An impact wrench is called numerous names such as air impact wrench, air gun, torque gun, windy gun, impactor, impact gun, etc.

And, it has a simple function to deliver remarkable torque output and requires to apply minimal or no effort. Such a feat is achieved by storing and converting the electrical energy into rotational energy, which is then outputted on the shaft of the device for optimum torque.

3/8 VS 1/2 Impact wrenches

In this section, we will be thoroughly discussing all the relevant information regarding both a 3/8 and 1/2 impact wrenches.

Sizes

Obviously, the first difference between the two 3/8 and 1/2 impact wrenches are the size. The 3/8 is much smaller than the 1/2 impact wrenches. Also, the 3/8 wrench tends to be lighter than the 1/2 wrench and, hence, allows better maneuvering factor

Functionality

The smaller 3/8 impact wrench is ideal for working with tighter spots, which is attributed to its compact design. So, they can effortlessly work with 10 mm or less bolts and, is a prominent option to when you are dealing with projects that require finer accuracy and precision.

Whereas, the more substantial and common one among the two, the 1/2 impact wrench, could be considered a better option when you require power, precision, and accuracy. The 1/2 wrench fall in the middle of the size chart for an impact wrench and guarantees enhanced precision as well as robust drilling.

Furthermore, the 1/2 wrench promises safer removal of nuts and bolts without the fright of applying too much power.

Power

We have already discussed that a 1/2 impact wrench is a superior option when working with heavy-duty projects. Thus, working on projects that require higher power means that the 1/2 impact wrench should output a higher torque or pressure.

That exactly what the 1/2 impact wrench does! A 1/2 earthquake xt cordless impact wrench can yield from 20 pound-foot to a staggering 150 pound-foot. Such a high power output is more than enough to drill, remove, and complete all sorts of rigorous industrial works.

But the 3/8 impact lacks in power. It outputs a much smaller power compared to its bigger cousin, 10 to 90 pound-foot. Hence, it is a preferable option when working on projects that require precision over power.

Uses

The 3/8 is compact and ideal for precision works. Therefore, DIY’s, woodworks, zip nuts, and other smaller forms of work.

And, the 1/2 impact promises more power. Therefore, it is exceptional with hefty works such as lug nut removals, suspension works, automotive tasks, industrial maintenance, and constructional works. And if you can get the best cordless impact wrench for automotive, that would be amazing.

Design

Durability Of The Bolts

The 3/8 works on bolts which are 10mm in diameter, or less. Bolts are narrower than the bolts for a 1/2 wrench and, so, are fragile. This is why 3/8 is a preferable choice when working on projects that require lesser force and use more papery bolts.

Which One To Pick?

It depends entirely on the type of work you are doing. If you are working on a project that requires superior force and durability, then the 1/2 is a wiser option. And, if you are working on something that is more fragile and requires exceptional precision, then we suggest that you lean towards the 3/8 impactor.

But, in our eyes, the 1/2-inch impact gun is slightly superior. It falls in the middle of the size chart and hence, has both power as well as accuracy. All these factors make it a remarkable device to have in your arsenal.
