Norton 66261138140 Quick-change Disc 120 Grit 2 Inches

Product Description

The NORTON 66261138140 is a 2-inch diameter, 120-grit aluminum oxide quick-change abrasive disc designed for use with TS (Type II) Type S attaching systems on handheld disc sanders. Part of the Gemini R228 series, it features a flexible, X-weight 2-ply cotton cloth backing that supports consistent stock removal across a range of metal surfaces. The coated aluminum oxide abrasive delivers fine-grade cutting action suited for deburring, cleaning, and detailing work. Rated to 30000 RPM, this disc handles the demands of professional metalworking without backing breakdown under load. Licensed trades and fabrication shops rely on this format for repeatable results on production and finishing tasks.

This disc is built for metalworking applications across a broad range of materials including 300 and 400 series stainless steel, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It is well suited for deburring, surface cleaning, and detail finishing in both shop and field environments. The TS (Type II) quick-change mount allows fast disc swaps on compatible handheld disc sanders, reducing downtime during multi-step finishing operations. Typical users include metal fabricators, pipefitters, welders, and industrial maintenance technicians.
