The Flex IW 3/4 18.0-EC C Cordless Impact Wrench is equipped with a brushless motor and its Electronic Management System (EMS) helps to protect the machine, extend the service life and increase efficiency. The robust gearbox housing is made of die-cast aluminium. The Impact Wrench's powerful impact mechanism ensures maximum performance and enables stuck or rusted screw connections to be loosened, even in extreme applications. A damping element separates the hand grip from the motor, bringing a significant reduction in vibration transmission. The accelerator trigger switch allows variable speed and has a locking function that helps to prevent fatigue. There is also a quick-acting electronic brake. The wrench has an ergonomically designed, non-slip, soft grip handle and an integrated LED lamp with persistence function. There is also an LED battery capacity display.
