Only one lithium-ion cell powers this tiny 1.1-pound screw gun, optimizing its weight, size, and maneuverability. The 4-volt tool works in pistol- or stick-drive positions and the 21-position clutch switches between 200 and 600 RPM. Though it's meant for screws, the driver can also drill small pilot holes.
