3M™ Cubitron™ II Fibre Disc 987C – 125mm × 22mm | 36+ Grit | Precision Shaped Ceramic | Pack of 25

Achieve faster grinding, longer disc life and greater productivity with the 3M™ Cubitron™ II Fibre Disc 987C, a premium 125mm × 22mm fibre abrasive disc engineered for heavy-duty metalworking applications. Featuring 3M Precision-Shaped Ceramic Grain, this professional-grade fibre disc cuts significantly faster while requiring less grinding pressure than conventional ceramic abrasives. Supplied in a pack of 25, the 987C 36+ is ideal for weld removal, beveling, heavy stock removal, edge chamfering and surface preparation on carbon steel, stainless steel and other heat-sensitive alloys.

The Precision-Shaped Grain (PSG) continuously fractures into sharp cutting points, maintaining an aggressive cutting action throughout the life of the disc. A built-in grinding aid helps reduce heat generation during grinding, minimising metal discolouration and the risk of heat-related damage on stainless steel and other sensitive materials. The stiff fibre backing and durable resin bond provide exceptional tear resistance and long service life, even under high-pressure grinding applications.

Designed for use with 125mm angle grinders and compatible ribbed backup pads, the Cubitron™ II 987C delivers outstanding performance across fabrication, welding, manufacturing, mining, shipbuilding and heavy industrial maintenance. By cutting faster, running cooler and lasting significantly longer than conventional fibre discs, it helps reduce downtime, increase productivity and lower the overall cost per grind.
