Norton 66261170289 Deburring Disc 7 in Medium Aluminum Oxide

Product Description

The NORTON 66261170289 is a 7-inch diameter deburring disc engineered for aggressive surface conditioning and edge deburring on metal workpieces. Built with aluminum oxide abrasive and rated at a medium grade, it delivers consistent stock removal across a range of ferrous and non-ferrous materials. The flexible construction conforms to irregular surfaces, making it effective on contoured edges and weld seams. The quick-change center hub with a 5/8-11 thread connection allows fast disc swaps without additional hardware. With a maximum operating speed of 85,000 RPM, this disc is suited for high-speed angle grinders and surface conditioning tools used in fabrication and maintenance environments.

This disc is designed for use in metal fabrication shops, maintenance and repair operations, and industrial production settings where consistent deburring and surface prep are required. It handles edge breaking, light blending, and surface oxide removal on steel, aluminum, and similar metals. The flexible disc body allows it to seat evenly on flat and moderately contoured surfaces, reducing gouging risk on finished workpieces. Licensed trades including pipefitters, millwrights, and general maintenance mechanics commonly use this type of disc for pre-weld and post-weld surface conditioning tasks.

Installation Notes

Installation and operation of abrasive discs should be performed by qualified personnel familiar with angle grinder safety protocols. Always power down and disconnect the grinder before mounting or removing the disc. Verify the tool spindle speed does not exceed the disc maximum RPM rating prior to use. Inspect the disc for cracks or damage before each use and discard any disc showing visible defects.
