Norton 66261170061 Deburring Disc 5 in Coarse Aluminum Oxide

Product Description

The NORTON 66261170061 is a 5-inch diameter deburring disc designed for aggressive surface conditioning and edge deburring on metal workpieces. Built with aluminum oxide abrasive in a coarse grade, this flexible disc cuts quickly through burrs, weld spatter, and light scale. The quick-change center attachment threads onto a 5/8-11 arbor, allowing fast disc swaps without additional hardware. Rated to 10000 RPM, it is suitable for use with standard right-angle grinders and disc sanders. Metalworkers, fabricators, and maintenance technicians install this disc in production and field applications where consistent deburring performance is required.

This deburring disc fits into typical metal fabrication workflows involving structural steel, tubing, plate, and sheet metal. The coarse aluminum oxide construction makes it well suited for removing sharp edges after cutting or drilling operations, as well as blending weld joints before inspection or finishing. The flexible backing conforms to irregular or contoured surfaces, extending its usefulness beyond flat stock. It is packaged individually and is sold as a single unit per order.

Installation Notes

Installation and disc changes should be performed by qualified metalworking or maintenance personnel with the grinder powered off and unplugged. Verify the grinder spindle speed does not exceed the 10000 RPM disc rating before operation. Inspect the disc for damage before mounting and ensure the 5/8-11 arbor connection is fully seated and secure. Always use appropriate eye protection and follow applicable ANSI B11 or OSHA standards for abrasive wheel use.
