Core Performance

Engineered with 3M’s proprietary Cubitron 2 ceramic grains that self-sharpen during use, this disc delivers 30% faster cutting than conventional abrasives while reducing heat buildup. The quick-change Roloc system minimizes downtime between disc changes, increasing productivity by up to 25% in high-volume applications.

Quality Assurance

Backed by 3M’s 100+ years of abrasive expertise, each disc undergoes rigorous testing for consistency and performance. Manufactured to ISO 9001 standards, this product meets the highest industry requirements for safety and durability.

Differentiation

Unlike standard fibre discs, the Cubitron 2 technology features precision-shaped grains that maintain sharp cutting edges longer, reducing disc consumption by up to 40%. The versatile backing pad compatibility allows switching between aggressive stock removal (hard pads) and fine finishing (soft pads) without tool changes.
