Generation 2 THOR designed to be the highest performing 1/2" impact wrench on the market. Maintains a short length like the original Astro THOR impact wrench but with several improvements. Rated 1,020 ft-lbs traditional Max Torque (compare to 1650 nut-busting) thanks to a larger motor and greatly increased air passageways in the handle and trigger feeding it. New linear trigger allows for more throttle adjustment and feathering compared to previous 2-stage trigger. New slightly widened THOR hammer texture handle with top hump flattened for a more comfortable grip, and roll-pin hole removed for less air leak opportunities. Includes power adjustment wheel and improved FWD/REV rocking lever. For use with 3/8" or 1/4" NPT HI-FLO fittings (adapter for 1/4" included), 6.8 CFM continuous use.
