Norton 66261132739 Quick-change Disc 3 in 80 Grit Ceramic

Product Description

The NORTON 66261132739 is a 3-inch quick-change abrasive disc in the Norton R983 series, designed for high-speed material removal on metal surfaces. It uses a ceramic alumina abrasive blend bonded to a polyester backing and attaches via the Type R (Speed-Lok TR) quick-change system. Rated at 20,000 RPM maximum, this disc is built for use with handheld disc sanders in demanding fabrication and finishing environments. The self-lubricating grain treatment extends disc life and helps maintain cut rate as the disc wears. At 80 grit, it falls in the medium-to-coarse range, suited for aggressive stock removal and surface prep.

This disc is intended for grinding and finishing work on 300 series stainless steel, 400 series stainless steel, cast iron, and soft carbon steels. Typical applications include weld blending, surface conditioning, and deburring in metal fabrication shops, maintenance facilities, and industrial worksites. It mounts to any handheld disc sander equipped with a Type R quick-change hub, allowing fast disc swaps without tools. The polyester backing provides flexibility and resistance to tearing during aggressive grinding passes.
