The DeWalt DCG408B is a 20V MAX cordless angle grinder with a brushless motor and a 4.5 in. wheel. It holds speed under load, adds overload protection, and carries a kickback brake plus E-CLUTCH, which cuts power if the wheel binds. A paddle switch runs the tool and a clip-on guard converts the Type B guard for cutting. It suits tradespeople and serious DIYers already on DeWalt's 20V battery platform; the bare tool ships without battery or charger, so the value depends on batteries you own.
