Merit Abrasives 69957399710 Quick-change Disc 80 Grit 2 in

Product Description

The MERIT ABRASIVES 69957399710 is a 2-inch coated abrasive quick-change disc engineered for use with TR (Type III) and Type R quick-change attachment systems on handheld disc sanders. The disc features aluminum oxide grain bonded to a rigid, X-weight, 2-ply cloth and polyester backing, delivering consistent stock removal at 80 grit (medium grade). Rated to 30,000 RPM, the R766 series disc is built for deburring, cleaning, and detailing work on stainless steel, soft metals, and hard alloys. Licensed metal fabricators, weld finishers, and maintenance technicians are the primary installers and operators.

This disc is suited for both light fabrication shops and production-floor finishing applications. Its rigid backing maintains consistent contact geometry on flat and near-flat workpiece surfaces. Approved material applications include 300 series stainless, 400 series stainless, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It mounts directly to handheld disc sanders equipped with TR or Type R quick-change arbors, making it practical for rapid disc changes during multi-step finishing sequences.

Installation Notes

This disc is installed and operated by metal fabricators, weld finishers, and general maintenance technicians.
