What to Consider When Choosing the Best Cordless Impact Wrench For Automotive Use
To ensure you get the best cordless impact wrench for automotive use, there are some things to consider. Of course, these will depend on your skill level and how you use it, but it’s still a good starting point.
Lightweight & Compact
Holding an impact wrench for long periods can cause fatigue. That’s why it’s important you choose a lightweight model, so you don’t have this issue.
Most of your time will also most likely be spent in tight spaces, which is why we recommend choosing an impact wrench that isn’t too big.
If you’re going to buy an impact wrench, chances are, you expect to be able to use it for years to come. That’s why we recommend sticking with companies that have proven themselves over the years.
All impact wrenches on this list come from reputable companies and, in most cases, come with a warranty.
An impact wrench without power is like an airplane without wings. With rusty bolts being a common problem that mechanics face, it’s important to choose an impact wrench that has a powerful torque and can tackle these types of issues.
Mechanics are constantly dealing with a range of issues that require various torque levels. We advise choosing an impact wrench that allows you to change the speed. Not only will this make your life easier, but it will also prevent the battery from using unnecessary power for certain jobs, providing you with a longer run time.
A lot of impact wrenches don’t include a battery when purchasing. If you’re looking to use your impact wrench straight out the box, we recommend sticking with an option that provides one.
Most impact wrenches allow you to pick between a ‘tool only’ option or with a battery and charger.
When working on your car, you’re going to be spending a lot of time in places with low light making a built-in LED light an optional extra. You will also be able to find bolts that you may have otherwise lost if you didn’t have a LED light.
If you’re going to invest your hard-earned money in an impact wrench, it’s important to look for one that has some built-in safety features. One of these features is ‘overheating prevention.’
While overheating shouldn’t be an issue for occasional use, it could be more of a concern for everyday use.
Similar to the LED light, overheating prevention technology is a great extra but is by no means essential.
Impact wrenches are great tools that allow you to get simple jobs done at a much faster rate. If you have followed the tips in this guide, you should be able to choose a high-quality impact wrench that will stand the test of time.
If you’re still unsure of what to choose, we recommend sticking with the Milwaukee 2767-20 M18 Fuel High Torque as it’s the best option overall thanks to its power, bolt removal mode, and lightweight design.
