Merit Abrasives 66254420266 Deburring Wheel 3 Inch Aluminum Oxide

Product Description

The MERIT ABRASIVES 66254420266 is an aluminum oxide unitized deburring wheel designed for light to moderate material removal, edge blending, and surface finishing on metal workpieces. At 3 inches in diameter with a 1/2-inch face width and a 1/4-inch center hole, this wheel mounts directly to die grinders and runs at up to 18,000 RPM. The density 8 hard-grade construction gives the wheel firm, consistent abrasive action, making it well suited for deburring drilled holes, cleaning weld seams, and refining part edges where controlled stock removal is required. Machinists, fabricators, and maintenance technicians are the primary users of this type of wheel.

This deburring wheel is used in light fabrication shops, maintenance and repair operations, and production environments where die grinders are the standard tooling. Its compact 3-inch diameter allows access to confined areas on workpieces. The medium-grade aluminum oxide abrasive and hard density rating make it appropriate for steel, stainless steel, and other ferrous metals where consistent surface conditioning is needed. It is sold individually and is a direct stock item for single-unit replacement needs.

Key Features

• Aluminum oxide abrasive provides durable, consistent cutting action on ferrous metals
• Density 8 hard-grade unitized construction maintains wheel shape under pressure
• 3-inch diameter and 1/2-inch face width suit die grinder applications in tight spaces
• 1/4-inch center hole fits standard die grinder mandrel sizes
• 18,000 RPM maximum speed rating matches common die grinder operating speeds
• Medium abrasive grade balances material removal rate with surface finish quality

Compatibility

Designed for use with die grinders. The 1/4-inch center hole and 3-inch diameter are compatible with standard die grinder mandrel and arbor configurations used in that tool category.

Installation Notes

Installation and use should be performed by a qualified machinist, fabricator, or maintenance technician familiar with abrasive wheel safety. Before mounting, inspect the wheel for cracks or damage and verify the tool spindle speed does not exceed the 18,000 RPM maximum rating marked on the wheel. Always power down and disconnect the die grinder from its air or electrical supply before mounting or removing the wheel. Use appropriate eye protection, hearing protection, and gloves during operation in accordance with applicable shop safety standards.
