Norton 66623374819 Deburring Disc 5 in Medium Aluminum Oxide

Product Description

The NORTON 66623374819 is a 5-inch diameter deburring disc engineered for material removal, edge blending, and surface conditioning on metal workpieces. Built with aluminum oxide abrasive in a medium grade, it delivers consistent cut rate across a range of ferrous and non-ferrous metals. The quick-change connector design allows fast disc swaps without additional hardware, reducing downtime during production or field work. A 5/8-11 threaded center hole provides secure mounting to compatible angle grinders and disc systems. This disc is installed and used by machinists, pipefitters, fabricators, and HVAC sheet metal technicians working on edge prep and deburring tasks.

This deburring disc is suited for shop and field applications where burrs, sharp edges, and surface scale need to be removed from cut or drilled metal. Common scenarios include pipe end preparation, tube deburring after cutting, and weld seam blending on structural or mechanical assemblies. The medium grade aluminum oxide construction makes it a practical choice for general-purpose deburring across mild steel, stainless steel, and aluminum substrates.

Installation Notes

Installation and use of grinding and deburring discs should be performed by qualified personnel following ANSI B7.1 safety standards for abrasive wheel use. Ensure the grinder is powered off and disconnected from its power source before mounting or removing the disc. Verify that the grinder RPM rating meets or exceeds the disc maximum speed rating before operation. Always use appropriate PPE including eye protection and gloves when operating abrasive discs.
