The Chicago Pneumatic 1/2" impact wrench, No. CP7739, features patented side-to-side (S2S Technology) forward/reverse functionality located directly above the trigger. Weighing only 2.78 lbs. and 6.4" in length, the CP7739 delivers up to 450 ft./lbs. of true torque. The three position regulator in forward provides control and helps to prevent over-tightening, while full power remains constant in reverse to ensure users have maximum power to remove fasteners without changing the setting in the forward position.
