Norton 66261170062 Deburring Disc 4.5in Medium Aluminum Oxide

Product Description

The NORTON 66261170062 is a flexible aluminum oxide deburring disc designed for quick-change angle grinder and disc tool applications. Measuring 4-1/2 inches in diameter, this medium-grade abrasive disc removes burrs, surface scale, and light weld splatter from metal workpieces. The quick-change connector allows for fast, tool-free disc swaps during production or field work. Rated to a maximum of 12,000 RPM, it is suited for use on portable rotary tools common in metal fabrication, maintenance, and industrial finishing environments. Licensed tradespeople and skilled fabricators working on steel and similar metals are the primary installers and operators of this disc.

This deburring disc is used in metal fabrication shops, maintenance and repair operations, and light industrial settings where controlled material removal and surface prep are needed. The flexible construction allows the disc to conform slightly to curved or irregular workpiece surfaces, making it effective on tubular stock, pipe ends, and irregular weldments. It is compatible with quick-change disc systems using a 5/8-11 center hole thread size, which is a standard interface on many angle grinders and right-angle die grinders used in trade environments.

Key Features

• Aluminum oxide abrasive for effective deburring on steel and ferrous metals
• Medium grade provides balanced stock removal and surface finish control
• Quick-change connector for fast, tool-free disc replacement
• Flexible disc construction conforms to irregular and curved surfaces
• 12,000 RPM maximum rated speed for use with standard angle grinders
• 5/8-11 center hole thread size matches common grinder spindle standards

Compatibility

Designed for use with quick-change disc systems accepting a 5/8-11 threaded center hole, standard on many angle grinders and right-angle die grinders used in metal fabrication and maintenance applications.

Installation Notes

This disc is installed and operated by machinists, fabricators, and maintenance technicians working with angle grinders or compatible rotary tools. Before mounting, confirm the tool spindle speed does not exceed the 12,000 RPM disc rating and that the spindle thread matches the 5/8-11 center hole. Always power down and unplug or de-energize the tool before changing discs. Wear appropriate PPE including eye protection and gloves when operating abrasive discs.
