Merit Abrasives 66254420278 Deburring Wheel 2 in Aluminum Oxide

Product Description

The MERIT ABRASIVES 66254420278 is a unitized deburring wheel designed for edge finishing, light deburring, and surface blending on metal workpieces. Built with aluminum oxide abrasive at a hard density grade of 8, it delivers consistent cut and finish across ferrous and non-ferrous metals. The wheel measures 2 inches in diameter with a 1/8-inch face width and accepts a 1/4-inch center arbor. Rated to 22,000 RPM, it is matched for use with die grinders in industrial maintenance, fabrication, and machine shop applications. Installers and technicians rely on this type of wheel for controlled, repeatable deburring without loading or glazing.

This unitized wheel is suited to bench-top die grinder setups and handheld pneumatic or electric die grinders used in fabrication shops, maintenance facilities, and production lines. The coarse, hard grade makes it effective on steel, aluminum, and similar metals where edge cleanup and light surface conditioning are required. Its compact 2-inch diameter fits into tight part geometries and inside bores where larger wheels cannot reach.

Key Features

• Aluminum oxide abrasive construction for consistent cut on ferrous and non-ferrous metals
• Density 8 hard grade provides firm, controlled material removal with minimal deflection
• 22,000 RPM maximum rating compatible with standard die grinder operating speeds
• 2-inch diameter and 1/8-inch face width suit tight workpiece geometries
• 1/4-inch center hole mounts directly to standard die grinder mandrels
• Unitized construction resists loading and maintains consistent surface contact throughout wheel life

Compatibility

Designed for use with die grinders accepting a 1/4-inch arbor mandrel. Tooling compatibility is specified for die grinders.

Installation Notes

Mounting and operation of abrasive wheels should follow ANSI B7.1 safety standards and the grinder manufacturer guidelines. Always power down and disconnect the die grinder before mounting or changing the wheel. Verify the tool's free-speed RPM does not exceed the wheel's 22,000 RPM maximum rating before operating. Use the appropriate mandrel size and ensure the wheel seats fully and runs true before applying it to the workpiece.
