14.4v Cordless Impact Wrenches

Check out the newest technology – Lithium Ion cordless Impact Wrenches

A cordless impact wrench employs an internal spring-loaded pulsating cam to create rotational torque. This creates the "impact" force that loosens a nut. It is the equivalent to banging a wrench with a hammer to loosen a rusty nut only a lot faster. Unlike a cordless drill - which creates continuous in-line torque, a cordless impact driver uses an internal spring-loaded pulsating cam and gear mechanism to create rotational torque or the "impact" force.

Another big difference is the lack of reactionary torque. Reactionary torque is what you experience with your cordless drill. You have to use brute force to keep your drill from spinning the opposite direction in your hand. With a cordless impact wrench that torque is directed to the nut not your arm. You can easily hold this tool in one hand and let the cordless impact do all the work.
