Merit Abrasives 66254420267 Deburring Wheel 3 Inch

Product Description

The MERIT ABRASIVES 66254420267 is a unitized aluminum oxide deburring wheel designed for use with die grinders in metal finishing and deburring applications. With a density rating of 8 and a hard grade classification, this wheel delivers firm, consistent abrasive action for removing burrs, sharp edges, and light surface imperfections from metal workpieces. The wheel measures 3 inches in diameter with a 1-inch face width and mounts on a 1/4-inch center hole, fitting standard die grinder arbors. It is rated to a maximum of 18,000 RPM. Metalworkers, fabricators, and maintenance technicians use this type of wheel for edge finishing on steel, aluminum, and similar metals.

This deburring wheel is suited for shop and field use where a die grinder is the primary tool. The unitized construction bonds abrasive fibers throughout the wheel body, providing consistent cut throughout the wheel life rather than only at the surface. Typical applications include deburring drilled holes, blending weld seams, and cleaning up machined edges on metal parts. It is appropriate for both production and maintenance environments handling ferrous and non-ferrous metals.

Compatibility

Designed for use with die grinders accepting a 1/4-inch arbor. Verify tool RPM rating meets or exceeds 18,000 RPM before mounting.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety. Always confirm the die grinder is unplugged or de-energized before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and never operate above the rated maximum RPM. Follow ANSI B7.1 and tool manufacturer guidelines for proper wheel mounting and guard use.
