High-performance compact impact wrench for automotive repair, maintenance engineering, mechanical assembly and confined-space fastening applications
The Milwaukee M12FCIWF38G3-0 is a third-generation M12 FUEL compact impact wrench designed for professional users who require high fastening performance from an ultra-compact cordless platform. Powered by a POWERSTATE brushless motor, the tool delivers up to 542 Nm of fastening torque and an impressive 745 Nm of nut-busting torque, enabling it to tackle demanding automotive, industrial maintenance and mechanical fastening applications that would traditionally require larger 18V tools. Despite its output, the tool maintains a compact overall length of only 122 mm, allowing access to restricted work areas where larger impact wrenches cannot operate effectively.
Weighing only 1.0 kg without battery, the M12FCIWF38G3-0 is engineered to reduce user fatigue during repetitive fastening tasks and prolonged overhead work. The 4-Mode DRIVE CONTROL system allows users to select the most appropriate speed and torque settings for different applications, while trigger-based mode selection enables quick one-handed adjustments. Tri-LED lighting provides shadow-free illumination around the fastener, improving visibility in engine bays, machinery compartments and poorly lit work environments. Milwaukee’s REDLINK PLUS electronics continuously optimise performance and system protection when used with M12 REDLITHIUM battery packs.
