Best Air Impact Wrench Buying Guide

a pneumatic impact wrenchWe have researched and tested dozens of wrenches and enlisted the best ones among them. You can readily pick the one that fulfills your requirements. You don’t have to worry about the quality and performance of the unit. We did solid research and our list devoids underperforming products.

Yet, if you want to learn more insights about the selection process, you are welcome! Some factors determine whether a pneumatic impact wrench is perfect for you. Below are some important factors that help pick the right wrench. Read and the guidelines to build your concept.

Your Job Level

We all know that we should use the right tool for the right job, right? So, the first thing that comes to play in determining the right wrench is your job level. The wrench can produce the utmost result once it fits with your needs.

Here your job level means the application of the wrench. If you need to use the unit for heavy-duty and professional tasks, you should buy one that has the most forward and reverse torque capability. Again, for the medium level work like maintaining your vehicles and home use purposes, you need to buy the medium ranged wrench.

Durability and Material

Whether you are a homeowner or a professional mechanic, you should look for the tools that offer maximum durability. An impact driver is no exception here. The durability of the wrench saves your pocket and provides extra freedom.

Furthermore, the durability of any product gets from the metal with which it is created. So, you need to look for the metal of the wrench. Composite material and industrial plastic provide the lightweight feature along with increasing the lifespan. Moreover, the most advanced construction of the wrench is the Kevlar Housing body. So, it would be better if you ensure that your wrench’s construction belongs to these categories.

The Torque of the Wrench

The power of a wrench is determined by the torque it produces. The torque can be of two types i.e. forward and reverse torque. In more than 80% of the cases, we use the wrench for loosening purposes. So, we need to give more focus on the forward torque generating capacity of any wrench.

It would be great if we get a wrench that has respectable forward and reverse torque. The reverse torque helps us tightening the nuts/bolts/screws. But, if the wrench does not offer the torque adjusting facility during the load, its reverse torque can make more harm than good. So, our main focus should be on “forward” torque.

The tougher your job, the more torque you need. For the toughest job, you need to look for a wrench that generates 900 foot-pounds and beyond. For medium level jobs, anything above 500 foot-pounds torque is more than enough.  If a wrench offers handsome reverse torque with torque adjustment facility, then it is excellent! 

Size of the Drive

driver size of an air impact wrench

The drive size of the wrench determines its capacity for handling nuts/bolts. The most used and hugely popular drive size of the wrench is 1/2 inch. The drive size could be 1/4 inch, 3/8 inch, 1/2 inch, and so on. We have taken all the wrenches on our list that have a 1/2 inch drive size. This 1/2 inch drive size can handle up to 90 % of the nuts, bolts, and fasteners. Furthermore, the 1/2 inch drive size is the perfect match for almost every vehicle including most of the UVs and RVs.

 If you think you are not looking for the 1/2 inch driver, do not buy anything from this list.  

Weight of the Wrench

Another important factor of the wrench is its weight. Generally, most of the users like a lightweight wrench since it offers less stress on the hands. On the other hand, the weight of the wrench conforms with power and strongness. The best quality wrench always ensures a sound balance between weight and power.

A heavy-weight comes with both the merits and demerits. The heavyweight feature enhances its power and durability but makes the user fatigued. On the other hand, the lightweight wrench reduces stress on the user end but lacks durability. The matter of hope is that the great brand always keeps those things in mind. So, they try their best to give the utmost output maintaining durability and performance.

Our list comprises the top-notch impact wrenches. So, don’t worry about the weight and performance balance if you buy any one of them.

Rotation/Speed of the Wrench

The workforce of an impact driver is determined by the rotational speed it makes. So it is natural that you need more rotational speed to get more powerful torque. Typically, a heavy-duty wrench has a rotational speed from 7500 RPM to 9000 RPM. Anything within the range will give you the utmost power and performance. It will be wiser if you match your needs with the speed of the wrench.

Adjustment Facility

The adjustment facility of the wrench offers the option to regulate the torque level. Changing the mode of the torque is easy and common for almost every wrench. The torque-mode change is done by the flip lever or something like that. But, you need to look for the torque level regulation system.

By torque regulation/adjustment facility we are referring to the system of the wrench that controls the torque level during the job. We need more torque during tougher jobs and less torque during easier tasks. So, in those cases, the torque regulator provides our expected torque. As a result, we get the optimum level of torque and can save our nuts/bolts/fasteners from damaging.

Typically, those wrenches have this system allow 2 to 3 modes of torque regulation. So, if you buy one that has this system, you will get the option to match the torque level with your jobs.

Environment-Friendliness

For the past few decades, noise pollution has been damaging public health severely. So, you need to be careful about the noise created by power tools like an impact wrench. If possible, buy the pneumatic wrench that produces less noise. We should keep our family and neighbors safe from sound pollution, shouldn’t we? But, if you buy the wrench for commercial purposes, then give preference to your business opportunity.

Why Should You Pick An Air Impact Wrench?

removing lug nuts from tires using impact wrench

There is nothing precious than time itself. So, the smart approaches that save time and energy are getting more and more attention. The pneumatic wrench can save both time and hard work by providing its stunning service. An impact driver can do the same jobs in 4 to 5 times lesser than your manual/analog approach.

If you invest your valuable time in loosening/tightening the nuts, bolts, fasteners, and so on manually, you won’t be able to do another important task. We know, the time that we pass never comes back. Furthermore, the old and stubborn lug nuts/bolts need extra force to be removed. Sometimes, it becomes impossible to remove them without the help of impact guns.

Generally, air gun can be of air compressed, electric, and hydraulic. You should pick the air impact gun for several reasons. It is the most common and popular in its class. There are some other reasons to have an air-driven wrench. Such as:

  • The air impact gun is the most powerful so far
  • It lasts longer than any other impact wrenches
  • It is way cheaper than the electric/hydraulic wrenches
  • The unit can handle a lot of tasks and tackles the toughest jobs
  • If you are a mechanic or owns a business, the pneumatic wrench should be your “go-to” tool

How Does A Pneumatic Impact Wrench Work?

Though an air impact driver produces the ultimate impact to loosen/tighten the stubborn nuts/bolts, its working principle is very simple! It has a motor operated by an air compressor. The motor spins at a great rotational speed that helps unscrew the bolts/nuts. Side by side, the wrench produces a great torque that pushes the fasteners forward or backward.

The wrench helps both the assemble and disassemble tasks by offering continuous and short bursts. It offers a suitable nut-busting pressure that brings the most stubborn fasteners within seconds. With the help of the compressed air pressure, the unit generates a heavy-spinning torque that can beat almost every nut/bolt/fastener.
