Merit Abrasives 69957399758 Quick-change Disc 180 Grit

Product Description

The MERIT ABRASIVES 69957399758 is a 1-inch diameter quick-change coated abrasive disc designed for use with Power-Lock Type 1 attachment systems on handheld disc sanders. It uses aluminum oxide abrasive on a rigid X-weight 2-ply polyester backing, rated for a maximum of 40,000 RPM. At 180 grit, this disc falls in the very fine range, making it well-suited for precision deburring, surface cleaning, and detailing work on tight or hard-to-reach surfaces. The polyester backing adds durability and supports a faster cut rate compared to lighter backing materials.

This disc is intended for use on metal surfaces in both shop and field applications. It is designed for handheld disc sanders and applies to materials including 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. Its small 1-inch diameter makes it particularly useful for detailed work, tight contours, and areas where larger discs cannot reach. The Series R766 construction balances cut speed with disc longevity across these material types.
