Merit Abrasives 66254420279 Unitized Deburring Wheel

Product Description

The MERIT ABRASIVES 66254420279 is a unitized deburring wheel designed for aggressive edge finishing and surface deburring on metal workpieces. Built with aluminum oxide abrasive at a coarse grade and density 8 hard construction, this wheel delivers consistent cut-down and burr removal in demanding shop environments. The unitized construction binds the abrasive fibers together throughout the wheel body, maintaining a uniform cutting action as the wheel wears. At a maximum operating speed of 18,000 RPM, it is suited for high-speed die grinder applications where controlled material removal is required. Metalworking fabricators, tool and die shops, and maintenance technicians are the typical users of this wheel.

This deburring wheel is intended for use with die grinders in both light industrial and job-shop settings. It is well suited for deburring drilled holes, weld spatter removal, edge chamfering, and light surface blending on ferrous and non-ferrous metals. The 3 inch diameter and 1/8 inch face width make it appropriate for getting into tighter contours and part edges where larger wheels cannot reach. The 1/4 inch center hole fits standard die grinder mandrels commonly found in production and maintenance tooling setups.

Key Features

• Aluminum oxide abrasive for consistent cutting action on metal surfaces
• Coarse grade, density 8 hard construction for aggressive burr and edge removal
• Unitized wheel design maintains cutting performance throughout the full wheel life
• Rated to 18,000 RPM maximum operating speed for die grinder use
• 1/4 inch center hole fits standard die grinder mandrels
• Compact 3 inch diameter by 1/8 inch face width for access to tight workpiece geometry

Compatibility

Designed for use with die grinders. The 1/4 inch center hole is compatible with standard die grinder mandrel arbors used in bench-top and handheld pneumatic or electric die grinder configurations.

Installation Notes

Installation should be performed by a qualified machinist or metalworking technician. Before mounting, confirm that the spindle speed of the die grinder does not exceed the 18,000 RPM maximum rated speed of this wheel. Secure the center arbor nut fully before operation and inspect the wheel for any visible damage prior to each use. Always wear appropriate eye protection and follow applicable ANSI B7 safety standards for abrasive wheel mounting and operation.
