Our take on the DeWalt DCG402B ATOMIC 20V MAX 4-1/2 in. Angle Grinder W/ DCB205-2C 5.0Ah Starter Kit

This bundle pairs the DeWalt ATOMIC 20V MAX 4-1/2 in. angle grinder with a 20V MAX 5.0Ah battery starter kit, so the tool runs out of the box. The grinder is built for tight spaces: a slim body with a smaller grip diameter, up to 760 MWO, and an electronic brake that stops the wheel within 1.25 seconds of releasing the trigger. The 5.0Ah XR pack carries roughly 60% more capacity than DeWalt's standard 20V MAX pack and has a 3-LED fuel gauge. It suits tradespeople and serious DIYers who cut and grind in cramped spots and want one-battery cordless convenience; corded grinders still deliver more sustained power for heavy continuous work.
