The Bosch PS41 12V Max Impact Driver is an easy-to-use tool, with a 5.4 In. head length, yet it delivers a max torque of 930 In.-Lbs. It weighs just only 1.8 Lbs., but it can produce a no-load ipm 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 12V Max 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.
