Norton 666233-55595 Ceramic Alumina Fiber Disc 7 in 50 Grit

Product Description

The NORTON 666233-55595 is a 7-inch ceramic alumina fiber disc engineered for aggressive material removal and surface finishing on metal. Running on a ceramic alumina abrasive grain, this disc delivers consistent cut rates and extended service life compared to standard aluminum oxide options. At 50 grit, it is suited for heavy stock removal, weld blending, and edge deburring. The 7/8-inch arbor hole fits standard right-angle grinders used by fabricators, pipefitters, ironworkers, and maintenance professionals who demand reliable abrasive performance in production and field environments.

This disc is designed for use on steel, stainless steel, and other ferrous metals where aggressive grinding is required. The 50-grit cut is appropriate for initial weld seam blending, scale removal, and surface prep before secondary finishing steps. It ships and is sold in a package quantity of 25 discs, making it suitable for shop stock and ongoing production use. Typical applications include structural fabrication, pressure vessel work, and general metal surface preparation.
