A pneumatic impact wrench works on compressed air. The tool is connected to the air compressor with the help of air hoses. The length of the air hose depends upon the user and how far they are going to place the air compressor. Once the pneumatic impact wrench is connected to the air compressor with the right hose, the air pressure is turned on the air compressor.


Once the compressor is turned on, the compressed air reaches the motor of the tool and powers it. When the motor gets power, it forwards that force to the head of the impact wrench. So, the head starts moving and the anvil starts rotating rapidly in the chosen direction. A pneumatic impact wrench applies more force on the stubborn nuts than a cordless impact wrench or even a corded impact wrench. This makes it ideal for professional-level users.

It is best if you use both hands while holding the tool.


Moreover, never use a high torque tool such as a pneumatic impact wrench without wearing the proper safety gear first. Always wear eye protective goggles, and ear muffs for noise cancellation.
