The M12 Fuel Stubby 3/8" Impact Wrench, No. 2562-20, from Milwaukee Tool, delivers up to 3,000 rpm with 550 lbs.-ft. of nut-busting torque. The wrench only weighs 2.2 lbs., reducing user fatigue and increasing access to cramped spaces. It is equipped with tri-LED work lights and 4-mode Drive Control for increased precision. It also features Auto Shut-off, which applies no more than 15 lbs.-ft. of torque to prevent overtightening in hand-tight applications. When used it reverse, it engages bolt removal mode and slows down the rpm once the bolt is free to prevent it from being ejected or dropped. Changing modes only requires shifting the forward-reverse shuttle into neutral and double-tapping the trigger.
