Merit Abrasives 66254420280 Deburring Wheel 6 in Density 8

Product Description

The MERIT ABRASIVES 66254420280 is a unitized aluminum oxide deburring wheel designed for edge blending, light deburring, and surface conditioning on metal workpieces. Running at a maximum of 5,000 RPM, this 6-inch diameter wheel features a density grade of 8 with a hard, coarse abrasive construction that aggressively removes burrs while maintaining consistent wheel integrity over repeated use. The 1-inch face width and 1-inch center hole size make it straightforward to mount on standard bench and pedestal grinder arbors. It is suited for shop technicians and machinists who need a reliable, conformable abrasive wheel for ferrous and non-ferrous material finishing tasks.

This wheel is intended for use on bench grinders and pedestal grinders in machine shops, maintenance facilities, fabrication shops, and industrial service environments. The unitized construction allows the wheel to break down gradually and evenly, providing consistent cutting action throughout the wheel's life. It is well suited for deburring drilled holes, cleaning weld spatter, and blending edges on steel, aluminum, and similar metals. The coarse grade makes it appropriate for initial deburring passes where stock removal rate is the priority.

Installation Notes

Mounting and operation of abrasive wheels should be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and disconnect the grinder from its power source before mounting or removing the wheel. Confirm that the grinder spindle speed does not exceed the 5,000 RPM maximum rating marked on the wheel before starting the machine. Inspect the wheel for visible cracks or damage before each use, and never force a wheel onto an arbor that does not provide a proper fit.
