Norton 66254429268 Deburring Disc 4-1/2 in Medium Aluminum Oxide

Product Description

The NORTON 66254429268 is an aluminum oxide deburring disc engineered for edge deburring, surface blending, and light stock removal on metal workpieces. At 4-1/2 inches in diameter with a 7/8 inch center hole, this disc mounts to standard right-angle grinders and deburring tools used in fabrication, maintenance, and production environments. The aluminum oxide abrasive delivers consistent cut on ferrous metals, and the medium grade provides a balanced combination of material removal rate and surface finish. Rated to 12,000 RPM maximum, it is suited for high-speed tool operation. Metal fabricators, pipefitters, and maintenance technicians typically reach for this disc when cleaning up cut edges, weld spatter, and burrs on structural and sheet metal components.

This deburring disc is intended for use in light-duty grinding and surface conditioning applications on metal. It fits standard 4-1/2 inch angle grinders with a 7/8 inch arbor, making it compatible with the most common grinder configurations found in fabrication shops, field service, and plant maintenance settings. The medium grade abrasive suits general deburring and blending tasks where a coarser disc would remove too much material and a fine disc would cut too slowly.

Installation Notes

Mounting and operation of abrasive discs should be performed by qualified personnel following ANSI B7.1 safety standards for grinding wheels and abrasive products. Before mounting, inspect the disc for cracks or damage and confirm the tool spindle speed does not exceed the 12,000 RPM maximum disc rating. Always wear appropriate PPE including a face shield and gloves when operating grinding equipment. Never exceed the maximum RPM rating stamped or listed for any abrasive disc.
