Whether it’s the disassembly of mechanical equipment or the maintenance of automotive equipment, the cordless impact wrench is one of the essential tools.
If you manually remove the screws, how much time will you waste?
Fortunately, we always rely on power tools to accomplish these tasks. Using cordless impact wrenches for automotive applications, it is easy to operate any bolts that cannot be moved.
Before you make up your mind to purchase, please read our purchase guide carefully, otherwise you may spend more money (but not buy the right product).
What You Need to Know About Impact Wrenches
Fortunately, impact wrenches are extremely comfortable to use because the concussive blows smoothly transfer most of that high-energy torque directly to the fastener, not to your hand, wrist, or arm. As a result, the twisting motion—known as reactionary torque—that you feel when using an electric drill is virtually eliminated.
- Batteries: Volts: All things being equal, higher voltage will give you more power—but there are cases for lower voltage. With smaller batteries, 12-volt impact wrenches are more compact. This makes them good for smaller jobs, working overhead, or getting into tight spaces. Tools with 18 and 20 volts have less difference between them. Generally, 18-volt tools with advanced features and capabilities make them more versatile and easier to use.
- Batteries: Amp Hours (Ah): Ah (amp hours) equals the number of amps that can be discharged, continuously, for an hour. Think of amp hours, like the volume of a gas tank—a bigger number equals more gas.
- IPM/RPM: IPM (impacts per minute) increase as RPM (revolutions per minute) increase, and high RPMs help drive nuts or bolts faster, while IPMs kick in harder as the resistance increases.
5 Best Cordless Impact Wrenches 2021:
|Makita XWI11Z||3.6 x 6.5 x 9.2 in||0.16 ounces|
|DeWalt DCF899HB 20V MAX XR||9.9 x 4.2 x 10.6 in||6.4 pounds|

|Porter-Cable PCC740B||9.9 x 3 x 7 in||5 pounds|
|Craftsman C3||16.7 x 9 x 3.6 in||2.2 pounds|
The first thing to mention is that the XWT11Z is only the model number of the tool. It includes two 18V LXT lithium ion 5.0 Ah batteries, charger and soft bag/case.
And Makita’s 18V 5.0 Ah battery (BL1850B) extends run time and charges only 45 minutes.
The XWT11Z fits the smaller end of a 1/2-inch impact wrench, but it’s more than you expected.
When it is activated, the Makita 18V LXT impact wrench will detect when the fastener is loose and will stop spinning.
In addition to power, the Makita is also equipped with three speed XWT11T 18V LXT impact wrenches.
Another innovative feature is the reverse rotation auto stop mode. This feature is ideal for the automotive industry, especially when disassembling engine fasteners.
DeWalt is synonymous with quality and is known for being the best cordless impact wrench.
The DeWalt DCF899HB is the best compact 1/2″ impact wrench on the home and industrial floor market, withstands chemicals, cleaners and greases and can even handle 8 foot drops without damage.
Starting with a heavy-duty impact mechanism, the maximum starting torque is 1200 ft/lb and the maximum torque is 700 ft/lb. The brushless motor’s three-speed selector can be adjusted to handle multiple tasks.
It also has three-speed control to manage your drilling rate accordingly.
In addition, the pigsty can be quickly replaced and the LED work light provides additional visibility with a delay of 20 seconds.
Most importantly, it’s easy to outperform other models at the same level, and it costs several times more.
In short, the absolute strength of this type of impact gun comes at a price, but the price is negligible for what you get.
The Ingersoll Rand W7150’s impressive design and durability make the steel-lined aluminum hammer case sturdy and lightweight, while protecting the internal components of this cordless impact wrench.
In other words, you will be able to focus on getting the job done without worrying about the quality of the tools you are using.
Its finely tuned impact mechanism and motor provide greater torque, durability and efficiency. It produces reverse torque of up to 780 ft-lbs and conventional torque of up to 1100 ft-lbs.

The Porter-Cable PCC740B is the company’s first cordless impact wrench. It’s lightweight and easy to carry, offering some of the best torque.
It should be mentioned that the impact wrench is equipped with a 1/2 inch pigsty anvil to help the motor provide a maximum torque of 330 ft-lbs.
And its variable speed trigger provides 0-1,700 revolutions per minute (RPM) and 0-2,500 revolutions per minute (IPM).
The Porter-Cable PCC740B is powered by a 4.0Ah 20V Max Li-Ion battery pack. The battery lasts longer and the charging speed is faster.
It should be noted that its compact structure can be easily held and used with just one hand, so you can use the other hand to support or hold the lug nut in place.

All in all, the Craftsman C3 Heavy Duty Impact Wrench Kit is a great tool and one of the best investments you can choose.
Impact Wrench Torque
Torque determines the strength of the impact wrench. Simply put, the greater the torque, the stronger the explosive force of the impact wrench.
But not the greater the torque value, the better, this should be chosen according to your specific use. Torque wrenches with high torque are always difficult to control.
Power & Comfort
While some tend to look for the most powerful wrench, this is not the best way to choose a wrench.
The best way to choose an impact wrench is to choose a wrench that has enough power to get the job done. If it is used for a long time, we need to consider its comfort and weight.
Weight & Batteries
As technology has improved over the years, the cost of lightweight lithium-ion batteries has decreased. This means that many cordless impact wrenches are getting lighter and lighter.
Of course, we also need to pay attention to their battery life when buying.
