Norton 666233-57286 Fiber Disc 7 in 60 Grit 25 Pack

Product Description

The NORTON 666233-57286 is an aluminum oxide fiber disc designed for aggressive material removal on metal, weld seams, and other hard surfaces. Built on the Merit FX370 fiber backing, this disc measures 7 inches in diameter with a 7/8-inch arbor hole and carries a 60 grit designation, placing it in the coarse range for rapid stock removal and surface conditioning. It is sold in a pack of 25 discs, making it a practical choice for shops and field crews that burn through abrasives at volume. Metal fabricators, welders, pipefitters, and maintenance trades rely on fiber discs like this for grinding, blending, and cleaning operations with angle grinders and disc grinders.

This fiber disc is suited for use in industrial, commercial, and heavy-trade environments where consistent cutting action across multiple passes is required. Typical applications include weld bead removal, rust and scale removal, and general stock removal on ferrous and non-ferrous metals. The 60 grit cut makes it appropriate as an initial grinding step before moving to finer abrasives for finishing work. It is commonly found on job sites, fabrication shops, and maintenance facilities where angle grinder work is a daily operation.

Key Features

• Aluminum oxide abrasive grain for durable, consistent cutting performance on metal surfaces
• Merit FX370 fiber backing provides rigidity and resistance to flex during aggressive grinding
• 60 grit coarse cut for rapid stock removal and weld seam grinding

Compatibility

Designed for use with angle grinders and disc grinders fitted with a compatible 7-inch fiber disc backing pad and a 7/8-inch arbor. Intended for use on metal grinding and surface preparation applications.

Installation Notes

Fiber discs are installed by a backing pad matched to the disc diameter and arbor size — confirm the backing pad rating meets or exceeds the grinder RPM before mounting. Always inspect the disc for damage before use and never operate a damaged disc. Wear appropriate PPE including eye protection and gloves during grinding operations. Follow the grinder and abrasive manufacturer guidelines for maximum operating speed and safe work practices.
