Key features include a 3/8\" square drive, compatibility with Milwaukee’s M12 battery platform, a brushless FUEL motor for efficiency and durability, a compact and lightweight body for maneuverability, and a variable-speed trigger for controlled fastening and loosening.

Drive size: 3/8\" (9.5 mm) square drive. Platform: M12. Voltage: 12V. Motor: Brushless (FUEL) for efficiency and longer tool life. Type: Cordless impact wrench. Tool only (battery and charger sold separately). Intended for forward and reverse operation with a variable-speed trigger.

Ideal for automotive work in tight spaces, bicycle or scooter maintenance, light fabrication and assembly, furniture or cabinet assembly, and any task that requires loosening or driving small to mid-size fasteners in confined areas.

1) Insert an M12 battery (not included) and ensure the charger is ready if you’re setting up for use. 2) Attach a compatible 3/8\" drive socket or accessory to the tool’s drive. 3) Select forward or reverse and gently squeeze the trigger to begin; apply steady pressure and adjust speed with the trigger. 4) When finished, release the trigger and disconnect the battery before changing sockets or performing maintenance.

Wear eye protection and secure your workpiece with clamps. Keep loose clothing, hair, and jewelry away from the tool’s moving parts. Inspect sockets and accessories for wear before use. Use the correct 3/8\" drive sockets to prevent slippage, and avoid using the tool for tasks beyond its intended 12V, lightweight fastening range.
