The Jonnesway 1138L Ultra-Light 1" drive impact wrench weighs just over 18 lbs and delivers over 2,300 lbs of reverse torque to remove the most stubborn nuts. The 1138L is designed and engineered to deliver maximum torque in a compact and easy-to-hold impact wrench. Composite materials help to protect the wrench when dropped, and the "soft feel" of these materials makes the wrench very user-friendly. The special "twin hammer mechanism" is designed to deliver maximum power while extending the life of the tool.
