Although they’re commonly confused with impact drivers, which have a 1/4-inch hex opening, a cordless impact wrench uses 1/2-inch sockets, and are often used to remove the lug nuts from automobiles. That isn’t the only thing they’re used for, however. They’re actually a very useful tool that can be used for a number of different jobs. Which is why they’re an important tool for just about anyone to own.
Before you can add the power of this tool to your arsenal though, you have to buy a model that is built to do the job right. That’s why we’ve done some research and have determined the best cordless impact wrench models which are currently available. The following impact wrench models are the ones we feel are the best in their class.

How to Buy the Best Impact Wrench
It doesn’t take a lot of research to find a battery powered impact wrench that will suit you. All that’s required is that you take a few moments to determine your particular needs. These type of impact wrenches are an important tool for any homeowner or mechanic to have in their toolbox because it provides them a tool to deal with not only lug nuts but any over-tightened or rusted nut or bolt. Here are a few things to keep in mind when purchasing one of these cordless wrenches.
Impact Wrench Shape & Sockets
Impact wrenches come in two different styles: pistol-grip models and inline models. Pistol style wrenches look like a handgun with a grip that’s seated underneath the motor. Inline wrenches look like oversized screwdrivers which have a grip in the back of them.
For most instances, pistol grip impact wrenches will work just fine. However, inline impact wrenches are often good for getting into tight spaces. Pistol-grip models are easy to use and also fatigue the hands less. That’s why most people start off with a pistol grip model and only add an inline impact wrench if they have a specific need for getting into tight spaces.
Inline models tend to have fewer socket options available than pistol-grip models. Inline grips tend to have 1/4-inch or 3/8-inch sockets. Pistol-grip models, on the other hand, often can use sockets from 1/4-inch up to 1-inch.
Power and Comfort
While some people tend to look for wrenches with the most power, that isn’t the best way to choose a wrench. The best way to choose an impact wrench is to choose one that has just enough power to get the job done. The less power an impact wrench uses, the fewer vibrations it will emit. And fewer vibrations mean that the tool will be easier to hold for longer periods of time and therefore, easier to use.
You also will want to make sure that the impact wrench has a durable construction. Models with brushless motors have fewer moving parts and are generally more durable than other types of wrenches. Also look for models which are constructed with a metal housing and which have over-molded plastic grips.
Torque is one of the most important considerations any potential tool buyers need to make. Without the adequate amount of torque, the tool is not going to be able to do what it was designed to do. That makes it extremely important for you to check out the maximum torque provided by each cordless impact wrench and compare it with other models.
It’s also important to check to see if the impact wrench has multiple settings available. This can also be an important feature. With the ability to select a lower torque when needed, you can save your tool’s battery-life and prevent the bolt from being over-tightened.
Checking the Battery
The last thing to consider before buying one of these tools is what type of battery it has and how this battery performs. While there are a number of different battery types, the most common ones are the Li-Ion battery and NiMH batteries. What happened to the lead-acid and NiCd batteries, you ask? Well, those are still around, kind of, but they are on their way to extinction, so your two basic choices are NiCd and Li-Ion batteries. *(Recommended: battery carrier)
So, you basically have a choice between Li-Ion and NiMH batteries. Which one is better? Well, it depends. Li-Ion batteries are more compact and portable, and they also deliver current for longer periods of time than NiMH batteries. However, they also deliver a smaller amount of current over that time. NiMH batteries, on the other hand, can deliver higher bursts of energy for shorter periods of time, but they tend to be a little bit bulkier. Your particular needs will determine which battery is right for you. However, it should be noted that it may be difficult to find anything but Li-Ion batteries because they are quickly becoming the norm.
