Norton 66261170060 Deburring Disc 4-1/2 in Coarse Aluminum Oxide

Product Description

The NORTON 66261170060 is a flexible aluminum oxide deburring disc designed for aggressive material removal and surface conditioning on metal workpieces. Built for use with quick-change disc systems, this 4-1/2 inch diameter disc runs at up to 12,000 RPM and cuts in a coarse grade — making it effective for removing burrs, flash, and sharp edges left after cutting, stamping, or welding operations. The flexible construction allows the disc to conform to irregular surfaces without gouging. It mounts via a 5/8-11 threaded center hole and is compatible with standard quick-change angle grinder or right-angle die grinder setups used in fabrication and metalworking environments.

This deburring disc suits metalworking professionals, fabricators, and maintenance technicians working on structural steel, pipe, plate, and sheet metal. The coarse grade makes it a practical choice for initial deburring passes where fast stock removal is the priority. At 4-1/2 inches, it fits the most common disc grinder platform used in field and shop work alike. Single-disc packaging makes it straightforward to stock as a replacement or supplement to an existing abrasive inventory.

Installation Notes

Installation should be performed by a qualified metalworking technician or abrasives operator. Always power down and disconnect the grinder from its power source before mounting or removing the disc. Confirm that the tool's rated RPM meets or exceeds the disc's 12,000 RPM maximum before operation. Inspect the disc for damage before each use and follow all applicable ANSI B7 abrasive safety standards.
