The M4 4-Volt Lithium-Ion Cordless Screwdriver Kit incorporates the latest Milwaukee core technologies in motor, REDLINK Intelligence electronics and REDLITHIUM 2.0 batteries, increasing power and run time while shrinking its size. It features a 21-position clutch with auto shut-off that stops rotation of the bit once the desired torque setting is met.
