Norton 66261121036 Quick-change Disc 120 Grit 3 in

Product Description

The NORTON 66261121036 is a 3-inch coated abrasive quick-change disc from the Gemini R228 series, designed for use with Speed-Lok TR (Type III) and Type R attaching systems. It features 120-grit aluminum oxide abrasive on an X-weight, 2-ply cloth backing, rated to 20,000 RPM. The disc delivers consistent material removal for deburring, cleaning, and detailing operations on stainless steel, aluminum, and a range of ferrous and non-ferrous metals. It is installed and used by metalworkers, fabricators, and maintenance technicians using handheld disc sanders.

This disc is suited for both light industrial and general fabrication environments where controlled surface finishing is required. Typical applications include deburring cut edges, cleaning weld areas, and surface preparation on 300 and 400 series stainless steel, aluminum, brass, bronze, soft and hard carbon steels, and titanium. The flexible cloth backing conforms slightly to irregular surfaces, making it useful for contour work and detail passes where a rigid disc would leave uneven results.
