Cordless Impact Wrench - Not the Same Tool as Your Cordless Drill

The cordless impact wrench has rapidly in popularity among professional mechanics and the hobby mechanic as well. As you can imagine, "I already have a cordless drill, I use for impact applications, why do I need a cordless impact wrench, too?". I thought the same thing. The first difference is on the inside. A cordless drill creates continuous in-line torque. A cordless impact driver uses an internal spring-loaded pulsating cam to create rotational torque. This createsthe "impact" force that replaces a mother. It is the equivalent to a wrench with a hammer to beat a rusty nut only be solved much faster. Unlike a cordless drill - which creates continuous in-line torque, a cordless impact driver uses an internal spring-loaded pulsating cam and gear, a rotating torque, or the "effects to create" to force.

Another big difference is the lack of reactionary torque. Reactionary torque is what you experience with your cordless drill. You have to use bruteForce to keep the holes from spinning the opposite direction in his hand. With a cordless impact wrench, that torque is not directed at the mother's arm. You can keep this tool in one hand and let the cordless impact wrench to do all the work. No more pushing down on the tool and that screw drive. These instruments are also smaller and lighter than a cordless drill. For example, a DeWalt cordless impact wrench is about 35% of the size of comparable cordless drill. This property makesdifficult to get them perfect for all those overhead projects and up to, spaces.

The next time your starting deck, that big project in the backyard, let a cordless drill that into the box and pack your cordless impact wrenches. The arm will thank you at the end of the day.
