Norton 66261138075 Quick-change Disc 120 Grit 1 Inch

Product Description

The NORTON 66261138075 is a quick-change coated abrasive disc from the Gemini R228 series, designed for use with Type S (TS Type II) attaching systems on handheld disc sanders. The disc measures 1 inch in diameter and uses an aluminum oxide abrasive at 120 grit for fine-grade material removal. A 2-ply X-weight cotton cloth backing delivers the rigidity and durability needed for consistent deburring, cleaning, and surface detailing work on stainless steel, soft metals, and carbon steels. Rated to 40,000 RPM, this disc handles demanding production and finishing tasks in metal fabrication and maintenance environments.

This disc is suited for both production shop and field maintenance applications involving metal surface prep and detailing. It performs on 300 and 400 series stainless steel, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The flexible cloth backing conforms to contoured surfaces, making it practical for tight-access deburring and light blending work. It is installed on handheld disc sanders equipped with a Speed-Lok TS quick-change system, keeping tool changeover fast during multi-step finishing sequences.
