It offers different torque levels for tightening and loosening bolts, with the more powerful model delivering 922 ft - lbs of tightening torque and 958.8 ft - lbs of loosening torque, and the other 258.1 ft - lbs of tightening and 280 ft - lbs of loosening torque. High - capacity battery: Comes with either two 4000mAh batteries (in one model) or one 4000mAh battery (in the other model), ensuring long - lasting power for extended high - intensity tasks and minimizing recharging interruptions. Dual - mode torque: Features two torque modes, tightening for high - strength bolt fastening and loosening for removing rusted or over - tightened fasteners, with specific torque limits for each mode depending on the model. Three - speed settings: Offers three adjustable speeds. One model has speeds of 1300RPM for precise control, 1500RPM for general tasks, and 1800RPM for quick, high - intensity jobs; the other has 1500RPM for precise control, 2000RPM for general tasks, and 2600RPM for high - intensity jobs. Multiple socket sizes: Each impact wrench set includes 5 socket sizes. One set has sizes like 1.3 - inch for tight spaces and others for different depths and torque needs, while the other set has socket sizes ranging from 0.7 to 0.83 inch to fit various screws and nuts.
