Anvil Air impact Wrench

About Impact wrenches:
There are many kinds of pneumatic impact wrenches, most of them are distinguished by the length of the blades mounted on the internal rotor.

The longer the blade, the longer the rotor, the larger the cylinder, the more air is consumed, the higher the quality of the air compressor, and the weight of the pneumatic wrench will increase. It is often said that the torque of a pneumatic wrench is proportional to the weight.
