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. For automotive use, as long as you are between 1,000 and 2,000 ft lb of torque, it will be fine in the majority of situations.

Rotations Per Minute (RPM)

The majority of cordless impact wrenches will have around 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.

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.

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.

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.

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. Not only that, it also provides a great warranty plan of 3 years from a trusted brand that has been in the industry for decades.
