Features and benefits

This disc features a high-quality aluminum oxide grain, providing up to 20% higher cut rate and 50% better performance than competitive products.

The premium high-loft nylon fiber is bonded to a strong nylon scrim backing, allowing for a thick layer of resin bond and grain for extended life, added durability, and stiffness.

Proprietary Clean Bond resin technology guarantees smear-free finishes even on high nickel content alloys and reduces loading on aluminum and other soft metals.

Waterproof and washable
