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.

  • 3M Precision-Shaped Grain maintains super-sharp points that cut exceptionally fast with less pressure
  • Disc life is significantly longer, completing more parts per disc and requiring fewer disc changes
  • Reduces changeouts and downtime in manual, robotic and pressure-assisted applications
  • Triangular shaped ceramic grain lasts up to two times longer than other ceramic abrasives—it wears evenly, runs cool, and optimizes mineral breakdown
  • Stiff fiber backing and a strong resin bond provide durability and tear-resistance for heavyweight applications such as high-pressure weld grinding and beveling

Raising the Bar in Abrasives

This premium fibre disc sets a new standard in speed and stock removal. 3M engineers have developed a revolutionary process using Precision-Shaped Grain technology. The triangular shaped ceramic grains are electrostatically oriented on the backing, forming sharp peaks that maximize cutting potential. These peaks act as individual cutting tools, slicing through metal and continuously fracturing into new sharp cutting edges. The grains wear evenly and self-sharpen, reducing heat due to friction and delivering up to twice the life of other fibre discs. With less grinding pressure required, the 3M Cubitron II Fibre Disc 982C outperforms and outlasts every conventional ceramic industrial abrasive disc on the market. This results in increased productivity and reduced overall abrasive spend.

Ideal for Robotic Weld Grinding

In medium and high-pressure applications such as robotic weld grinding, it is crucial to choose a high-performance abrasive that cuts fast and lasts long. The self-fracturing mineral in the 3M Cubitron II Fibre Disc 982C ensures that your robot can continue grinding welds long after other abrasives have worn out. This reduces downtime and maximizes efficiency, allowing your operations to run smoothly.

If you are curious about robotic material removal, our dedicated team of 3M robotics application engineers is ready to partner with you on your automation journey. From the initial idea to implementation, we are here to provide expertise and support.
