Merit Abrasives 69957399604 Quick-change Disc 50 Grit

Product Description

The MERIT ABRASIVES 69957399604 is a coated quick-change abrasive disc designed for use with Power-Lock Type S attachment systems on handheld disc sanders. The disc measures 3/4 inches in diameter and carries a 50-grit aluminum oxide abrasive in a coarse grade. It features a Y-weight 2-ply polyester cloth backing that adds rigidity and prolongs disc life while maintaining a fast cut rate. Rated to 40,000 RPM, this disc is suited for high-speed grinding and finishing tasks performed by metal fabricators, maintenance technicians, and trade professionals working on ferrous and non-ferrous metals.

This disc is intended for deburring, cleaning, and detailing operations on a range of metal substrates including 300 Series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It is compatible with handheld disc sanders that accept a Type S Power-Lock quick-change attachment. The small 3/4-inch diameter makes it well suited for detail work, tight contours, and confined areas where larger discs cannot reach effectively. It is sold individually with a minimum order quantity of 100 units.
