Norton 66261004284 Convolute Deburring Wheel 12 Inch

Product Description

The NORTON 66261004284 is a convolute deburring wheel designed for aggressive edge blending, deburring, and surface finishing on metal workpieces. Built with silicon carbide abrasive at a density grade of 8 (hard), this wheel delivers consistent cutting action across its full 1-inch face width. The fine abrasive grade makes it well suited for finishing passes where removing sharp burrs without heavy stock removal is the priority. It is rated to a maximum of 3,000 RPM and mounts on a 5-inch center hole, fitting standard bench and pedestal grinder arbors. Machinists, fabricators, and metalworking shops are the primary users of this wheel.

This wheel is intended for use on bench grinders and pedestal grinders in metalworking, fabrication, and light industrial environments. At 12 inches in diameter with a 1-inch face width, it covers a substantial work area per pass, reducing cycle time when deburring production runs of machined or stamped parts. The convolute construction — layers of abrasive-impregnated non-woven material wound into a dense roll — maintains consistent abrasive exposure as the wheel wears, providing predictable performance through the life of the wheel.

Key Features

• Silicon carbide abrasive for sharp, fast cutting action on ferrous and non-ferrous metals

• Fine abrasive grade suited for deburring and edge blending without excessive stock removal
• 12-inch diameter with 1-inch face width provides broad contact area per pass
• 5-inch center hole fits standard bench and pedestal grinder arbors
• 3,000 RPM maximum speed rating

Compatibility

Designed for use with bench grinders and pedestal grinders accepting a 5-inch center hole arbor and rated to accommodate a 12-inch diameter wheel at up to 3,000 RPM.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician. Always power down and lock out the grinder before mounting or removing the wheel. Verify that the grinder spindle speed does not exceed the 3,000 RPM maximum rating of this wheel before operation. Inspect the wheel for cracks or damage before mounting, and use the correct blotter and flange hardware per ANSI B7.1 safety requirements for abrasive wheels.
