Bigger is not always better in the tool world, and while many of the jobs that you will carry out on a day to day basis are made easier by more power, some are made more difficult.  When you need to be able to get your hands on a tool that deals will with precision rather than relying on brute force, you will find that a 3/8 impact wrench is the perfect partner.

Although you probably associate an air impact wrench with the kind of relentless power required to remove a wheel or tighten up a set of bolts on an engine block to a very high level, they also have a wide range of other uses, and many of these rely on the ability of the impact wrench to perform under many different circumstances.  One of the big advantages of a 3/8” impact wrench is in its ability to get into smaller spaces than the larger systems.  This coupled with the design of the tool, which holds the nut in place in the grip meaning that when you need to get into a smaller area, you will be able to do so without any problems.

There are numerous different occasions where smaller size is a useful feature.  Imagine trying to force a larger tool into the confined space between an engine and the chassis of a car, or into a tiny space under an industrial machine in a factory.  Sometimes it seems as thought there are as many small areas as there are jobs that need doing, and having tool that is too big to use with care in a confined space makes the job harder to do and means that mistakes are more likely.

There are both electric powered and air powered 3/8 impact wrenches available, and the exact model that you choose will depend on your needs.  An electric wrench does not require connection to a compressed air supply for power, and can simply be plugged into the mains electricity supply.  This means that it is a little more convenient in use, although you do tend to find a little bit less power and torque than you would get from a compressed air model, and obviously the devices a re a little heavier thanks to their electric motors.
