There are places that you cannot get to with a cord attached to the wrench, and electric wrenches usually run on rechargeable battery packs. This makes for a great tool that has the application for changing a flat tire, or doing construction around the house, and the cost is significantly less than the air compression model.
You should know that the most important power source is the compressed air which provides a low cost design. The power to weight ratio is also quite good. Almost on all the cases the simple vain motor is used. As far as the lubrication system is concerned, the most common one is the oiled air. Some of the others are the special oil passages. It is routed to the parts that need it. Some of the other parts that need it are the gear reduction system.
An impact wrench, when in operation, works based on acceleration of the motor, storage of energy which when connected to the output shaft can create a high-torque impact. The mechanism is designed in such a way that it allows the hammer inside to spin freely after delivering the impact. The choice of such wrench largely depends upon the application and usage. Compressed air is most common power source of these wrenches these days. There are some models that work based on hydraulics. However, keeping in mind the light duty work, there are many types of cordless or electric wrenches as well.
Some of the most reliable brands out there are Milwaukee, which offer some of the strongest air impact wrenches out in the market, and Ingersoll-Rand, which provide not only some of the sturdiest wrenches, but also offer most power tools that are both efficient and reliable.
Buying an air impact wrench is an important addition to any do-it-yourselfer's home toolkit, but there are also a couple things that you need to remember before you go out and buy one. These are the size of your air compressor, what size drive you need, and not under-estimating how much power you'll need.
