Norton 66261121049 Quick-change Disc 80 Grit 2 in

Product Description

The NORTON 66261121049 is a 2-inch quick-change abrasive disc designed for use with Speed-Lok TR (Type III) attachment systems on handheld disc sanders. Built around a zirconia alumina abrasive grain on a heavy Y-weight polyester backing, this disc runs at up to 30000 RPM and delivers aggressive stock removal at 80 grit (medium-coarse). The rigid construction resists flex during grinding, and the self-lubricating treatment helps reduce heat buildup during extended use. It is part of the Norton R860 series and is sold individually with a minimum order quantity of 25 units.

This disc is suited for metalworking, fabrication, and woodworking applications where fast cutting and consistent finish are required. Rated material applications include 300 and 400 series stainless steel, aluminum, brass, bronze, hard and soft carbon steels, fiberglass and composites, and hard and soft woods. Typical uses include weld blending, deburring, and surface stock removal on fabrication benches and in field service environments. It is installed and used by metal fabricators, pipefitters, millwrights, and general maintenance technicians.
