This cordless 4-volt Screwdriver incorporates the latest Milwaukee core technologies in motor, Red Link Intelligence electronics and Red lithium 2.0 batteries, increasing the tool’s power and run-time, while shrinking its size. It has a 21 position clutch with auto shut-off that stops rotation of the bit once the desired torque setting is met. The quick-change chuck allows for one-handed bit changes, and a snug bit grip prevents dropped screws when the screwdriver is inverted. Drill mode easily drills pilot holes or removes damaged screws.
