Some top-rated cordless drill drivers are the Makita LXFD03, DeWalt DCD790D2 and Hitachi DS18DSAL, according to Top Ten Reviews. Milwaukee, Rockwell, Porter-Cable and Bosch manufacture good drills as well.
The construction of the well-reviewed Makita drill driver protects it from dust and water while boasting 750 inch-pounds of torque. It also has several speed settings at 400 RPMs per minute at the slowest rate and up to 2,000 RPMs at the fastest. The drill's 18-volt lithium-ion battery lasts for days with only a 30-minute recharge time.
The DeWalt DCD790D2, which also received favorable reviews, weighs in at a lighter 3 1/2 pounds. Although it doesn't have a torque rating, it contains a 20-volt lithium-ion battery that recharges after 35 minutes and lasts for at least a day.
The Hitachi DS18DSAL only has a torque rating of 460 inch-pounds, almost half the power of the Makita, it also can only drill up to a 1 3/4-inch hole in wood, a far cry from the 3-inch hole the Makita drill provides or the 2-inch hole by the DeWalt.
Next to the Makita, the Rockwell RK2852K2 has the next-highest torque rating at 725 inch-pounds. It can also drill 3-inch holes in wood and a 1/2-inch hole in metal. It has more clutch settings than the current front runner; however, it takes almost a full hour to charge completely.
