Norton 66261126559 Fiber Disc 60 Grit 5 Inches F826P

Product Description

The NORTON 66261126559 is a 5-inch zirconia alumina fiber disc designed for aggressive material removal on metal, weld seams, and fabricated surfaces. Built on a resinoid bond with a fiber backing, this 60-grit medium-grade disc delivers consistent cut rates on ferrous and non-ferrous metals. It mounts via a threaded arbor hole with a 5/8-11 thread size and is rated to 13,000 RPM, making it a reliable choice for angle grinder work in fabrication, maintenance, and structural steel applications. It is part of the F826P series and is designed for use with the Norton AVOS Speed-Lok Back-Up Pad.

This disc is suited for metal grinding, deburring, and weld blending in both shop and field environments. The 60-grit rating targets general stock removal rather than finishing, making it appropriate for rough surface prep ahead of coating or welding. Fabricators, ironworkers, pipefitters, and maintenance technicians are the primary users. The threaded arbor attachment requires a compatible back-up pad and is not a peel-and-stick or quick-change mount.
