Norton 66254428239 Deburring Disc 3 in Medium Aluminum Oxide

Product Description

The NORTON 66254428239 is an aluminum oxide deburring disc designed for material finishing and edge preparation in metal fabrication and light manufacturing applications. At 3 inches in diameter and 3/16 inch thick, this disc mounts via a quick-change connector, allowing fast swap-outs without additional hardware. The medium grade abrasive delivers consistent stock removal on burrs, sharp edges, and surface irregularities left by cutting, drilling, or stamping operations. With a density rating of 7 to 9, the disc offers a firm, controlled cut suitable for ferrous and non-ferrous metals. Fabricators, machinists, and maintenance technicians are the primary users of this type of consumable abrasive.

This deburring disc is suited for bench grinder, angle grinder, or die grinder applications where a quick-change arbor or mandrel is already in use. It is well-matched to deburring tasks on sheet metal, structural steel, aluminum plate, and similar workpieces in job shop, HVAC fabrication, and general industrial maintenance settings. The 3-inch diameter fits compact tooling setups where access to tight areas or small workpiece features is required. Sold individually, it is a direct replacement consumable for ongoing deburring programs.

Key Features

• Aluminum oxide abrasive material for durable, consistent stock removal on metal surfaces
• Medium grade provides balanced cut rate and surface finish for general deburring tasks
• Quick-change connector allows tool-free disc swaps on compatible mandrels
• 3-inch diameter suits compact grinders and confined-area deburring applications
• 3/16-inch thickness with density rating of 7 to 9 delivers controlled, firm abrasive action

Compatibility

Designed for use with quick-change mandrels and compatible die grinders or angle grinders that accept 3-inch quick-change abrasive discs.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians familiar with portable abrasive tooling. Ensure the grinder is powered off and disconnected from its power source before mounting or removing the disc. Verify that the quick-change mandrel is rated for the operating speed of the grinder in use, and confirm the disc speed rating meets or exceeds the tool RPM before operation. Wear appropriate PPE including eye protection and gloves when handling and operating abrasive discs.
