Norton 66261170063 Deburring Disc 5 in Medium Aluminum Oxide

Product Description

The NORTON 66261170063 is a 5-inch diameter flexible deburring disc designed for surface conditioning, edge blending, and light stock removal on metal workpieces. Constructed with aluminum oxide abrasive at a medium grade, it is engineered to remove burrs, sharp edges, and light surface imperfections without aggressive material removal. The quick-change center connector threads onto a 5/8-11 arbor, allowing fast disc swaps without tools. Rated to a maximum of 10,000 RPM, this disc suits both bench and angle grinder applications used by machinists, fabricators, HVAC sheet metal workers, and pipe fitters performing prep and finishing work on metal components.

This deburring disc is suited for use on ferrous and non-ferrous metals in light industrial and trade applications. Common scenarios include deburring cut pipe ends, cleaning up drilled or punched holes, and blending weld seams before inspection or assembly. The flexible disc conforms modestly to contoured surfaces, making it useful where rigid abrasives would leave flat spots. Sold individually, it is a direct replacement consumable for shops and service vans stocking standard 5-inch quick-change abrasive tooling.

Installation Notes

Installation is performed by trade professionals including machinists, pipefitters, and HVAC sheet metal technicians. Before mounting, ensure the tool is powered off and the power source is disconnected or locked out per OSHA lockout/tagout procedures. Thread the disc securely onto the 5/8-11 arbor and verify it is fully seated before operation. Do not exceed the 10,000 RPM maximum speed rating marked on the disc.
