People who have tried the new M12 Fuel drivers say they pack a lot of power for their size. According to Milwaukee, the tools’ brushless motors are more efficient than standard motors, and their “Redlithium” batteries provide up to four times more runtime and 20% more power than standard li-ion batteries. The line consists of a screwdriver, a drill/driver, a hammer drill/driver, and three impact drivers. The 1/4-inch Hex Impact Driver Kit shown costs $170.
