Norton 66261138175 Quick-change Disc 3 in 120 Grit

Product Description

The NORTON 66261138175 is a 3-inch coated abrasive quick-change disc from the Gemini R228 series, designed for use with TS (Type II) / Type S attaching systems on handheld disc sanders. It features a 120-grit aluminum oxide abrasive bonded to an X-weight, 2-ply cloth backing that delivers durability and flexibility during deburring, surface cleaning, and detail work. The disc is rated to 20000 RPM and is suited to fine finishing passes on metal surfaces where consistent cut and backing integrity are required. Licensed trade metalworkers and fabrication professionals are the primary installers and users of this consumable.

This disc is designed for use on a range of metals including 300 and 400 series stainless steel, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It is particularly well matched to deburring, cleaning, and detailing operations on stainless steel and soft metals. The flexible cloth backing allows the disc to conform slightly to irregular surface profiles, making it useful in both flat and contoured finishing applications with a handheld disc sander.
