Merit Abrasives 66254420274 Deburring Wheel Aluminum Oxide

Product Description

The MERIT ABRASIVES 66254420274 is an aluminum oxide unitized deburring wheel built for use with die grinders in metalworking and finishing applications. At 3 inches in diameter with a 1-inch face width and a 1/4-inch center hole, this wheel mounts directly to standard die grinder arbors. It operates at a maximum rated speed of 18,000 RPM and features a Density 6, fine-grade construction that removes burrs, light scale, and surface irregularities without aggressive material removal. The unitized construction holds abrasive grain throughout the wheel thickness, extending usable life as the wheel wears.

This deburring wheel is suited for light deburring, blending, and surface conditioning on metal parts in fabrication, maintenance, and repair environments. It is compatible with die grinders commonly used by machinists, pipefitters, ironworkers, and industrial maintenance technicians. The 1/4-inch center hole fits the standard mandrel size found on most die grinder accessories. Applications include edge deburring on tubing, plate, castings, and machined components where a controlled, fine-grade finish is required.

Key Features

• Aluminum oxide abrasive material suited for ferrous and non-ferrous metal deburring
• Density 6 unitized construction for consistent performance as the wheel wears down
• Fine grade abrasive for light burr removal and surface blending without heavy stock removal
• 18,000 RPM maximum rated speed compatible with standard die grinder operating speeds
• 3-inch diameter with 1-inch face width and 1/4-inch center hole for direct mandrel mounting

Compatibility

Designed for use with die grinders accepting a 1/4-inch arbor mandrel. Suitable for light deburring and finishing operations on metal workpieces in industrial and trade settings.

Installation Notes

Installation and use should be performed by qualified tradespeople familiar with abrasive wheel safety. Ensure the die grinder is fully powered off and disconnected from its power source before mounting or removing the wheel. Verify that the tool's rated RPM meets or exceeds 18,000 RPM before operation, and confirm the arbor mandrel matches the 1/4-inch center hole. Always inspect the wheel for damage before each use and follow ANSI B7.1 safety standards for abrasive wheel handling and operation.
