Milwaukee Fuel Impact Wrench, 3/8", Compact 12V Wrench for Automotive Work

The tool delivers up to 113 Nm of torque, making it suitable for automotive fasteners, bike repairs, appliance assembly, and light construction tasks where access is limited and a full-size impact wrench isn’t practical.

‘FUEL’ indicates Milwaukee’s advanced, high-efficiency motor design. The brushless motor provides better efficiency, longer life, and more consistent performance under load, helping you complete tasks with less heat buildup and faster cycles.

The bare tool includes the impact wrench itself with no battery or charger. If you’re comparing to a kit, a bundle would include one or more Milwaukee M12 batteries and a charger, giving you immediate power out of the box.

Yes. The M12FIW38-0 is compatible with all Milwaukee M12 lithium-ion batteries, so you can choose the capacity that fits your workflow and runtime needs.

It features a 3/8" square drive with a friction ring for secure socket retention, helping sockets stay in place during operation.

Yes. Its sub-compact 12V design and ergonomic grip are specifically intended for working in tight spaces where larger tools can’t fit, while still delivering adequate torque for common fasteners.

Insert a charged M12 battery, attach the desired 3/8" socket to the drive with the friction ring engaged, and use the trigger to control operation. For best results in tight spots, position yourself so you can apply steady, controlled force and maintain visibility with the tool’s LED light if your work area is dim.

Wear appropriate eye and hand protection, ensure the socket is properly seated in the drive, keep fingers away from moving parts, and avoid over-torquing fasteners. Use a charged battery and work in a stable stance to maintain control in confined spaces.

Choose the bare tool if you already have M12 batteries and chargers or if you’re building a modular setup. Opt for a kit if you need a ready-to-use solution with batteries and a charger, giving you immediate power without sourcing components separately.

Keep the tool clean and dry, store with a charged battery, and avoid exposing it to harsh moisture or dust. Since it’s brushless and designed for durability, routine care is mainly about keeping the drive area free of debris and using quality Milwaukee M12 batteries to maintain consistent performance.
