An air impact wrench is an impact wrench power tool made to deliver maximum torque with minimum exertion by the part user and by storing kinetic energy in a rotary mechanism, then delivering it quickly to the attachment point. It was originally invented by Robert H. Pott in Evansville, Indiana. He received the patent in October 1977 and the first air impact wrench was made in the United States in eight months.
The working of this wrench is very simple. First of all, it is held vertically in the wrench arm and is held vertical by three wheels mounted on a shaft, which rotates counter-clockwise, reducing friction. Next, the part that needs to be accessed is gripped by a trigger, and air is compressed by an inboard motor that rotates counter-clockwise, increasing the pressure of the gas, and allowing the wrench head to enter the hole. Lastly, a plunger attached to a valve at the top of the air impact wrench's intake manifold, releases the compressed gas to increase the pressure, allowing the head to enter. This cycle continues indefinitely and is similar to a bicycle pump.
There are two main types of air impact wrenches available in the market today. One is powered by a corded battery and the other is an electric one. It has been observed that the cordless tool is more convenient than the other as it is more reliable and long lasting. Moreover, when the corded tool runs out of batteries, it requires a converter box to recharge its air supply.
Compared to the corded wrenches, the electric air impact wrenches come with a host of advantages, which include portability, ease of use, versatility, and portability, all of which are vital for professional plumbers and contractors. The electric version is particularly popular among construction workers who often travel and need to bring heavy-duty wrenches along. The electric version can even be used to repair torches, and light bulbs; it can even be used as a pneumatic drill (through a portability port). Some of the best electric air impact wrenches are the Littmann Electric Joints Harness Adapter and the Husqvarna 250ZSA.
Air impact wrenches also have a host of portability features. These are usually found on pliers with an adapter that allows them to be carried around as compactly as a small handbag. Often, these are used in cars, to remove car seats or other objects that are stuck between the console and the vehicle. They can even be used as screwdrivers to remove nuts from bolts, and sometimes they even have scissors that can be inserted into nylock nuts and removed. This feature is almost always found on a corded version, as cordless models are usually limited to the amount of pressure they can exert before their batteries run out. They can however be used with almost any power source, including cigarette lighter cords and car cigarette lighter ports.
There are many more features that air impact wrenches can have. This means that every homeowner or professional needs to be made aware of the different features that are available so that they can get the best air impact wrench suited for the job that needs to be done. The best air impact wrench should not only be adjustable in length but should also be able to handle both soft and hard rubber, nails, bolts, and nuts. If the best air impact wrench does not have all of these features, it is probably not worthwhile buying one. You will not get the best results from your purchase if you end up with a tool that cannot handle the task at hand.
