Norton 66261023949 Deburring Disc 4.5 in Aluminum Oxide

Product Description

The NORTON 66261023949 is an aluminum oxide deburring disc designed for aggressive edge and surface finishing on metal workpieces. At 4.5 inches in diameter, it mounts via a 5/8-11 arbor connection and is rated for a maximum speed of 12000 RPM. The medium grade abrasive delivers consistent material removal for deburring, blending, and light surface conditioning tasks. It is well suited for metal fabrication shops, maintenance facilities, and production environments where a reliable, repeatable deburring solution is required on angle grinders or compatible disc tools.

This deburring disc is intended for use on ferrous and non-ferrous metals in light industrial and fabrication settings. Typical applications include removing burrs from cut edges, weld spatter cleanup, and surface prep before coating or assembly. The 5/8-11 threaded arbor connection is the standard fit for most 4.5-inch angle grinders used by metalworkers and maintenance technicians. It is sold individually but carries a minimum order quantity of 10 units, making it suitable for stocking in tool cribs or supply rooms.

Installation Notes

Installation should be performed by a qualified metalworker or maintenance technician familiar with angle grinder safety procedures. Always power down and disconnect or lock out the tool before mounting or removing the disc. Verify the grinder spindle speed does not exceed the 12000 RPM maximum disc rating before operation. Inspect the disc for damage before each use and follow all applicable ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
