Best Cordless Impact Wrenches in 2021

The best cordless impact wrenches are also known are impact  guns, air wrenches, rattle guns, impactors, windy guns, etc.

The socket wrench has a socket at the end that is used to turn a fastener such as nuts and bolts. The torque to fasten or unfasten a nut or a bolt may be delivered by power. Thus an impactor is a power tool designed to deliver a high torque to reduce the exertion for the user. It stores energy within a rotating mass and delivers it via an output shaft. The most common power source is compressed air but hydraulic power and electric power are also used. Battery powered devices have become popular since the mid 2000s.

How does an Impact Wrench function?

The impact wrench functions by storing potential energy in a rotating mass that releases it in small impacts against the output shaft. This puts a lot more force against the nut of bolts you are trying to tighten or loosen and takes the strain off your wrist.

The bit sits still on the nut and turns only when the hammer hits the bit at each turn when it engages with the output shaft.

The output shaft is fitted with a hammer and spring in series. The spring loaded hammer lifts up, spins around to be driven down by the spring and forward by the drill at high speeds.There are slots cut into the hammer that slide onto the output shaft.

Springing the hammer on to the output that transfers the impact and torque to the bit that turns the nut or bolt you are trying to tighten or loosen. The motor generates high amounts of torque  much more than any human can produce. This hammer shaped mass continues to turn thus the operator feels only a tiny impact.
