Norton 662611-38590 Fiber Disc 7in 80 Grit Norzon F826 25pk

Product Description

The NORTON 662611-38590 is a 7-inch zirconia alumina fiber disc designed for aggressive material removal on metal, weld seams, and fabricated steel components. Built on the NorZon F826 abrasive platform, this disc combines a tough fiber backing with self-sharpening zirconia alumina grain that fractures during use to expose fresh cutting edges. The 80-grit designation places it in the coarse range, making it a strong choice for weld blending, rust removal, and surface conditioning tasks where stock removal rate matters. Each package contains 25 discs, making it a practical unit for shop stock or ongoing job site use. Installation requires a compatible backing pad and angle grinder.

These fiber discs are suited for use in metal fabrication shops, structural steel work, pipeline maintenance, and general industrial grinding applications. The 7-inch diameter and 7/8-inch arbor hole fit standard angle grinders equipped with a matching backing pad. Typical users include ironworkers, pipefitters, welders, and industrial maintenance technicians working on ferrous metal stock removal and surface preparation. This disc size is commonly used where a larger contact area is needed for faster coverage on flat or mildly contoured surfaces.

Compatibility

Designed for use with compatible 7-inch fiber disc backing pads mounted on angle grinders accepting a 7/8-inch arbor. Intended for grinding ferrous metals including steel and iron in fabrication and maintenance applications.

Installation Notes

Fiber discs are installed by licensed or trained operators familiar with angle grinder safety. Power down and disconnect the grinder before mounting or removing the disc. Inspect the backing pad and disc for damage before each use, and confirm the grinder RPM rating meets or exceeds the disc RPM rating. Follow ANSI B7.1 and applicable shop safety standards when operating grinding equipment.
