The DEWALT DW4771 7-Inch Grinding Cup Wheel is a general-purpose cup wheel built for right-angle grinders. Whether you are smoothing welds, prepping metal, or shaping concrete and masonry, this 7-inch wheel uses a durable abrasive bond to remove material quickly and leave a consistent surface. It’s a straightforward choice for pros and serious DIYers who want reliable grinding without re-inventing their setup.
DEWALT DW4771 7-Inch Grinding Cup Wheel: General-Purpose Grinding Performance
The DW4771 is designed around the working needs of fabricators and concrete crews. Its cup-style shape puts more abrasive in contact with the work piece, so you can flatten, clean, and shape surfaces faster than with a standard flat wheel. The 5/8-11 arbor fits most 7-inch angle grinders; always match the wheel’s max RPM to your grinder before mounting.
Metal, Masonry, and More
This general-purpose wheel is at home on mild steel, welds, cast iron, and masonry surfaces. It is not a diamond cup wheel, but it provides dependable stock removal and a smooth finish on flat work. For best results, keep the wheel at a consistent angle and let the tool do the work—no heavy leaning.
