Product Overview
Bridging the gap between compact maneuverability and heavy-duty power, this Mid-Size 1/2″ Brushless Impact Wrench is engineered for professional automotive, industrial, and steel structure applications. Driven by a 600W high-efficiency brushless motor, it delivers 900N.m fastening torque and a massive 1050N.m max breakaway torque. The intelligent 3-speed electronic control precisely matches RPM (1800/2600/3200) and BPM (1900/2500/2700) to the task. With a 1/2″ square drive and 14-36mm socket compatibility, it effortlessly handles M12~M24 standard bolts and M10~M18 high-strength bolts. Ideal for global distributors, fleet maintenance shops, and B2B buyers seeking reliable OEM/ODM cordless fastening tools.
