Norton 666233-65598 Ceramic Alumina Fiber Disc 80 Grit 25 Pack

Product Description

The NORTON 666233-65598 is a ceramic alumina fiber disc engineered for aggressive material removal and long service life on metal fabrication applications. Measuring 4.5 inches in diameter with a 0.875-inch arbor hole, this disc mounts directly to standard angle grinders and disc grinders. The 80-grit ceramic alumina abrasive cuts faster and runs cooler than conventional aluminum oxide, extending disc life and reducing operator fatigue on heavy grinding, weld blending, and surface conditioning tasks. Sold in a 25-disc package, it suits shops and field crews that cycle through abrasives at volume.

This disc is suited for use on mild steel, stainless steel, and other ferrous metals in structural fabrication, pipe preparation, and general metalworking environments. The 4.5-inch format is a standard size for the most common angle grinder class used by ironworkers, welders, pipefitters, and metal fabrication technicians in both shop and field settings. The 80-grit designation provides a balance of cut rate and surface finish appropriate for weld removal and pre-weld surface prep.

Key Features

• Ceramic alumina abrasive grain for fast cutting and extended disc life compared to conventional aluminum oxide
• 80-grit designation balances aggressive stock removal with acceptable surface finish
• 4.5-inch diameter with 0.875-inch arbor hole fits standard angle grinders
• Merit FX965 product line construction for consistent grain orientation and backing integrity
• Sold in 25-disc packs to support high-volume production and field use

Compatibility

Designed for use with standard 4.5-inch angle grinders and disc grinders accepting a 0.875-inch arbor. Suitable for grinding and finishing ferrous metal surfaces in fabrication and maintenance applications.

Installation Notes

Fiber discs must be installed on a properly rated backing pad matched to the disc diameter before mounting on the grinder. Verify that the grinder RPM rating meets or exceeds the disc maximum RPM before operation. Always power down and disconnect the tool from its power source before changing discs. Wear appropriate PPE including face shield, gloves, and hearing protection during use, per ANSI B7.1 and applicable workplace safety standards.
