Norton 66623374818 Deburring Disc 5 in Coarse Aluminum Oxide

Product Description

The NORTON 66623374818 is a 5-inch diameter deburring disc engineered for aggressive material removal on metal surfaces. Constructed with aluminum oxide abrasive, this coarse-grade disc cuts quickly through burrs, sharp edges, and surface scale left behind by cutting, drilling, or grinding operations. The quick-change connector allows fast disc swaps without tools, reducing downtime during production or fieldwork. It is designed for use with compatible right-angle grinders and disc holders equipped with a 5/8-11 threaded center. Metal fabricators, pipefitters, and maintenance trades rely on this type of disc for deburring, blending, and light surface prep work.

This deburring disc suits both shop and field applications where consistent edge finishing is required on ferrous and non-ferrous metals. The coarse grade makes it well suited for initial deburring passes on heavier stock, weld cleanup, and removal of machining burrs prior to assembly or inspection. The quick-change mount is compatible with standard disc pad holders that accept the 5/8-11 thread specification.

Installation Notes

Installation and disc changes should be performed with the grinder unplugged or the power source locked out per standard lockout/tagout procedures. Verify the disc holder thread size matches the 5/8-11 center before mounting. Always confirm the tool RPM rating meets or exceeds the disc rating before operation. Wear appropriate PPE including eye protection and gloves when operating abrasive discs.
