The 3M™ Cubitron™ II Roloc™ Fibre Disc 987C is designed for heavy duty metalworking applications such as weld grinding, beveling and flame-cut edge clean-up. This product uses 3M Precision Shaped Ceramic Grain on a fibre backing for fast grinding and blending. Our 3M™ Cubitron™ II Roloc™ Fibre Disc 987C uses 3M Precision Shaped Ceramic Grain (PSG) on a fibre backing for fast grinding and blending. Our 3M™ Cubitron™ II Roloc™ Fibre Disc 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. To create PSG, 3M engineers start with 3M 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 and continuously self-sharpen as the points break off, rather than gouging or 'plowing' as traditional abrasive grains do. This generates a super-fast cut and lessens heat build-up due to friction, reducing heat-related stress cracks and discolouration. PSG also wears evenly and because the abrasive stays cooler and sharper, 3M™ Cubitron™ Products last significantly longer than their conventional ceramic counterparts, ensuring extended high performance in production applications. Our 3M™ Cubitron™ Products achieve a fast cut rate and a long product life.
