18V Li-ion 3/8” Impact Wrench, No. ARI20120B

The ACDelco 18V Li-ion 3/8” Impact Wrench, No. ARI20120B, offers a digital clutch with Electronic Torque Clutch (ETC) that delivers 170 ft/lbs of maximum breakaway torque, 125 ft/lbs of maximum reverse torque and 80 ft/lbs of forward tightening torque. The ARI20120B weighs 3.6 lbs and fits in tight space and is designed for solving under-/over-torquing issues. According to the company, with the ETC, the need for a torque stick is eliminated. With five preset torque settings and an additional maximum setting, dialing-in the pre-programmed ft/lbs now easily controls torque. Once the desired torque is reached the digital clutch stops the anvil. No calibration is required even if the battery is low or aged; the tool’s electronics compensate to achieve the chosen torque.
