Norton 66261020548 Deburring Disc 4.5in Medium Aluminum Oxide

Product Description

The NORTON 66261020548 is an aluminum oxide deburring disc designed for grinding, deburring, and surface conditioning on metal workpieces. At 4-1/2 inches in diameter with a 7/8 inch arbor hole, this disc mounts directly to standard angle grinders and right-angle disc grinders. The medium grade abrasive provides an effective cut rate for removing burrs, weld spatter, and sharp edges without excessive material removal. Fabricators, pipefitters, and maintenance technicians working on ferrous and non-ferrous metals are the primary users. The aluminum oxide abrasive is a reliable general-purpose mineral suited for steel, stainless, and cast iron applications.

This deburring disc is suited for light fabrication shops, maintenance and repair operations, and field work where an angle grinder is the primary tool. Typical applications include post-weld cleanup, edge finishing on cut plate and pipe, and deburring drilled or punched holes. The 1-inch thickness provides added rigidity compared to thin cut-off wheels, making it appropriate for surface blending work rather than slotting or cutting.

Key Features

• Aluminum oxide abrasive mineral for general-purpose metal deburring and surface conditioning
• Medium grade provides a balance of stock removal rate and surface finish
• 4-1/2 inch diameter fits standard 4-1/2 inch angle grinders
• 7/8 inch arbor hole for direct mount on most angle grinder spindles
• 1-inch disc thickness adds rigidity for surface blending tasks

Compatibility

Designed as an OEM-style replacement deburring disc for use with standard 4-1/2 inch angle grinders and right-angle disc grinders accepting a 7/8 inch arbor mounting.

Installation Notes

Installation should be performed by qualified fabricators or tradespeople familiar with abrasive wheel mounting procedures. Always power down and unplug or lock out the grinder before mounting or removing a disc. Confirm the tool's maximum RPM rating meets or exceeds the disc's rated speed before operation, and inspect the disc for cracks or damage prior to each use. Operators should wear appropriate PPE including eye protection and gloves during disc changes and operation.
