No one appreciates a good air impact wrench like a victim of stubborn nuts would! While you may not immediately recognize the value of such handy tool, it becomes apparent once you come to deal with a stuck rusty fastener that won’t budge, particularly when you are tired or pressed for time.

These efficient, powerful and versatile power tools have made life much easier for anyone, from construction workers, mechanics and factory workers to DIY enthusiast. To extend the range of applications, air impact wrenches come in different sizes, power levels, and can be used with different sockets and accessories.

In this article from Ronix, you’ll learn the ins and outs of choosing the best air impact wrench for different needs and expectations and add the best option to your shopping cart! 

But let’s start with the basics:

How Does an Air Impact Wrench Work?

A pneumatic impact wrench (gun) works by converting the energy of compressed air to rapid and high-torque impacts, enough for tightening and loosening any nut and bolt.

Air Impact Wrench: Advantages and Applications

Unlike its battery-operated and electric counterparts, a pneumatic impact wrench does not depend on batteries or a motor to work and is therefore lighter in weight.

Moreover, it has fewer moving parts which make it less vulnerable to corrosion and is capable of delivering high levels of torque which make it well suited for demanding tasks like auto repair and maintenance, repairing heavy machinery, product assembly in factories.

Having said that, relying on the right socket and accessories you can also use your pneumatic wrench for lighter tasks such as installing shelves, repairing your bicycle, changing a car’s tires or assembling furniture at home.

The tool market is filled with air impact wrenches that vary in torque output, BPM and drive size. With a detailed buying guide, you can avoid confusion and narrow down your options based on your needs and the intended use.

The Best Air Impact Wrench: A Buying Guide

When looking for the best air impact wrench, always check the specifications for the following information:

  • Max Torque
  • Weight
  • Working Pressure
  • Impact Mechanism
  • Driver Size

Max Torque

Torque measures the tightening force an impact wrench applies when turning a fastener. While a not-tight-enough bolt can come loose and lead to safety risks or equipment malfunctions, overtightening it is also problematic cause it can damage the fastener or the surrounding components. Therefore, it’s important to choose a tool that can apply the appropriate amount of torque for your specific application.

For light-duty tasks like changing tires, a tool with 400Nm of torque may be sufficient. For heavy-duty industrial applications, you may need a tool with up to 1600Nm of torque or more.

Weight

As impact wrenches are handy tools for everyday use, you better go for a model that is light in weight and ergonomic in design. That way you can guarantee comfortable and fatigue-free operation during extended use.

However, more torque and power often translate into more weight, and that is inevitable!

Working pressure

Working pressure determines the air pressure your pneumatic machine needs to operate at its best.

The higher the working pressure of a wrench is, the more torque it will generate and the faster it can fasten bolts and nuts. However, higher working pressures are not always good because they result in more wear and tear and less durability.

Most top air impact wrenches work with 90 pounds per square inch (psi).

Impact mechanism

As mentioned above, impact wrenches can loosen some of the most stubborn fasteners by applying rapid impulses of torque.

Based on this so-called impact mechanism, there are two main types of pneumatic wrenches: hammer and anvil models and pin clutch ones.

Compared to hammer and anvil wrenches, pin clutch ones are less noisy, more compact and durable but produce lower levels of torque.

Driver size

The driver size of an air wrench is a crucial factor in determining its suitability for different fastening tasks.

The most commonly available driver sizes are 1/2, 1/4, and 3/8 inches. Larger drivers are designed for heavy-duty tasks, while smaller ones are better suited for turning smaller fasteners or bolts in hard-to-reach areas. Therefore, it’s important to choose a driver size that best fits your needs based on the type of tasks you’ll be performing.

Let’s dive deeper:
