Understanding the Torque: A Deep Dive into Impact Wrench Mechanics

One last note before we get to rating the top cordless impact wrenches: torque in the form of breakaway torque and fastening torque or impacts per minute (ipm or bpm) are crucial in measuring power and efficiency. While breakaway torque deals with the initial power to break a nut free, fastening torque acts as a better predictor of what the impact wrench will be able to handle in the real world. It’s this combination of power and control that professionals and DIYers alike want in an impact wrench.
