Norton 666233-55604 Ceramic Alumina Fiber Disc 60 Grit 25 Pack

Product Description

The NORTON 666233-55604 is a ceramic alumina fiber disc engineered for aggressive material removal on metal, welds, and other hard surfaces. Measuring 4.5 inches in diameter with a 0.875-inch arbor hole, this disc fits standard angle grinders used across fabrication, HVAC, and plumbing trades. The 60-grit ceramic alumina abrasive delivers a fast cut rate with extended disc life compared to conventional aluminum oxide discs. Sold in a package of 25, these discs are well suited for shops and field crews that cycle through abrasives at high volume.

This fiber disc is appropriate for grinding, blending, and deburring operations on ferrous and non-ferrous metals in both residential and commercial work environments. Common applications include weld removal, pipe preparation, and surface conditioning on structural steel, copper, and stainless. The 60-grit designation positions this disc for stock removal rather than fine finishing, making it a first-step abrasive in multi-stage surface prep workflows.

Key Features

• Ceramic alumina abrasive grain for fast cut and long service life
• 60 grit for aggressive stock removal and weld grinding
• 4.5-inch diameter with 0.875-inch arbor hole fits standard angle grinders

Compatibility

Designed as a direct-fit fiber disc for standard angle grinders and disc grinders accepting a 4.5-inch disc with a 0.875-inch arbor hole.

Installation Notes

Fiber discs must be mounted on a matching backing pad rated for the disc diameter before use on an angle grinder. Inspect the disc for cracks or damage before each use and do not exceed the maximum RPM rating marked on the disc or grinder. Operators should wear appropriate PPE including face shield, gloves, and hearing protection during grinding operations. Ensure the grinder guard is in place before powering on the tool.
