Norton 66254427991 Fiber Disc 36 Grit 5 Inch Ceramic Alumina

Product Description

The NORTON 66254427991 is a 5-inch ceramic alumina fiber disc from the RazorStar series, designed for aggressive material removal in grinding and blending applications. With a coarse 36-grit abrasive and a coated abrasive type on a fabric backing, this disc cuts fast and holds up under sustained pressure. It mounts via a 7/8-inch arbor hole and is rated to a maximum of 10,000 RPM. Metalworkers, fabricators, and maintenance technicians use this disc on angle grinders for weld removal, surface preparation, and rust elimination on steel and other metals.

This disc is suited for heavy-duty material removal on ferrous metals in both shop and field environments. The ceramic alumina grain self-sharpens as it wears, maintaining cut rate longer than standard aluminum oxide discs. It is appropriate for use in fabrication shops, structural steel work, and maintenance grinding tasks where consistent stock removal is required. The yellow color provides quick visual identification during tool changes.

Installation Notes

Installation should be performed by a qualified operator familiar with angle grinder safety procedures. Always disconnect or de-energize the grinder before mounting or removing a disc. Verify the grinder spindle speed does not exceed the 10,000 RPM maximum disc rating before operation. Inspect the disc for cracks or damage before each use and do not use damaged discs.
