Dewalt DW8404 Aluminum Grinding Wheel 4.5x0.25x0.875 in

Product Description

The DEWALT DW8404 is a bonded abrasive grinding wheel engineered for material removal on aluminum and non-ferrous metals. Measuring 4.5 inches in diameter, 0.25 inches thick, and with a 0.875-inch arbor hole, this wheel mounts to standard 4.5-inch angle grinders used daily in HVAC, plumbing, electrical, and general fabrication work. The bonded abrasive construction delivers consistent stock removal and maintains wheel integrity under sustained grinding pressure. At 0.27 pounds, it adds minimal rotational mass, reducing fatigue during extended use. Licensed tradespeople and experienced fabricators working with aluminum ductwork, pipe, conduit, and structural stock will find this wheel a reliable consumable for routine grinding tasks.

This wheel is suited for grinding aluminum and soft non-ferrous metals in both residential and light commercial applications. Common install scenarios include trimming aluminum duct flanges, deburring cut conduit ends, and surface prep on aluminum structural components. It is sold individually and is a standard consumable for contractors who work frequently with non-ferrous materials on jobsites requiring angle grinder access.

Installation Notes

Mounting and use of abrasive grinding wheels should be performed by qualified tradespeople familiar with angle grinder safety. Always power down and disconnect the grinder from its power source before mounting or removing a wheel. Inspect the wheel for cracks or damage before installation and confirm the grinder's rated RPM meets or exceeds the wheel's maximum RPM rating. Follow applicable ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
