Norton 66261138165 Quick-change Disc 2in 40 Grit Aluminum Oxide

Product Description

The NORTON 66261138165 is a coated abrasive quick-change disc designed for use with Speed-Lok TS (Type II) attachment systems on handheld disc sanders. Part of the Gemini R766/R228 series, this 2-inch diameter disc uses aluminum oxide abrasive grain on a cloth and polyester backing with an X/Y-weight, 2-ply construction. At 40 grit, it falls in the extra coarse grade range, making it well suited for aggressive material removal, deburring, and surface cleaning on metals. The disc is rated to 30,000 RPM and features a brown face with a silver Type S button for quick mounting and release without tools.

This disc is intended for use on ferrous and non-ferrous metals in fabrication, maintenance, and finishing applications. Rated material compatibility includes 300 and 400 series stainless steel, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It is commonly used by fabricators, maintenance technicians, and metalworkers for deburring, cleaning, and detailing work on stainless steel and soft metals. The flexible backing allows the disc to conform slightly to irregular surfaces during handheld sanding operations.
