Merit Abrasives 66254420292 Deburring Wheel Silicon Carbide

Product Description

The MERIT ABRASIVES 66254420292 is a unitized deburring wheel designed for light material removal, surface blending, and edge finishing on metal workpieces. Built with silicon carbide abrasive at a density grade of 6 (medium), this wheel delivers consistent cut and finish on harder materials including cast iron, titanium, and non-ferrous metals. It measures 2 inches in diameter with a 0.5-inch face width and a 0.25-inch center hole, fitting standard die grinder mandrels. Rated to 22,000 RPM, it is suited for high-speed finishing work in fabrication, maintenance, and machine shop environments. Installation and operation are handled by machinists, fabricators, and tool-and-die tradespeople.

This wheel is used in situations requiring controlled deburring or edge blending on parts that cannot tolerate aggressive stock removal. Its unitized construction integrates abrasive throughout the wheel body rather than just on the surface, meaning the cut characteristics remain consistent as the wheel wears. Typical applications include deburring drilled or punched holes, light surface preparation before inspection, and finish blending on weld zones. The compact 2-inch diameter allows access to confined areas and intricate part geometries where larger wheels cannot reach.

Key Features

• Silicon carbide abrasive construction suitable for hard metals and non-ferrous materials
• Density grade 6 medium for a balance of cut aggressiveness and surface finish
• Unitized wheel design provides consistent abrasive performance throughout the wheel life
• 22,000 RPM maximum speed rating compatible with standard die grinder operating ranges
• 0.25-inch center hole fits common die grinder mandrels without adapters
• Compact 2-inch diameter allows work in tight spaces and on detailed part features

Compatibility

Designed for use with die grinders accepting a 0.25-inch center hole mandrel. Verify that the grinder speed does not exceed the 22,000 RPM maximum rating before mounting.

Installation Notes

This wheel is installed and operated by machinists, fabricators, or maintenance technicians using a die grinder. Power off and disconnect the grinder from its air or electrical supply before mounting or removing the wheel. Confirm the spindle speed rating of the tool does not exceed 22,000 RPM. Always inspect the wheel for cracks or damage before use and wear appropriate eye and face protection during operation.
