Merit Abrasives 66261054180 Deburring Wheel 3 Inch Unitized

Product Description

The MERIT ABRASIVES 66261054180 is a unitized deburring wheel designed for edge finishing, light deburring, and surface blending on metal workpieces. Built with aluminum oxide abrasive at a fine grade and density 4 soft rating, it delivers consistent, controlled material removal without aggressive cutting action. The wheel measures 3 inches in diameter with a 0.25-inch face width and a 0.25-inch center hole, making it compatible with standard die grinder mandrels. Rated to 12,000 RPM, it suits high-speed rotary tool use in fabrication, maintenance, and light metalworking applications.

This wheel is intended for use with die grinders in workshop and field settings where precise deburring or edge-breaking is required. The unitized construction bonds the abrasive throughout the wheel body, allowing it to cut consistently as it wears rather than glazing over. Typical applications include deburring drilled holes, blending weld seads, and cleaning up machined edges on ferrous and non-ferrous metals. Metalworkers, fabricators, and maintenance technicians in industrial and trade environments are the primary users of this wheel type.

Key Features

• Aluminum oxide abrasive for reliable cutting on ferrous and non-ferrous metals
• Fine grade, density 4 soft construction for controlled, low-aggression material removal
• Unitized wheel design cuts consistently throughout the full wheel life
• 12,000 RPM maximum speed rating suits standard die grinder operating ranges
• 0.25-inch center hole fits common die grinder mandrel sizes
• Compact 3-inch diameter for access to tight or confined work areas

Compatibility

Designed for use with die grinders accepting a 0.25-inch center hole mandrel. Confirm that the grinder spindle speed does not exceed the 12,000 RPM maximum rating before use.

Installation Notes

Mounting and operation should be performed by personnel familiar with rotary abrasive tooling and applicable ANSI B7 safety standards. Power down and disconnect the die grinder before mounting or removing the wheel. Verify the mandrel is secure and the wheel is seated flush before running the tool. Never exceed the 12,000 RPM maximum speed rating marked on the wheel.
