Our take on the DEWALT 20V MAX 1/2 in. Brushless Hammer Drill/Driver DCD999B

The DCD999B is DeWalt's top 20V MAX hammer drill, sold as a bare tool. Its brushless motor and three speed ranges (up to 2,000 RPM) put it above the older DCD996 in torque and speed control, and the 1/2 in. keyless chuck takes standard bits. It suits contractors and serious DIYers who already own 20V MAX batteries and want one drill for wood, metal, masonry and driving screws. Reviewers rate its power and build highly; the main complaints are its weight and that no battery or charger is included.
