Norton 66261043386 Quick-change Disc 120 Grit 2 in

Product Description

The NORTON 66261043386 is a 2-inch quick-change coated abrasive disc designed for aggressive material removal and finishing work on metal surfaces. Part of the R980P series, it features 100% ceramic alumina grain that continuously fractures to expose sharp cutting edges, paired with a resin bond system engineered to maximize grain retention throughout the disc life. The polyester Y-weight backing provides rigidity and durability under load. A self-lubricating grain treatment reduces heat buildup at the workpiece, supporting faster cut rates with less risk of heat discoloration. This disc mounts via a Speed-Lok TR (Type III) attachment system and is rated for handheld disc sander use.

This disc is suited for stock removal, weld blending, and deburring on 300 series and 400 series stainless steel in fabrication, maintenance, and field repair applications. The 120-grit fine grade makes it appropriate for finishing passes following heavy stock removal, or as the primary abrasive where a refined surface finish is required without secondary blending. It is sold individually and ordered in multiples of 25, making it practical for stocking in shop or service van environments where consistent abrasive supply is needed.

Installation Notes

Install and change discs only with the tool powered off and disconnected from its power source or air supply. Verify the tool spindle accepts the Speed-Lok TR (Type III) attachment before mounting. Do not exceed the maximum rated RPM for the disc. Inspect the disc for cracks or damage before each use and discard any disc showing signs of wear through the backing or delamination.
