Ultra-compact impact wrench for automotive repair, maintenance work, equipment servicing and confined-space fastening applications
The Milwaukee M12FSCIWF38-0 is a sub-compact 12V impact wrench developed for professional technicians who require high fastening performance in restricted working environments. Powered by a POWERSTATE brushless motor, the tool delivers up to 271 Nm of fastening torque and 305 Nm of nut-busting torque while maintaining an overall length of just 114 mm. This compact architecture allows access to fasteners located within engine compartments, suspension assemblies, HVAC installations, industrial equipment and service areas where larger impact wrenches cannot operate efficiently.
Weighing only 0.91 kg when equipped with an M12 HB2.5 battery, the impact wrench is designed to minimise user fatigue during prolonged overhead or repetitive fastening work. The 4-Mode DRIVE CONTROL system allows users to select different speed and torque settings according to the application. Auto Shut-Off mode limits fastening torque to 14 Nm during hand-tight applications to reduce overtightening, while Bolt Removal Control delivers full reverse torque before automatically reducing speed once the fastener breaks free. Tri-LED lighting provides shadow-free illumination of the working area, improving visibility in confined spaces and low-light environments.
