Buying Guide

How to Choose the Best Pneumatic Impact Wrench

Some of the points you definitely need to consider before buying a pneumatic impact wrench are as follows.

The tool’s weight

It is important to consider the weight of your wrench. If it’s too heavy to hold, it will be a total waste of your money. It’s better to get the one with lightweight so you can operate it easily.

The quality of the handle

The handle should have enough space to easily and conveniently hold your tool, so it does not hinder your performance.

A perfect torque

A perfect spiking torque is a must, or an impact wrench would be of no use. The torque should efficiently clamp/unclamp the objects.

Reservoir’s Volume

This determines the time of use of the tool. The wrench does not repressurize itself; therefore, it needs a reservoir volume of at least 50 liters.

Shock sockets

Always go for shock sockets as the nonshock sockets would break instantly.

Drive size

You need to consider the drive size, which totally depends on your work. A 1 to 2-inch drive size is enough for larger nuts, but they also may vary up to 3 inches. It all depends on what type of task you’re going to do.


How do pneumatic impact wrenches work?
