Norton 66261005491 Deburring Disc 8 in Medium Aluminum Oxide

Product Description

The NORTON 66261005491 is an aluminum oxide deburring disc designed for bench grinder and pedestal grinder applications where edge conditioning, burr removal, and light surface blending are required. It measures 8 inches in diameter with a 1/2 inch arbor center hole and is rated for a maximum of 3000 RPM. The medium grade abrasive provides a balance between material removal and surface finish, making it a practical choice for deburring ferrous and non-ferrous metal workpieces. Machinists, fabricators, and maintenance technicians typically install and use this disc as part of routine edge preparation workflows.

This deburring disc is suited for metal fabrication shops, manufacturing facilities, and maintenance environments where consistent burr removal from cut, drilled, or stamped parts is needed. It mounts to standard bench or pedestal grinders equipped with a 1/2 inch arbor. The medium grade makes it applicable across a range of common metals including steel and aluminum where moderate stock removal and edge smoothing are the goal.
