The Mac Tools 3/4" drive impact wrench, No. AWP075, provides muscle, durability and efficiency needed in high-torque applications. The 8.4-lb impact wrench offers the highest power-to-weight ratio in the marketplace, according to the company, thanks to its low weight and 1,560 ft/lbs breakaway torque. This tool features titanium components in the clutch housing, a reverse lever and exhaust deflector, and an innovative motor construction that requires fewer parts. A side-fed air motor provides an unobstructed path for airflow, which results in more power during application. A feathered throttle offers maximum operator control over the power output.
