Norton 66261121019 Quick-change Disc 2 in 36 Grit

Product Description

The NORTON 66261121019 is a coated quick-change abrasive disc designed for aggressive material removal in grinding and surface preparation applications. Part of the Speed-Lok TR (Type R) system, this disc mounts and releases without tools, making it a practical choice for production grinding, weld blending, and rust removal. The 36-grit aluminum oxide abrasive delivers very coarse stock removal on ferrous and non-ferrous metals. Backed by an X-weight cloth backing, the disc resists tearing under load and maintains flexibility against irregular surfaces. Licensed electricians, metal fabricators, maintenance technicians, and HVAC sheet metal workers commonly use discs of this type during installation and repair work.

This disc is suited for use on portable right-angle grinders and die grinders equipped with a Type R Speed-Lok quick-change hub. The 2-inch diameter makes it appropriate for tight clearances, inside corners, and detail work where larger discs cannot reach. Brown aluminum oxide grain and X-weight cloth backing are standard in heavy-duty surface conditioning on steel, stainless, aluminum, and similar substrates. It is sold individually with a minimum order quantity of 25 units.
