Merit Abrasives 66254420283 Unitized Deburring Wheel

Product Description

The MERIT ABRASIVES 66254420283 is a unitized aluminum oxide deburring wheel designed for light material removal, edge blending, and surface conditioning on metal workpieces. Measuring 2 inches in diameter with a 1/4-inch face width and a 1/4-inch center hole, it mounts directly onto die grinders for fast, repeatable results. The wheel carries a Density 6 rating with a fine abrasive grade, making it well suited for controlled deburring where surface finish matters. A maximum operating speed of 22,000 RPM keeps it compatible with standard die grinder outputs. Metalworkers and fabricators rely on this wheel type for production deburring, weld blending, and part cleanup tasks.

This unitized deburring wheel is used in metal fabrication shops, maintenance and repair operations, and manufacturing environments where consistent edge treatment is required. It is sized for handheld die grinder applications, making it practical for both bench work and in-place deburring on assemblies. The 2-inch diameter is a common fit for tight-radius work and internal edge cleanup. Typical users include machinists, fabricators, and tool-and-die technicians working on ferrous and non-ferrous metal components.

Key Features

• Aluminum oxide abrasive material for reliable cutting action on a wide range of metals
• Density 6 unitized construction maintains consistent wheel shape and abrasive exposure throughout the wheel life
• Fine abrasive grade delivers controlled material removal with a smooth resulting finish
• Rated to 22,000 RPM for compatibility with standard die grinders
• 1/4-inch center hole fits standard die grinder mandrels directly
• Compact 2-inch diameter with 1/4-inch face width suited for detail and edge work

Compatibility

Designed for use with die grinders. The 1/4-inch center hole is compatible with standard die grinder mandrels. Verify your grinder spindle speed does not exceed 22,000 RPM before mounting.

Installation Notes

This wheel is installed by a machinist or fabricator using a compatible mandrel on a die grinder. Before mounting, confirm the grinder speed rating does not exceed the 22,000 RPM maximum marked on the wheel. Always inspect the wheel for damage before use and ensure the mandrel nut is properly secured. Operate with appropriate eye and face protection in accordance with ANSI safety standards for abrasive wheel use.
