Perhaps the tool that most people immediately associate with air power is the impact wrench.  In its many different forms, the impact wrench has been the cornerstone of so many different industrial, construction and mechanical jobs, that there is probably no tool that has been used to such an extent.  In order to satisfy the individual needs of each of the jobs it is required for, this tool comes in a wide variety of shapes and sizes from high powered designs intended to be used in heavy duty tasks on trucks and construction projects through to ½” impact wrench, which is more accurate in use, and ideal for smaller tasks thanks to its convenient size and user friendly nature.

Unlike much larger tools such as the full size one inch models that are limited to the really big jobs, the ½” impact wrench is a highly flexible tool that can be used for everything from basic engine work through to construction.  A 1/2” impact wrench combines a lightweight but durable design with plenty of power, and will always come in handy when you are working.

Most of the well known tool manufacturers produce 1/2” impact wrenches, and they are available in both air and electric powered versions.  The preferred model of the modern mechanic is of course the air powered ½” impact wrench, due to its lighter weight, greater power, and better torque, although for home use where a compressed air supply is not available, then an electrical ½” impact wrench will serve perfectly well.

Unlike larger models, ½” impact wrenches are designed around their ability to get into smaller gaps, and th
