Norton 66261018639 Deburring Wheel 8 Inch Silicon Carbide

Product Description

The NORTON 66261018639 is a convolute deburring wheel designed for use on bench grinders and pedestal grinders in metalworking and fabrication environments. Built with a silicon carbide abrasive at a fine grade and density 7 hard rating, this wheel delivers consistent material removal on ferrous and non-ferrous workpieces. At 8 inches in diameter with a 1-inch face width and a 3-inch center hole, it mounts directly to standard grinder arbors. The 3,650 RPM maximum speed rating keeps it compatible with most bench and pedestal grinder configurations found in trade shops, maintenance facilities, and light industrial settings. Licensed machinists, tool-and-die techs, and fabricators rely on convolute wheels for deburring, blending, and light surface conditioning tasks.

This wheel suits applications where controlled, repeatable deburring is required without aggressive stock removal. The convolute construction layers abrasive uniformly throughout the wheel body, maintaining consistent cut characteristics as the wheel wears down. It is a practical fit for shops processing cut pipe, plate edges, castings, or stamped parts that require cleaned edges before assembly or inspection. The silicon carbide abrasive makes it particularly effective on harder non-ferrous metals, cast iron, and non-metallic materials where aluminum oxide abrasives underperform.

Key Features

• Silicon carbide abrasive for effective deburring of hard non-ferrous metals and cast iron
• Density 7 hard grade convolute construction for consistent cut throughout wheel life
• Fine grade abrasive for surface blending and edge conditioning without aggressive stock removal
• 3,650 RPM maximum rated speed for standard bench and pedestal grinder compatibility
• 8-inch diameter with 3-inch center hole for direct arbor mounting on common grinder configurations
• 1-inch face width provides a focused contact zone for edge work and deburring passes

Compatibility

Designed for use with bench grinders and pedestal grinders. Verify that the grinder arbor speed does not exceed the 3,650 RPM maximum rating and that the arbor accepts a 3-inch center hole before mounting.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician following the grinder manufacturer's wheel-mounting procedures. Always disconnect and lock out power to the grinder before changing wheels. Inspect the wheel for cracks or chips before mounting and perform a ring test per ANSI B7.1 guidelines. Never exceed the 3,650 RPM maximum speed rating stamped on the wheel.
