Automotive Cordless Impact Wrench Buying Guide

The market for cordless impact wrenches is massively saturated with a product for almost all solutions. However, the above are all suited for automotive applications such as changing tires with tough lug nuts being a major problem.

Without a powerful impact wrench for automotive use, you can find yourself struggling to remove old bolts that will simply not budge. It is a tool that you will want alongside your torque wrench in order to work smarter and not harder.

Impact Wrench Torque

The main feature many people will ask is what is the power of the impact wrench. All impact wrenches have a max torque with various torque settings but it is not necessarily a number you should focus too much on.

Over torquing nuts and bolts can become problematic i.e. wheel lugs that are impossible to take off on the roadside. Ingersoll Rand mentioned that over tightening of lug nuts can even cause the wheel to fall off completely.

On the packaging or documentation of the automotive component that you are tightening, you will be able to see the max torque setting. You may be surprised by how little is actually required and this may sway your buying decision if you are purely basing it just on the torque.

Measurements – In-lb & Ft-lb

It is important to make sure that you are reading the correct measurements when comparing between different impact wrenches. Some manufacturers like to define torque ratings in ft-lb whereas some prefer to use an in-lb rating.

Within this article, we have kept to in-lb torque rating but if you divide the rating by 12, you will have the equivalent ft-lb rating of the wrench. Alternatively you can use an inch pounds to foot pounds calculator.

Cordless Impact Wrench For Automotive

Rotations Per Minute (RPM) & Impacts Per Minute (IPM)

The majority of cordless impact wrenches will have around 2,500 – 3,000 RPM’s with the more RPM resulting in less user effort. Variable RPM is a feature that is found on some impact wrenches, which can be particularly useful for rusted bolts where a lower RPM is more appropriate to prevent damage to the bolt.

Often confused with RPM is the IPM (Impacts Per Minute) rating, which is the amount of times it hits the anvil in a minute. The higher the IPM means that the wrench should be able to overcome much larger resistance.

Weight and Batteries

The benefit of a cordless impact wrench over the corded alternative is that its more portable. However, if it weighted down by a heavy battery it can seem pretty pointless because you will need to give your arm a rest during long periods of use.

As technology has improved over the years, the cost of lightweight Lithium Ion batteries has decreased. This means a lot of the corded impact wrenches use this type of battery to ensure the complete weight of the battery is a light as possible.

All the batteries will be given an Ah rating, which is the “Amperage Hours” of the battery. The higher the Ah rating will reflect on how long the charge will stay with the battery. Overtime batteries do lose their charge and this is a big factor to consider.

It is also important to remember that some manufacturers will show different weight ratings. They will either be the bare tool or the tool combined with a battery. Be sure to compare between tools respectively if weight is a big issue.

The Voltage

Most cordless impact wrenches are either a 18V or 20V with the latter being the more powerful. You can find the voltage printed on the tool itself (as shown below) or on the battery of the cordless impact wrench. For automotive use, voltage of 16V to 20V will be ideal but in other applications, a higher voltage may be required. Higher voltage tools often come with an inflated price and this may be something to consider.

Electric Impact Wrench

1/4, 3/8 or 1/2 Inch Drive

The drive size of a cordless impact wrench increases the torque performance with the larger (1/2 inch) offering greater strength. It does vary depending upon your usage and the type of applications that you will be using the tool.

Intuitive Design Features

The basic design of an impact wrench is fairly similar between the brands but some do offer other design features. For example, the Bosch IWBH182B recommendation offers an extra small grip diameter so that it is easier to hold for long periods.

Many of the premium options come with LED lights that are directed towards the work area to help with poor lighting conditions. Spending the small amount extra can make a huge difference and improve your work rate.

Air vs Cordless

For most light automotive tasks such as lug nuts, suspension or body work, using a cordless impact wrench is the best option. However, for certain heavy duty tasks, the air powered alternative may be the better option due to the increased torque ratings.

However, you can have the best air impact wrench available but it will not be as portable or maintenance-free as a cordless impact wrench.

Conclusion

If you are looking for brute force and ease of swapping the nuts from the impact wrench, then the Milwaukee M18 is the one due to the monster power that it has. However, the overall favorite is the Dewalt DCF883HM2 because it is great for everyday use that you may carry out, from heavy duty to DIY in the house.

All of our recommendation in the article are suited to different applications of use. Professionals that work within the automotive industry may prefer the heavy duty Ingersoll Rand W7150-K2 but of course, this will not be suited to those on a budget.

If you are fed up of tight bolts that simply wont shift, then investing in the best cordless impact wrench can make a huge difference. They are relatively expensive but they will last many years of heavy usage unlike many other tools.
