Norton 666233-57276 Resin Fiber Disc 24 Grit 5x7/8 in

Product Description

The NORTON 666233-57276 is a Merit series resin fiber disc designed for heavy stock removal on metal and other hard surfaces. Built with an aluminum oxide abrasive grain bonded to a fiber backing, this 24-grit disc is engineered for aggressive grinding and material removal in fabrication, weld grinding, and surface preparation applications. At 5 inches in diameter with a 7/8-inch arbor hole, it fits standard angle grinders and disc grinders common in metal fabrication shops and field work. The coarse 24-grit rating makes it well suited for rapid stock removal where surface finish is a secondary concern.

This disc is a practical choice for professional metalworkers, welders, fabricators, and maintenance technicians who need a reliable, economically priced abrasive for everyday grinding tasks. Typical applications include weld bead removal, deburring, edge grinding, and surface conditioning on ferrous metals. The resin fiber construction provides the rigidity needed to withstand the pressure and heat generated during heavy grinding operations.

Compatibility

Designed for use with standard 5-inch angle grinders and disc grinders equipped with a 7/8-inch arbor. Suitable for grinding ferrous metals, welds, and similar hard surfaces where coarse stock removal is required.

Installation Notes

This disc is installed and serviced by metalworkers, welders, and fabricators using standard angle grinders. Before mounting, confirm the grinder RPM rating meets or exceeds the disc maximum speed rating and that the backing pad is in good condition. Always wear appropriate PPE including eye protection and gloves when operating abrasive discs. Inspect the disc for damage or delamination before each use and discard any disc showing signs of wear through to the fiber backing.
