3M™ Cubitron™ II Fibre Disc 987C, 4-1/2 in x 7/8 in 80+, 25 per inner 100 per case


3M™ Cubitron™  II Fibre Disc 987C offers significant gains in productivity on medium to heavy-duty operations with our exceptionally high-performing 3M Precision Shaped Grain combined with a stiff fiber backing. This disc achieves a higher cut-rate, greater durability, and longer life than other fiber discs—all with less grinding pressure.

UPC: 51141276571 Categories: , , ,


Designed for stainless steel and other heat-sensitive applications, the 3M precision-shaped grain improves disc life (up to 2 times or more), cuts faster and can increase productivity compared to other leading ceramic discs. Takes time out of edge chamfering, beveling and removing stainless steel welds, mill scale, pits and imperfections, machining grooves and more to deliver a lower cost per grind.

  • PSG runs cooler and disc life is significantly longer, completing more parts per disc and requiring fewer disc changes
  • Stiff fiber backing and a strong resin bond provide durability and tear-resistance for heavyweight applications such as high-pressure weld grinding or beveling
  • Grinding aid incorporated on the disc minimizes grinding temperatures for heat-sensitive alloys
