Merit Abrasives 69957399698 Quick-change Disc 80 Grit

Product Description

The MERIT ABRASIVES 69957399698 is a coated quick-change abrasive disc designed for use with Power-Lock Type 3 (TR/Type III) attachment systems. It measures 1.5 inches in diameter, carries an 80-grit aluminum oxide abrasive on a rigid, X-weight 2-ply cloth and polyester backing, and is rated for up to 30,000 RPM. The aluminum oxide grain delivers consistent cut on a broad range of metals. Medium-grade grit makes this disc well suited for deburring, surface cleaning, and detailing work where controlled material removal is needed without aggressive stock loss.

This disc is intended for handheld disc sanders used in metal fabrication, maintenance, and finishing operations. Its material compatibility list covers 300 and 400 series stainless steel, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The rigid cloth backing maintains disc geometry under lateral pressure, making it practical for tight-radius edges and weld seam cleanup. It is sold individually but carries a minimum order quantity of 100 units, making it appropriate for shop stocking.
