Norton 63642595493 Quick-change Disc 3in 80 Grit Ceramic Alumina

Product Description

The NORTON 63642595493 is a 3-inch coated abrasive quick-change disc designed for aggressive stock removal, weld blending, and deburring on metal surfaces. It uses 100% ceramic alumina grain, which continuously fractures during use to expose sharper cutting edges, maintaining cut rate throughout the disc life. The resin bond system holds grain firmly in place, extending disc life under heavy use. A self-lubricating grain treatment reduces heat buildup, protecting both the workpiece and the disc. This disc is built for trade professionals who need fast, consistent material removal with minimal downtime between disc changes.

This disc is suited for handheld disc sander applications in fabrication, maintenance, and finishing environments. It is rated for use on 300 series and 400 series stainless steel, making it a practical choice for shops and field techs working with stainless fabrication or weld cleanup. The Speed-Lok TR Type R attachment system allows fast disc swaps without tools, reducing changeover time during production or service work. The polyester backing provides flexibility and durability under load. This disc sells in multiples of 25 and packages as a single disc unit.
