Throughout the years, impact wrenches were tools mostly sold for auto repair shop use. The main reason was that they were air or pneumatic powered, and not a lot of people had big enough compressors laying around, or even the space to store one. Even if you did, the overall process of installing the system and using it was often far too expensive for weekend DIYers.
However, for the past decade or so, batteries became more efficient, compact, and reliable. Consequently, tools like cordless impact wrenches, powerful enough to change tires, became available to the masses.

Reviews of the Top Cordless Impact Wrenches for Changing Tires1. Milwaukee M18 FUEL w/ONE-KEY Cordless 1/2 in. Impact Wrench — Premium PickThe first one on this list is the Milwaukee M18 FUEL. It is a one-key operated impact wrench that can deliver fastening torque of up to 1000 ft-lbs and a nut-busting torque of 1400 ft-lbs.
These numbers make it the most powerful impact wrench on the list. However, that much power also means a slightly bigger and heavier machine. With a length of 8.39 inches and a weight of 5.9 pounds, you are looking at one of the heavier contenders here.
The M18 features a clip-on 18-volt battery on the bottom of the handle, powering a brushless electric motor. There is also a friction ring at the end of the shaft, ensuring that the sockets don’t fall off while spinning.
A unique feature the Milwaukee M18 has is the one-button control. It enables you to connect the impact wrench via Bluetooth with your phone and control it from there. You can control the speed and power you need based on the application. The Milwaukee M18 impact wrench enables you to preprogram up to 4 different torque settings for quick use.
This function is especially useful to select different torque settings for repetitive operations. If you are a professional mechanic, you’ll like this one. You can pre-select the first setting at 90 lbs and another at 110lbs, so you can quickly change tires on cars and trucks.
No reason to buy an expensive set of Accutorq anymore!
And another nice touch; the Milwaukee M18 also has a built-in GPS tracker to help you find it. Yeah, it happens to me too.
That’s personally the model I’ve been using for the past 5 years and there’s no going back to my old air-powered impact wrench now.

2. Makita XWT15Z 18V LXT® Cordless 1/2 in. Impact Wrench — Budget PickNext on the list is the Makita XWT15Z, good enough for a tightening torque of 240 ft-lbs and a nut-busting torque of 430 ft-lbs.
This one is a bit on the smaller side but not every job requires 1,000lbs of power.
The motor is powered by an 18-volt 5 Ah battery, which, combined with the technology used to build it, provides longer run-time. Furthermore, the package is reasonably compact, with a length of a little under 6 inches, weighing around 3.5 pounds.
The XWT15Z has a selector switch changing the speed and three forward and reverse modes, each for improved efficiency. For example, one of the settings reduces the trigger travel when you need to use full power.
Unlike the previous impact wrench, this one has a detent anvil to keep the socket on the shaft. The detent is really a question of taste. I personally prefer friction rings but some might say I’m wrong. You be the judge.
The Makita XWT15Z also comes with front LEDs that will help you work in darker environments, and, luckily, it has a dedicated on/off button. I don’t know about you but I really hate models with LEDs that only light up when the trigger is pressed.
We need some light before the socket is on the bolt! Anyway, I digress. Moving on.
The Makita is designed with XPT or Extreme Protection Technology, meaning it provides additional protection from dust or water, so it’s great for use in non-ideal environments.
The XWT15Z is a good impact wrench for beginners, weekend DIYers, and as a second impact for professional mechanics. It’s simply perfect for everyday work when you still need a little more power than a 3/8-drive impact wrench but doesn’t want to strip every bolt in your way.

3. DEWALT DCF890M2 20V MAX XR Cordless 3/8 in. Impact WrenchWhen it comes to light and long-lasting impact wrenches, Dewalt MAX XR is the one to go.
Yes, it’s a 3/8-drive model so it might not be suitable for professional mechanics changing tires all day. But if what you need is a smaller model to change tires once every 6 months, this one might be a good idea.
The brushless electrical motor in this puppy can put out up to 150 ft-lbs of torque in both directions, drawing power from a 20-volt battery. And it’s quite compact, measuring only 5.5 inches long and weighing just 2 pounds.
The Dewalt MAX XR comes with different power settings and the trigger is variable. Just like you’d expect, there are several speed variations you can use. The good news is that the speed at which it will run will depend on how much you press the trigger, which has an excellent weight. Just like the Milwaukee model above, the Dewalt MAX XR is a 3/8-inch impact wrench that has a hog ring anvil that keeps the sockets in place.
Moreover, the 3 LEDs on the front help with non-illuminated spots, while the lightweight and ergonomic handle makes it easy to maneuver.
In the package, you get the tool, along with two batteries, a charger, a belt clip, and a tool bag.
You simply can’t go wrong with this one!

4. Ingersoll Rand W7150-K1 High-Torque Cordless 1/2 in. Impact WrenchOn the opposite side of the torque spectrum, we have the Ingersoll Rand W7150-K1. This massive impact wrench comes with a 3 Ah 20-volt battery that powers a motor capable of putting out 780 ft-lbs of tightening and 1100 ft-lbs nut-busting torque.
However, the increased power means that it is significantly heavier and bigger. The head length measures a little under 10 inches, and with the battery installed, it weighs 6.
8 pounds. At the tip of the shaft, you have a 1/2-drive friction ring anvil to hold sockets in place.
Even though it is over three times heavier than its competitors, the rubberized handle makes it comfortable to hold.
Since it’s longer than the others, Ingersoll Rand designed the inside components to be evenly balanced, reducing strain on your wrist. The W7150-K1 also has a soft-mount system on the motor and an impact system reducing vibration.
If you really need an impact wrench that’s on the bigger side while being smooth enough to be used all day, the Ingersoll Rand W7150-K1 is what you need.

5. CRAFTSMAN CMCF900M1 V20 Cordless 1/2 in.
Impact Wrench — Editor’s PickIn many ways, the CRAFTSMAN V20 has a few similarities with the Ingersoll Rand W7150-K1. However, it’s several inches shorter, measuring only 7 inches, and considering the size, the weight is also lower at 4.66 pounds. Meanwhile, the brushless motor can put out a maximum torque of 350 ft-lbs.
It comes with a 4 Ah 20-volt battery, ensuring that you get decent power and longer battery life than others. As a bonus, the included charger can top it off in about 60 minutes. The CRAFTSMAN V20 also has a variable speed trigger for better control and preventing over-tightening.
Considering the size, it may not fit in the tightest places as other impact wrenches on this list. However, the CRAFTSMAN V20 is not designed to be used for that anyway. If what you need is a powerful impact wrench to change tires all day, get this one. If what you need is a lightweight and compact model, get another one on this list.
Simple as that!

6.
PORTER-CABLE PCC740LA 20V Cordless 1/2 in. Impact WrenchThe PORTER-CABLE 20V MAX comes with a 20 V 4Ah battery that powers a motor capable of putting out 260 ft-lbs of torque. The combination will get you a well-powered impact wrench with longer battery life.
Furthermore, the motor can spin the shaft at 1650 RPMs and 2500 IPMs, while the variable speed trigger will help you control the speed with greater precision. At the end of the shaft, you get a hog ring, making socket replacement relatively effortless while keeping them firmly attached when spinning.
The 20V MAX impact wrench has a specially designed protective housing, shielding it from liquids and dirt. Also, considering the length, the internal components are evenly balanced, reducing strain, while the molded handle will provide excellent grip.
The PORTER-CABLE 20V MAX is a direct competitor to the CRAFTSMAN V20. Dimension-wise, the PORTER-CABLE’s head measured at 9.9 inches, weighing 6 pounds with the battery attached.
It’s a bit bigger than the V20 but a little smaller than the Ingersoll Rand W7150-K1. Let’s just say that it’s a good mid-level option.

7. Ridgid R86011B 18V GEN5X Cordless 1/2 in. Impact WrenchLast but not least is the Ridgid R86011B OCTANE 18V churning out 485 ft-lbs of tightening torque and 620 ft-lbs of nut-busting torque. It also has a hog ring anvil like most models on the list.
When it comes to size and weight, it closely matches the CRAFTSMAN V20. The head’s length is 7.7 inches, and the weight is a little under 4 pounds with a battery. Unlike the previous models, it comes with an 18V battery. It’s not the best but should suffice for most use-cases.
On the other hand, if you were planning to use it 40 hours a week at work, maybe choose a different one or buy 2 batteries, just in case.
You can operate the speed via a 4-speed button on the side. There is also an auto mode that turns off the tool as soon as you tighten the bolt to prevent overtightening.
The last 3 impact wrenches on the list are somewhat similar. It’s really a question of taste. As I said before, I prefer the Milwaukee one, but I know a couple of mechanics who prefer to have a bigger model when changing tires.

Things to Consider When Buying A Cordless Impact Wrench for Changing TiresWhen you are on the market and looking to buy a new or replace your existing impact wrench, there are several things you should consider.
As you can see from the products’ outline in this article, the torque numbers vary significantly, while the RPM and IPM numbers don’t. These are the most important consideration you’ll probably need to make.
Overall, for home or construction use, you will probably be fine with any of the impact wrenches on this list, even the smaller ones. On the other hand, if you are a mechanic and change tires professionally, you should aim for the more powerful ones.
SocketsIn most cases, impact wrenches don’t come with the sockets included. While some manufacturers can sell you a bundle, it is more likely that you only get the tool.
If you are replacing your old impact wrench, you might already have the sockets. However, you need to make sure that the anvil size is the same. Just make sure that you buy an impact wrench fitting the sockets you have.
On the other hand, if you are a mechanic, you already know what you need – one of each!
Battery sizeConsidering that these are wireless impact wrenches, the battery will limit you regarding run-times.
The size of the battery can drastically change your usage time. It shouldn’t really be a problem if you only use your impact on weekends and only change one set of tires. However, professional mechanics should aim for at least a 20V, or buy more than one battery pack.
Keep in mind that some manufacturers sell more than one battery in the package. Doing so is extremely handy since you can use one battery while you charge the second one and switch when it’s dead.
Since the batteries are removable, you have the option to get a bigger battery. While most impact wrenches in this article come with either 3 or 4 Ah batteries, you can check the manufacturer to see if they offer more powerful ones. Alternatively, you can try to find a third-party manufacturer that sells compatible kits. However, keep in mind is that using a bigger battery will also increase weight.
Weight and sizeWeight is not something you should take lightly when shopping for an impact wrench.
The lightest one on the list is 2 pounds, while the heaviest is well over 7 pounds. When you work with a heavier tool, your wrists will get exhausted faster.
Even though the impact wrenches here are used to remove lug nuts, if you have them in your garage, you will most likely use them for other jobs. The sheer size plays no role in removing the nuts on your tire, but it can be a problem for tight spaces. Impact wrenches with longer heads will be more difficult to maneuver into certain places. Unfortunately, more powerful models often come in bigger sizes.
There’s always the right tool for the right job. Smaller jobs require a smaller impact while tough work do better by a larger one.
Additional featuresNo additional features will ever make an impact wrench reach the top of the list. However, model-specific features might sometimes be a deciding factor.
LEDs on the housing are a great addition that will help you see in front of your impact wrench.
This might be especially useful if you frequently work in a dim-lit area. Unfortunately, not all impact wrenches have them.
Another thing to consider is how the speed of the shaft is controlled. Some of them have a dedicated button with several speed options, while others have a pressure-sensitive trigger. In this case, it boils down to personal preference.
Garages are not a place for delicate tools, and most manufacturers know that. While all of them will have no problem dealing with regular use, some are designed with casings that could protect them from water and dust. If you work in an especially dusty location such as an auto body repair shop, dust protection might be worth considering.
Final VerdictWhile all the impact wrenches on this list are very capable to tackle pretty much anything you’ll throw at them, some are more suited for a specific type of person or type of work. If you are buying your first impact wrench and only use it occasionally, the Makita XWT15Z might be the one for you.
On the other hand, the DEWALT 20V MAX XR is perfect for ATVs and UTV and any smaller equipment.
That being said, if you are a professional auto mechanic, removing and reinstalling tires all day, every day, the Milwaukee M18 FUEL is what you need! Trust me; it’s a little more expensive than most but you’ll thank me later.
Of course, this isn’t an exhaustive list and it’s super suggestive. If you are using a different model and think it’s even better than the ones I pulled out here, make sure to leave a comment below. I’d like to see what you guys use!
Historically, impact wrenches were predominantly pneumatic, or air powered, which left them squarely in the domain of professional mechanics. To run a typical 1⁄2-inch pneumatic impact wrench, you usually need an air compressor putting out close to 100 psi—a significant investment.
The good news is that cordless, battery-powered impact wrenches have gotten better as battery technology improves, which has brought prices down and made them viable alternatives to their pneumatic cousins.
In fact, cordless impact wrenches have a tremendous advantage: mobility. Not being tied to a compressor with an air hose, these tools can easily go wherever they’re needed.
We called in a range of impact wrenches—from a heavy-duty, high-torque model down to a compact, medium-duty model—and subjected them all to the same challenges to identify their strengths and weaknesses. Read on for some buying advice, followed by our findings and reviews of the best impact wrenches.

Unlike cordless drill/drivers and impact drivers, which excel at drilling holes and driving screws, the impact wrench is specially designed for tightening and loosening various hex-head bolts, nuts, and lag screws. It employs both rotational force (torque) and short-burst concussive blows (impacts) to deliver an unparalleled amount of power. For example, most cordless drill/drivers produce about 50 foot-pounds of torque, and the average impact driver delivers about 125 foot-pounds. By comparison, cordless impact wrenches can easily produce torque outputs of over 250 foot-pounds, which is more than enough muscle to power-drive the fattest lags and bust loose rusty, corroded nuts.
However, all that brute strength isn’t very useful if you can’t control the tool. 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.
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.
Amp hours (Ah) equals the number of amps that the battery will discharge, continuously, for an hour. Think of amp hours like the volume of a gas tank—a bigger number equals more gas.
Impacts per minute (ipm) increase as revolutions per minute (rpm) increase. And high rpm help drive nuts or bolts faster, while ipm kick in harder as the resistance increases.
Every impact driver on this list has been thoroughly vetted and evaluated by our test editors. We research the market, survey user reviews, speak with product managers and engineers, and use our own experience operating these tools to determine the best options. We chose practical tasks that most people might need to accomplish with these impact wrenches. The first was removing and replacing lug nuts torqued to the recommended spec at 165 foot-pounds on a Ford F-250 Super Duty pickup truck. The second task was to remove, or break free, rusted nuts and bolts on an old piece of farm equipment. We evaluated them on performance, price, comfort, value, and versatility to determine the best impact drivers that will meet the needs of a wide range of people.

The history of car tires At the present time, you can’t find a person who doesn’t know what tires on cars are for. But not everyone knows that tires have become such relatively recently. To trace the history of automobile tires, it is necessary to go back almost a century and a half into history. nine0003
The first rubber tires appeared in the middle of the 19th century, almost immediately after Charles Goodyear's invention of the process of making rubber from rubber. Initially, such tires were wooden wheels, on which a rim made of a solid rubber layer was put on. Molded rubber tires were a breakthrough in ride comfort, allowing for a slightly cushioned ride while absorbing bumps from bumps in the road. However, although the use of molded rubber tires reduced shaking and vibration, the ride on a vehicle with such wheels was still far from comfortable. nine0003
Solid tire
It is believed that the idea of using a layer of air to cushion impacts and reduce rolling friction came from the Scottish engineer Robert Thomson, who received a patent on December 10, 1845 for the invention of an "improved wheel for wagons and other moving objects."
Thomson's "Improved Wheel" consisted of a wooden rim covered with a metal hoop, onto which an outer leather cover was screwed with bolts. From the outside, pieces of leather were fastened with rivets. Inside the resulting leather tube was placed the prototype of the modern camera, only at Thomson it was made of canvas impregnated with a rubber mixture. nine0003
Tire Robert Thomson
Thomson even conducted tests that showed that the use of an "air wheel" can significantly reduce the force required to move the crew. Thomson intended to use similar wheels on carriages, especially noting that the carriage could now move especially smoothly and that, thanks to the use of air tires, it seemed to hover above the ground. Robert Thomson published his test results on March 27, 1849.year in Mechanics Magazine, with detailed drawings and a description of his invention.
However, no one was interested in this invention, and the production of "air wheels" was never started.
The pneumatic tire was reinvented in 1888 by John Boyd Dunlop in Ireland. Dunlop's first pneumatic wheel consisted of an air-filled piece of garden hose fitted to the wheel rim of his son's children's bicycle. The hose was attached to the rim with a wound tape made of rubberized canvas. To prevent the tape from quickly abrading on the road surface, Dunlop attached a piece of thick rubber tape over the wound canvas tape. nine0003
John Dunlop's tire
In 1889, a bicycle race was held, which was won by a rider who used an unusual tire on his bicycle - with a pneumatic tube.
Realizing the promise of his invention, John Dunlop opened a workshop for the production of pneumatic bicycle tires in 1889 - "Pneumatic Tire and Booth's Bicycle Sales Agency". Now this company has grown from a small workshop into the international Dunlop corporation. nine0003
However, the pneumatic tire could not be used on cars in that form. In addition, the tire was non-removable, which caused great inconvenience during operation. After a very short time, in 1890, the problem was solved with the adaptation of the tire for mounting on cars. Engineer Kingston Welch proposed a new scheme for the wheel: tires were made removable, separate from the camera. Metal wire was inserted into the edges of the tire for strength. Thanks to the recess, the camera was better fixed on the rim. To prevent the tire from slipping off the rim, its edges protruded and held the sides of the tire. nine0003
Kingston Welch Tire
In the same year, methods were developed for relatively easy mounting and dismounting of the tire. The beginning of the use of pneumatic tires on cars was already a matter of time. It only remained to adapt the design for use on cars with their high (for that time) speeds and heavy wheel loads.
The first automobile pneumatic tires were produced by two French brothers Andre and Edouard Michelin, presenting them in 1895 years before the Paris-Bordeaux race. The brothers already had experience making bicycle tires. They made car tires specifically for this race. Nowadays, almost everyone already knows the name of the brothers - the Michelin company has grown into an international corporation.
Thanks to the use of pneumatic tires, the cars have increased smoothness and maneuverability, driving on rough roads has ceased to be so unpleasant. However, the general distribution of such tires was hampered by their capriciousness in operation, as well as difficulties in mounting and dismantling. Therefore, solid rubber and pneumatic tires were produced in parallel. nine0003
Further research by engineers to improve pneumatic tires was aimed at eliminating the above shortcomings. Soon, special strips made of various reinforcing materials - cords - were introduced into tires, which increased the service life and unpretentiousness of the tire. The appearance of special assembly machines significantly accelerated the installation / dismantling of wheels. Among other things, the wheels themselves are removable. Now they were attached to the hubs with a few bolts.
Pneumatic tires were soon strong enough to be used on trucks. The number of tires produced already numbered in the millions. nine0003
To improve handling, various tread patterns were developed, research was carried out with various rubber compounds. Synthetic rubber has been developed to reduce dependence on countries that supply natural rubber used to make rubber. This made it possible to reduce the cost of tires, as well as to stabilize the chemical composition of rubber, which made it possible to achieve constancy of chemical and physical characteristics for each tire in the series.
Chemical companies have been actively involved in improving the quality of tires, not only by selecting new rubber additives, but also by finding the best cord material. Initially, the cord was made of textiles, but it had low strength, which is why there were frequent cases of tire ruptures. Company engineers began to experiment with synthetic materials - the latest viscose and nylon. The use of these materials made it possible to significantly increase the strength characteristics of tires. Now cases of tire explosions have become a very rare occurrence. nine0003
In the middle of the 20th century, Michelin developed a completely new type of tire: the cords were made of metal and ran radially from bead to bead. Tires with this type of cord are called radial. The use of a radial cord made it possible to increase the strength and service life of the tire several times with the same weight. Or, while maintaining the same strength and speed characteristics, have a much smaller mass.
For all its merits, the traditional tube tire has one major drawback: when punctured, it deflates almost instantly and movement becomes impossible. To get rid of this shortcoming, it was necessary to find a way to do without a camera. And therefore, tubeless tires were developed, which, even in the event of a puncture, made it possible to drive some distance without a significant loss of their strength qualities. However, tubeless tires are more demanding on the quality of both the tire itself and the disc. All this is due to the fact that in such wheels the tire must fit as tightly as possible in the disk machine to ensure the necessary level of tightness in order to keep the air inside. nine0003
High profile tire
Modern car owners will find it surprising, but until the 60s of the 20th century, the tire profile was almost a circle. Further, the tire height decreased all the time, sometimes reaching 50 percent of the profile width. Low profile tires have better traction due to the larger contact surface. In addition, due to the reduction in the height of the profile, directional stability has improved, since such a tire is less deformed under side loads. A low-profile tire has many advantages, including a custom look that gives a car with such wheels a certain sporty aggression. But we must remember that in this case it is necessary to sacrifice the maximum load capacity. Although this is far from the most important criterion for sports cars. When tuning, car owners often put "sporty" low-profile tires even on cars that do not have a "sporty" appearance. But here it is already a matter of taste. nine0003
Low Profile Tire
Since the advent of the first "air wheel" and until today, research has been ongoing to improve the consumer qualities of pneumatic tires. If earlier research was mainly in the direction of increasing the strength of tires and improving grip on the road surface, now this has been added to the desire to create a tire that causes minimal environmental damage. This includes not only environmental friendliness in manufacturing (tire production has historically been very environmentally dirty), but also minimal harm in operation (peeling pieces of rubber and gases released are important environmental pollutants). In addition, do not forget that after the termination of use, the tires must be disposed of somehow. This process is also far from safe for the environment. nine0003
Previously, people did not think about the damage caused by humanity to the environment. But now, fortunately, things are changing for the better.
