Norton 666233-55601 Ceramic Alumina Fiber Disc 24 Grit

Product Description

The NORTON 666233-55601 is a ceramic alumina fiber disc designed for aggressive material removal on metal surfaces. Measuring 4.5 inches in diameter with a 7/8-inch arbor hole, this disc runs on standard angle grinders and disc sanders used in fabrication, welding prep, and metal finishing applications. The ceramic alumina grain delivers a fast cut rate and resists dulling under sustained pressure, making it a dependable choice for heavy stock removal on steel and other ferrous metals. Sold in a package of 25 discs, the 666233-55601 is suited for professional use in industrial and trade settings.

This disc is commonly used by welders, metal fabricators, and maintenance technicians who need consistent, aggressive cutting action across multiple passes. The 24-grit designation places it at the coarse end of the spectrum, making it most appropriate for weld seam removal, surface conditioning, and deburring tasks where rapid material removal takes priority over surface finish. The 4.5-inch size fits widely available right-angle grinders found on commercial job sites and in shop environments.

Key Features

• Ceramic alumina grain for fast cut rate and extended disc life under pressure
• 24-grit coarse abrasive for aggressive stock removal and weld seam grinding
• 4.5-inch diameter with 7/8-inch arbor hole for standard angle grinder compatibility
• Packaged in quantities of 25 for continuous production and shop use
• Fiber backing provides rigidity and durability during heavy-pressure grinding

Compatibility

Designed as a direct-fit replacement for Merit FX965 fiber discs in the same 4.5-inch by 7/8-inch size. Fits standard right-angle grinders and disc sanders accepting 4.5-inch fiber discs with a 7/8-inch arbor.

Installation Notes

Fiber discs are installed and replaced by metal fabricators and maintenance technicians using standard backing pads rated for the disc diameter. Always power down and unplug or lock out the grinder before mounting or removing a disc. Inspect the backing pad and disc for damage before each use, and ensure the grinder RPM rating meets or exceeds the disc RPM rating. Follow applicable ANSI B7.1 safety standards for the use of abrasive wheels.
