Chicago Pneumatic CP7755-1/2 Inch Air Impact Wrench with Short Anvil, Air Flex Mini, Pistol Handle, Max Torque Reverse Output 959 ft. lbf / 1300 Nm, 7700 RPM, Twin Hammer

First week as a full time tech: - Easily loosened rear control arm nuts using a swivel, without even holding a bolt. No excessive vibration while holding a tool. - Quickly removes lug nuts from heavy pickups. Loosens axle nuts. -Now to tighten it, attention is needed. Had to test the torque percentage knob accuracy before tightening bolts and lug nuts on smaller vehicles . It all depends on how long the nut was being hammered on. Used a torque wrench to check if the lug nut torque was met. At 35 percent and four second hold time with 90 psi air supply it was about 100 ft/lbs. At 40 percent and two second hold time it was 97 ft/lbs. The math in the booklet is different, but I'm not disappointed, it all depends on air supply and how quickly the job is being done. It's the tool I've been waiting to show up on the market, with this type of variable torque setting.
