Norton 66261004021 Deburring Wheel 6 in Silicon Carbide

Product Description

The NORTON 66261004021 is a convolute deburring wheel built for bench grinders and pedestal grinders. It uses silicon carbide abrasive in a hard, density-9 construction that aggressively removes burrs, sharp edges, and surface contamination from metal workpieces. At 6 inches in diameter with a 0.5-inch face width and a 1-inch center hole, it mounts directly to standard grinder arbors. Rated to 6,000 RPM, this wheel suits production and maintenance grinding environments where consistent deburring and edge conditioning are required. Machinists, tool and die workers, and maintenance technicians are the typical users.

This convolute wheel is suited for deburring, edge blending, and light surface conditioning on metal parts in both shop and production settings. The fine-grade silicon carbide abrasive cuts cleanly on ferrous and non-ferrous metals without loading quickly. Its convolute construction — layers of abrasive-coated material wound around a core — provides a consistent cut throughout the life of the wheel, unlike surface conditioning discs that wear unevenly. It is well-matched to bench grinder stations used for finishing machined components or cleaning up fabricated parts before inspection or assembly.

Key Features

• Silicon carbide abrasive for effective cutting on ferrous and non-ferrous metals
• Density 9 hard grade convolute construction for consistent material removal
• Fine abrasive grade suited for deburring and edge conditioning without aggressive stock removal
• 6,000 RPM maximum speed rating for use on standard bench and pedestal grinders
• 1-inch center hole fits common grinder arbor sizes
• Convolute wheel design maintains consistent cut as the wheel wears

Compatibility

Designed for use with bench grinders and pedestal grinders. The 1-inch center hole and 6-inch diameter are standard dimensions for these machine types. Verify arbor size and maximum RPM rating of the grinder before mounting.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety. Power down and lock out the grinder before mounting or removing the wheel. Confirm the grinder spindle speed does not exceed the 6,000 RPM maximum marked on the wheel — operating above rated speed is a serious safety hazard. Inspect the wheel for cracks or damage before each use, and allow the wheel to run at operating speed in a guarded position for at least one minute before applying it to a workpiece.
