Norton 66261138671 Quick-change Disc 2 in 36 Grit Zirconia

Product Description

The NORTON 66261138671 is a 2-inch quick-change abrasive disc designed for fast stock removal and surface conditioning in demanding trade applications. Built on a heavy Y-weight polyester backing, it runs at up to 30,000 RPM on handheld disc sanders. The zirconia alumina abrasive grain is rated 36 grit, placing it in the very coarse range, which makes it well-suited for aggressive grinding, weld blending, and deburring. A self-lubricating treatment helps manage heat buildup during extended use. The Speed-Lok TR (Type III) attachment system provides secure, tool-free disc changes, reducing downtime on the job. Fabricators, welders, and metalworkers are the primary users of this disc.

This disc is rated for use on a broad range of materials including 300 and 400 series stainless steel, aluminum, brass, bronze, fiberglass and composites, hard and soft carbon steels, and hard and soft woods. It is designed for use with handheld disc sanders equipped with a Speed-Lok TR or Type R attachment system. The rigid backing keeps the disc flat against the workpiece, which is critical for consistent weld blending and flat surface stock removal. It is sold individually with a minimum order quantity of 25 units per purchase.
