The disc measures 3 inches in diameter and carries a 100-grit aluminum oxide abrasive surface on a rigid X-weight 2-ply cloth and polyester backing. Rated to 20,000 RPM, this disc is built for consistent cut rate and extended service life in deburring, cleaning, and detailing operations. It is part of the Merit R766 series and is sold individually with a minimum order quantity of 50 units.

This disc is suited for use on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The fine-to-medium 100-grit classification makes it a practical choice for surface preparation, light material removal, and finishing work in fabrication shops, maintenance environments, and field service applications. It is installed on handheld disc sanders where quick-change compatibility and consistent performance on hard and soft metals are required.
