This review focuses on the best models of cordless impact wrenches. Initially such wrenches were mainly pneumatic (air-powered) instruments used by professional car mechanics. Contemporary cordless impact wrenches go even further because they work from battery-powered motors.

Advantages of using cordless impact wrenches:

  • User-friendly tools. Expert car mechanics and novice amateurs can use these wrenches without any problems;
  • Good for removing lug nuts from tires. Make sure to hold one of these wrenches in your trunk to make the replacement of a damaged tire easier;
  • Speed. These instruments are quite fast and effective at the same time;
  • Can remove and tighten bolts. Unlike other wrenches, these cordless impact tools are capable of tightening and removing lug nuts, screws and bolts;
  • Mobility. These cordless tools are more portable because they are not connected to an air compressor and you may take the tools whenever you go;

How do cordless impact wrenches work?

Compared to impact drivers and cordless drills, cordless impact wrenches were specifically designed to loosen or tighten different hex-head bolts, lug nuts, screws and other fasteners. This instrument uses torque as the rotational force and impact (short-burst concussive blows) to deliver an unprecedented amount of power.

For instance, most cordless drills can produce no more than 50 ft.-lbs. while any average cordless impact wrench can easily deliver about 250 ft.-lbs. Thanks to such an enormous muscle power transformed into torque you may easily loosen even the rustiest bolts and fattest lag nuts.

Five cordless impact wrenches were picked for the test and then they were reviewed. The strong and weak points of each instrument are listed along with personal expert reviews. Check the comparison table and the buyer’s guide to pick the wrench according to your needs.

The Buyer’s Guide

There 4 major factors to consider when you choose a cordless impact wrench:

  • The higher power, the better. A powerful impact wrench should deliver 200 torques at least;
  • High RPM (rotation per minute) – over 3000. Such high RPM can exclude the risk of human errors;
  • High IPM (impact per minute) is another factor that affects the reduced risks of human errors;
  • Weight – a good cordless impact wrench should be lightweight and portable if you want to apply as less effort as possible;

Besides these factors, check the following things when buying a cordless impact wrench:

The motor type

All these wrenches can offer one of two motor types – non-brushless and brushless. Typically, most tools have brushless motors because they are more powerful and effective. Also, brushless motors tend to serve longer and work quitter. However, non-brushless motors are less bulky and come with more affordable tools.

Power

What makes cordless impact wrenches unique is how they can smoothly transfer high-energy rotational power directly to the fastener instead of your hand or wrist like other wrenches do. It means that the use of this tool takes less effort and time to tighten or loosen even the most “stubborn” bolts.

Surely, such power is achieved to the sophisticated design of cordless impact wrenches. Such tools mostly work from batteries. Two important factors should be considered when you choose the battery-based impact wrenches for your toolbox:

  • Volts of the battery. The higher voltage can deliver more power. But the wrenches with smaller voltage and batteries (for 12 Volts) tend to be more portable. You may use such lightweight tools for smaller projects. Also, pick one of these instruments when you need to work overhead safely. However, 18-volt wrenches can offer more versatile options and user-friendly features;
  • Amp Hours (Ah) is another important thing to check in the tool’s battery. This number shows how many amps can be discharged per 1 hour of intensive work. Basically it resembles the volume of a car’s gas tank. If this number is large, the tool has to work without any recharge;

Most batteries inside such wrenches are easy to change – just pick the batteries made by the same brand. The battery type is usually Lithium-ion. However, such batteries won’t last more than a few weeks if you use the tool daily.

Drive size

Just like all wrenches, these instruments come in different drive sizes for different bolts and screws. Mostly, cordless wrenches come with adjustable drive sizes. The higher the drive size, the higher the torque is. That’s why it would be wiser to stick to 1/2-inch drivers. If you need smaller drive size – 1/4-inch or 3/8-inch – consider choosing the wrench with adapters.

To define the torque range and drive size for the bolts you need to tighten or loosen, use a torque angle gauge before applying a wrench. Otherwise, you may break the but if the drive size or torque range is large.

Uses

Typically cordless impact wrenches are required when a mechanic needs to put it or take out screws, bolts, lug nuts in vehicles as aircraft machines, autos, bikes, boats, etc. Most pulse-type wrenches are used when you need to change the wheel’s tire and then assemble the parts with properly tightened bolts.

Besides auto repair shops and garages, these tools are also frequently used in home construction when you need to tighten lag-bolts securely into beams/posts. Also, it is a great tool to remove tight bolts in very sturdy columns and steel structures.

Final thoughts

If you don’t have much hand muscle or space in your garage, consider using cordless impact wrenches. They are quite simple to use, portable because work without a cord and do not need you to apply a lot of muscle power to loosen or tighten even the largest bolts. These comparatively affordable instruments can really make your life easier if you regularly repair your car or just need to change the tires from time to time.


I’m a Matthew Johnson, and I’m a motor mechanic. I like my profession and every day I use many tools, but a torque wrench is most useful of them. I’m going to write about my experience of using different torque wrenches and share with you.

  1. I know that some people prefer the Milwaukee 2767-20 M18 but I think my DEWALT DCF899B is the best cordless impact wrench. I’ve had it for some time and it never failed me and I recommend it to anyone wanting to go cordless.
