Our 3Mâ„¢ Cubitronâ„¢ II Rolocâ„¢ Fibre Disc 987C uses precision-shaped grain technology (PSG) for heavy duty metalworking applications. 3M’s PSG is an exceptionally high-performing ceramic, resin-bonded to a stiff fiber backing.
Our 3Mâ„¢ Fibre 987C products incorporate a grinding aid to keep the workpiece cooler, protecting heat-sensitive alloys from heat damage and reducing re-work. These features offer increased productivity for heavy-duty grinding on all metals, including stainless steel.
Recommended Applications
- Heavy duty metalworking applications
- Flame-cut edge cleanup
- Grinding
- High pressure grinding
- Right angle grinding
- Edge chamfering
- Weld removal and finishing
- Edge beveling
- Gate removal

To create PSG, engineers start with 3Mâ„¢ Ceramic Abrasive Grain and use proprietary technology to form the grains into triangular structures and electrostatically orient them on the backing to form sharp peaks that maximize cutting potential. These peaks slice cleanly through metal, rather than gouging or plowing as traditional abrasive grains do; and continuously self-sharpen as the points break off. This generates a super-fast cut and lessens heat build-up due to friction, reducing heat-related stress cracks and discoloration. PSG also wears evenly, and because the abrasive stays cooler and sharper, Cubitron II products last significantly longer than their conventional ceramic counterparts, ensuring extended high performance in production applications. Our Cubitronâ„¢ II products achieve a fast cut rate and a long product life.
