Norton 69957370210 Fiber Disc 50 Grit 5 Inches Ceramic Alumina

Product Description

The NORTON 69957370210 is a 5-inch ceramic alumina fiber disc designed for aggressive material removal on metal, stainless steel, and hard alloys. Part of the BlazeX F970 Series, it uses a resinoid bond and a fiber backing to deliver a coarse 50-grit cut that holds up under sustained pressure. The threaded arbor hole accepts a 5/8-11 spindle, so it mounts directly to compatible angle grinders and disc sanders using the Norton Speed-Change Back-Up Pad. At 10,000 RPM max, this disc suits high-demand grinding and blending tasks in fabrication and maintenance environments.

This disc is suited for use in metal fabrication shops, structural steel work, weld prep, and surface conditioning applications. The coarse 50-grit ceramic alumina abrasive cuts aggressively on ferrous and non-ferrous metals. It is typically installed by welders, ironworkers, pipefitters, and metal fabricators who require consistent stock removal across repeated passes. The disc ships individually but carries a minimum order quantity of 25 units, making it practical for shop stocking.

Installation Notes

Installation is performed by the operator or trade professional using the appropriate Norton Speed-Change Back-Up Pad. Before mounting, ensure the grinder is unplugged or the power source is fully isolated. Verify that the tool's rated RPM meets or exceeds the disc's 10,000 RPM maximum before operation. Inspect the disc for damage before each use and never exceed the marked maximum speed.
