Best Cordless Impact Wrench Buyers Guide

Whether you’re a professional or someone stocking up on tools in your new home, you’ll most likely need to get an impact wrench at some point. Some people use these for a little extra power around the house, and some use them for heavy-duty jobs like working on machinery and vehicles.

Understanding the purpose of this tool is one way to make sure you pick up the right one for the jobs you have to tackle.

What is an Impact Wrench?

An impact wrench has a few different names. Some call it an impact driver, impact gun, drill driver, etc. Regardless of how you say it, these tools are there to help drive in screws and other fasteners that would otherwise have a hard time doing with a regular drill.

Impact wrenches provide more strength and power by channeling all their energy into the fastener. How many times have you attempted to drive in a screw or bolt with a traditional drill only to have it whip around and break your wrist in half? I’ve had that happen quite a few times.

For that reason, we have impact wrenches.

When you are driving something in using an impact gun, you’ll notice that once you get halfway into the material, you’ll start to hear these concussive pulses coming from the tool. This is the impact pushing that fastener in the rest of the way. With impact wrenches, you can work with much more challenging material as well as stuck on nuts and bolts.

Using the Best Cordless Impact Wrench

You’ll use an impact the same way you would use any other drill. You’ll secure your energy source whether it be a battery or cord and you’ll go to town. The functions and duties of the tool are exactly the same as any other drill, but the primary difference is the amount of power you get from the device.

We find that many people prefer using an impact even on low-duty jobs because they are easier to work with over long periods. If you are using a standard drill when working for prolonged periods, your arms can get tired because regular drills require you to apply pressure to the material you are working with.

When using an impact wrench, you don’t need to apply any pressure to the material because all the power comes directly from the tool itself. Many impacts also come with an easy way to change bits and sockets.

With a traditional drill, you need to reverse the tool and loosen it so you can remove your bit. With most impact guns, it’s as simple as pushing a button and popping out the bit.

When Should You Use An Impact Wrench?

If you don’t have a lot of experience with this tool, you might be wondering when you should use one compared to when you should use a drill. The primary difference is the material you are working with and how much power you need.

When you are trying to loosen old rusted on lock nuts you would want to pull out your powerful impact wrench. A traditional drill would have no way of removing those. You might even want to use an impact wrench if you are trying to screw into a dense wood. The impact would require a lot less pressure, and it would put a lot less strain on your drill and your body.

You want to prolong the life of all your tools, so it’s essential to always use the right one for the job. Regular drills have their time and place, but when it comes to dealing with the heavy-duty stuff, you always want to have an impact by your side.

Features to Consider When Shopping for the Best Cordless Impact Wrench

While your shopping, you might be unsure about what features matter most to you. You might not know what to look for and what makes an impact wrench different from the next. Here are some of the most essential features to look out for.

  • Batteries – Your cordless impact wrench relies a lot on your battery, (obviously) so you need to make sure that the company uses a high-quality battery. You always want to see that they use a lithium-ion style. These hold a better charge, and they also dish out the power at a steadier rate. This means your battery will last longer and you’ll get more between charges.
  • Comfort – Some impact wrenches are plain ugly, and they are not comfortable to work with. You want to make sure they provide plenty of padding around the grip areas so you can work with them for the entire day without wanting to chop your hand off. The overall feel of the drill should feel nice in your hand while you use it.

Best Cordless Impact Wrench FAQs

How do I clean my impact wrench?

They don’t typically require much service, after each use you can give the wrench a quick wipe down with a dry cloth and you’re good to go.

How does a cordless impact wrench work?

Inside the drill is a rotating mass that builds energy. The mass is then pushed out through the socket in a bunch of unnoticeable but power impacts.

Can my impact remove lug nuts?

Sometimes. Most lug nuts are fastened at around 100 ft/lbs of torque which means you would need a wrench rated to remove that type of torque. Most of the impact guns we reviewed provide more than 100 ft/lbs of torque so you should have no problem.

What is the difference between RPM, IPM, and Torque?

Torque is the power that the impact puts out; this is the best way to determine how powerful the device is. RPM stands for revolutions per minute, and it refers to the number of times the wrench can spin the socket in one minute. IPM is impacts per minute, and it relates to the number of impacts the internal mass has per minute. You mostly have to worry about understanding torque.

 Is a cordless impact better than a corded or pneumatic?

It’s entirely up to personal preference. The general belief is that corded and pneumatic-powered impact guns are stronger because their power source doesn’t wear down over time. That is true. When you are using a corded impact, you aren’t losing torque as your battery wears down.

What you sacrifice for in a little bit of power, you make up for in accessibility and ease of use. You don’t have to worry about having a nearby outlet or tripping over cords. The same goes for the air-powered. You don’t need to have an air supply, and you don’t have to deal with tangled hoses.

Our Verdict

Do you want to know what our final thoughts are on impact wrenches? We believe that they are a necessary tool for anyone doing work around the house or in the shop. At some point in your life, you’re going to encounter a job that requires a little more power, and you’ll be happy to turn around and see your brand-new impact wrench sitting over there.
