramic grinding disc uses 36+ grit 3M Precision-Shaped Grain to generate up to twice the cut-rate of other fibre discs. The ceramic grain lasts exceptionally long, continuously fracturing into super-sharp points and edges that slice cleanly through metal. By grinding faster than other discs, this 3M fibre disc allows you to complete more parts and boost productivity.

Durable and Versatile

The 3M Cubitron II Fibre Disc 982C features a stiff fiber backing and strong resin bond, making it durable enough for heavyweight applications like high-pressure weld grinding and beveling. With durability comes longer abrasive life, reducing the amount of time spent changing out abrasives and further boosting productivity. This 5 inch grinding disc can be used with either pneumatic or electric tools.

Reduced Grinding Pressure

The 3M Cubitron II Fibre Disc 982C helps reduce downtime in the cell by lasting exceptionally long and maintaining a high cut-rate through the entire life of the disc. In robotic or pressure-assisted operations, this disc reduces the amount of grinding pressure exerted by the operator, further increasing productivity.

Optimized for Carbon Steel

The 3M 982C fibre disc is optimized for use on carbon steel. For stainless steel, consider using 3M™ Cubitron II Fibre Disc 987C.
