Norton 69957399788 Quick-change Cloth Disc 3in P50 Coarse

Product Description

The NORTON 69957399788 is a quick-change cloth disc designed for aggressive material removal in grinding and blending applications. It uses aluminum oxide abrasive on a Y-weight polyester backing, delivering consistent cut and durability under sustained load. The disc measures 3 inches in diameter, carries a P50 coarse grit rating, and is rated for up to 20000 RPM. The TP (Type 1) quick-change attachment makes disc swaps fast and tool-free, reducing downtime on the job. These discs are brown in color and sold in boxes of 50, making them practical for high-volume shop and field use by metal fabricators, welders, and maintenance technicians.

This disc is suited for use on metal surfaces where rapid stock removal or weld blending is required. The coarse P50 grit makes it appropriate for rough grinding passes, deburring, and surface preparation before finishing steps. The Y-weight polyester backing resists tearing and flexing under load, making it reliable on both flat and moderately contoured surfaces. Typical applications include fabrication shops, maintenance facilities, and production grinding operations where a quick-change system is already in use.
