Norton 69957370198 Fiber Disc 5 in 50 Grit Ceramic Alumina

Product Description

The NORTON 69957370198 is a 5-inch ceramic alumina fiber disc designed for aggressive material removal on metal and other hard surfaces. Part of the F970 BlazeX Series, it uses a resinoid bond and a coated abrasive construction to deliver consistent cut rates across its service life. At 50 grit, this disc falls in the coarse grade range, making it well suited for weld blending, surface conditioning, deburring, and stock removal tasks. The fiber backing provides the rigidity needed to support heavy grinding pressure. It mounts via a 7/8-inch arbor hole and is rated to a maximum of 10,000 RPM.

This disc is used in fabrication shops, maintenance facilities, and field metalworking applications where fast, controlled stock removal is required. It fits standard right-angle grinders equipped with a backup pad sized for 5-inch fiber discs. The orange disc color identifies the BlazeX F970 Series product line. Typical applications include carbon steel, stainless steel, and cast iron surface prep and weld seam blending. This SKU is sold individually and requires a minimum order of 25 units.

Installation Notes

Fiber discs of this type are installed by metalworkers and fabricators using a backup pad threaded onto the grinder spindle. Before mounting, confirm the grinder's no-load RPM does not exceed the disc's 10,000 RPM rating. Inspect the disc for cracks or damage before each use and never operate a damaged disc. Always wear appropriate PPE including face shield and gloves when grinding.
