Cordless screwdrivers are nothing new, but this model from DeWalt puts a heavy-duty twist on the idea, and professionals are sure to appreciate it. DeWalt's 7.2-volt has the most powerful battery pack of any cordless screwdriver on the market, without sacrificing compact design. This screwdriver gets into all the tight spots cordless drills can't, and unlike other cordless screwdrivers, it won't leave you wishing for more power once there. Its 80 inch-pounds of torque is beyond even the toughest competing model, and with 16 clutch settings, it's easy to avoid stripping out screws. We also like this tool's quick-change keyless chuck and the extra maneuverability provided by the two-position handle. This is a generous kit, including the driver, a charger, two batteries, two bits, and a tough case. It may not be a revolution, but it does seem to be the first serious cordless screwdriver designed with professionals in mind.
