Merit Abrasives 66254420286 Deburring Wheel 3 Inch

Product Description

The MERIT ABRASIVES 66254420286 is a unitized deburring wheel designed for light material removal, edge blending, and surface finishing on metal workpieces. Built with aluminum oxide abrasive at a Density 2 soft grade, this wheel cuts gently while leaving a consistent fine finish. It measures 3 inches in diameter with a 0.25-inch face width and accepts a 0.25-inch center hole, making it a direct fit for standard die grinder arbors. Rated to 18,000 RPM, it handles the output of most pneumatic and electric die grinders without issue. Machinists, fabricators, and maintenance technicians reach for this type of wheel when deburring drilled or stamped holes, smoothing weld spatter, or prepping parts for coating.

This wheel is suited for use in job shops, maintenance facilities, and fabrication environments where controlled, low-aggression finishing is required. The unitized construction bonds the abrasive throughout the wheel body rather than only on the surface, so performance stays consistent as the wheel wears down. Typical applications include deburring ferrous and non-ferrous metal edges, light blending on aluminum or steel, and finishing work that calls for a fine result without aggressive stock removal. The die grinder compatibility makes it easy to reach confined areas and internal bores.

Key Features

• Aluminum oxide abrasive provides consistent cutting action on ferrous and non-ferrous metals
• Density 2 soft grade suits light deburring and fine finishing without aggressive stock removal
• Unitized wheel construction delivers uniform performance throughout the full service life of the wheel
• 18,000 RPM maximum speed rating matches standard pneumatic and electric die grinder output
• 3-inch diameter with 0.25-inch face width fits compact workspaces and internal features
• 0.25-inch center hole fits standard die grinder mandrels directly

Compatibility

Designed for use with die grinders accepting a 0.25-inch arbor. Confirm the tool spindle speed does not exceed the 18,000 RPM rating of this wheel before mounting.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety. Power down and disconnect the die grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and do not operate above the rated maximum speed. Follow ANSI B7.1 safety requirements for the handling, storage, and use of abrasive wheels.
