The Bosch impact driver is the most compact driver in its class, with a 5.4 In. head length. Yet it delivers a max torque of 930 In.-lbs., thanks to Bosch's hammer-and-anvil system. It weighs just over 2 pounds, but it can produce a no-load BPM of 0-3,100 and a max 2.600 RPM. The driver was designed with a spring-loaded impact mechanism that reduces user fatigue. This makes this driver excellent for overhead installations and tasks where room is very tight. It also has an impressive runtime provided by the Lightweight power system. This driver includes a three-light LED Light Ring, a battery gauge indicator and a 1/4 In. hex drive with quick release.
