Norton 63642595470 Quick-change Disc 2 in 36 Grit

Product Description

The NORTON 63642595470 is a 2-inch coated abrasive quick-change disc engineered for aggressive material removal on metal surfaces. Built on a polyester Y-weight backing, it uses 100% ceramic alumina grain at 36 grit (extra coarse) to deliver fast stock removal, weld blending, and deburring. The resin bond system maximizes grain retention across the disc life, while a self-lubricating grain treatment reduces heat buildup during extended grinding passes. Rated to 30,000 RPM, it is designed for use with handheld disc sanders equipped with a Speed-Lok TR (Type III) quick-change interface. The orange disc with black button is part of the R980P series.

This disc is suited for fabrication shops, weld finishing operations, and metal surface prep tasks on 300 and 400 series stainless steel. The quick-change TR attachment system allows rapid disc swaps without tools, reducing downtime during high-volume grinding work. It is well matched to professional metalworkers, pipefitters, and fabricators using handheld disc sanders in both shop and field environments. Sold individually, with a minimum order quantity of 25 units per order.

Installation Notes

Installation is performed by metalworkers and fabricators using compatible handheld disc sanders. Before mounting, confirm the tool spindle uses a TR (Type III) quick-change interface and that the tool is rated for the disc RPM. Always power down and disconnect the sander before changing discs. Inspect the disc for cracks or damage before each use and never exceed the maximum rated RPM marked on the disc.
