Dewalt DCG408B 20V Brushless Angle Grinder 4.5 in

Product Description

The BLACK DECKER/DEWALT DCG408B is a 20-volt MAX brushless cordless angle grinder built for professional grinding and cutting applications. The brushless motor maintains constant speed under load, which is critical when working through metal, masonry, or other tough materials. Overload protection extends tool and motor life during heavy-duty use. The paddle-switch design gives users confident, deliberate control of the tool during operation. This grinder accepts 4.5-inch wheels and ships with two guards: a Type B guard for grinding and a Clip-On Guard that converts the Type B guard for cutting operations. Licensed electricians, ironworkers, pipefitters, and general trade contractors are the primary installers and operators of this tool.

The DCG408B is suited for residential and commercial jobsite use wherever cordless mobility is required. It works on the 20V MAX battery platform, making it compatible with other tools in that system. Typical applications include cutting rebar, grinding welds, preparing metal surfaces, and cutting tile or masonry with appropriate wheels. The paddle switch provides an added layer of safety by requiring deliberate hand engagement before the wheel spins.
