Norton 662531-46922 Fiber Disc 80 Grit 4x5/8 Inches

Product Description

The NORTON 662531-46922 is a fiber-backed abrasive disc designed for aggressive material removal on metal, weld seams, and surface preparation applications. Running at 80 grit, this disc cuts through mild steel, stainless, and aluminum efficiently while maintaining a consistent scratch pattern. The fiber construction provides the rigidity needed for use with right-angle grinders and disc holders. At 4.2 pounds per unit, the disc is built for sustained production work in fabrication and maintenance settings. Grinding professionals and metal fabricators will find this disc well-suited to stock removal and blending tasks that demand a dependable abrasive.

This fiber disc is intended for use in metalworking and fabrication environments, including structural steel work, weld blending, and surface conditioning on ferrous and non-ferrous metals. It is commonly used in shops, field fabrication, and maintenance-repair-overhaul settings. The non-loading formulation helps reduce disc glazing when working softer metals or coated surfaces, extending usable disc life on the job.
