Norton 66261138609 Quick-change Disc 1in 50 Grit Zirconia

Product Description

The NORTON 66261138609 is a TS (Type II) quick-change coated abrasive disc designed for aggressive stock removal on metal, weld seams, and fabricated surfaces. At 1 inch in diameter with a 50-grit coarse zirconia alumina abrasive grain, this disc delivers sharp, fast cutting action with durability suited to high-pressure grinding applications. The polyester Y-weight backing provides a rigid platform that resists flexing under load, maintaining consistent abrasive contact. Part of the Norton R860 series, it is engineered for use with Type S attaching systems, allowing tool-free disc changes during production work.

This disc is intended for use on die grinders and right-angle grinders equipped with TS Type II quick-change mandrels. It suits applications in metal fabrication, maintenance and repair, and weld grinding where a small-diameter disc is required to access tight areas or contoured surfaces. The coarse 50-grit cut rate makes it appropriate for initial material removal rather than finishing passes. Metalworking professionals, pipefitters, and maintenance machinists are the primary installers and users of this product. It is sold individually with a minimum order quantity of 100 units.
