13187M - 3M Cubitron II 982C Fibre Disc 9-1/8 Inch 36+ Grit

Industrial Performance with 3M Cubitron II Technology

The 3M™ Cubitron™ II Fibre Disc 982C (SKU: 13187) represents the pinnacle of abrasive technology for heavy industrial applications. Designed for 9-inch angle grinders, this 9-1/8" disc utilizes 3M's proprietary Precision Shaped Grain (PSG) technology to deliver a cut rate that far surpasses conventional ceramic and aluminum oxide discs. The 36+ grit formulation is specifically engineered for aggressive stock removal on carbon steel, making it an essential consumable for structural steel fabrication, heavy equipment manufacturing, and shipyards.

Unlike traditional abrasives that gouge or plow through the metal, the triangular-shaped ceramic grains in the 982C are electrostatically oriented to form sharp peaks. These peaks slice cleanly through metal like a knife, self-sharpening as they fracture. This mechanism prevents heat buildup, reducing the risk of heat-related stress cracks and discoloration on the workpiece. For industrial operators, this translates to significantly higher throughput and reduced downtime associated with disc changeovers.

Optimized for Carbon Steel

The 982C series is tailored for mild steel applications. The stiff fiber backing provides the necessary support for high-pressure grinding, ensuring the disc maintains its integrity even under the torque of a large 9-inch grinder. Whether you are removing heavy welds, beveling edges for preparation, or performing large-scale surface blending, the 13187 disc offers consistent performance from the first spark to the last.

Cost-Efficiency and Safety

While premium abrasives carry a higher initial unit cost, the total cost of grinding is reduced through labor savings and extended product life. Operators experience less fatigue as the PSG technology requires less downward pressure to achieve the desired cut. This ergonomic benefit, combined with the sheer speed of removal, makes the 3M Cubitron II 982C a smart investment for any high-volume production environment.
