Norton 66261090909 Deburring Disc 3 in Medium Aluminum Oxide

Product Description

The NORTON 66261090909 is a quick-change deburring disc designed for edge finishing, burr removal, and light surface blending on metal workpieces. At 3 inches in diameter and 1/8 inch thick, this disc mounts to quick-change backup pads for fast, tool-free swaps during production or repair work. The abrasive material is aluminum oxide at a medium grade with a density rating of 7 to 9, delivering consistent cut and controlled aggressiveness on ferrous and non-ferrous metals. Machinists, fabricators, and maintenance technicians use this disc for deburring drilled holes, chamfered edges, and weld seams without removing the workpiece from the fixture.

This deburring disc is suited for bench grinder attachments, right-angle die grinders, and portable finishing tools equipped with a compatible quick-change arbor system. It is commonly used in metal fabrication shops, MRO environments, and light manufacturing where consistent burr removal is required between operations. The quick-change connector reduces disc swap time significantly, making it practical for high-turnover finishing tasks on steel, aluminum, and similar materials.

Installation Notes

Installation is performed by qualified machinists or fabricators using a compatible quick-change backup pad rated for the disc diameter. Ensure the grinder or die grinder is powered off and disconnected from air or electrical supply before mounting or removing the disc. Inspect the backup pad for wear or damage before each disc change. Always operate within the maximum RPM rating of the backup pad and follow applicable ANSI B7.1 safety standards for abrasive product use.
