Merit Abrasives 66254420268 Unitized Deburring Wheel 3 Inch

Product Description

The MERIT ABRASIVES 66254420268 is an aluminum oxide unitized deburring wheel designed for edge blending, light deburring, and surface conditioning on metal workpieces. It measures 3 inches in diameter with a 1-inch face width and a 1/4-inch center hole, fitting standard die grinder mandrels. Rated to 18,000 RPM, the wheel uses a density 8, hard-grade construction that delivers consistent cut and finish throughout the wheel's life. It is sold individually and suited for shop technicians and machinists who need a reliable, quick-change abrasive for finishing work.

This unitized deburring wheel is used in metal fabrication, maintenance, and repair environments where controlled material removal is required on steel, aluminum, and similar metals. The medium-grade aluminum oxide abrasive is well-matched to die grinder applications, including deburring drilled holes, cleaning weld spatter, and blending sharp edges on machined or cut parts. Its compact 3-inch diameter allows access to tight areas that larger flap discs or grinding wheels cannot reach.

Key Features

• Aluminum oxide abrasive with medium grade and density 8 hard construction for consistent stock removal
• 3-inch diameter with 1-inch face width for effective surface contact on flat and contoured workpieces
• 1/4-inch center hole for direct mounting on standard die grinder mandrels
• 18,000 RPM maximum speed rating matches common die grinder operating ranges
• Unitized wheel construction maintains uniform cut rate as the wheel wears

Compatibility

Designed for use with die grinders accepting a 1/4-inch arbor. The 18,000 RPM rating is compatible with most standard pneumatic and electric die grinders used in metalworking and fabrication applications.

Installation Notes

Installation is performed by threading the wheel onto an appropriate die grinder mandrel sized for a 1/4-inch center hole. Always confirm the tool's rated RPM does not exceed the wheel's 18,000 RPM maximum before operation. Wear appropriate eye protection and a face shield when mounting and running abrasive wheels. Inspect the wheel for cracks or damage before each use and never operate a damaged wheel.
