Finishing in the Runner-Up position (2nd place) is the Ingersoll Rand W7150. The fact that this is nearly a 5-year-old tool deserves huge props for fighting past these other great entrants. It finished a solid 2nd in power testing and 3rd in repetitive power (speed) testing. It’s the lightest tool of the bunch, weighing only 6.88 pounds, with the 5.0 Ah battery intact.
Torque Wrenches. A torque wrench allows you to apply a precise measure of force, or torque, to a bolt. Use these wrenches when you need to tighten bolts an exact amount, such as in engine repair. Some models have a scale that indicates the torque. Others create a clicking sound when the desired torque is reached. You can also find options with digital readouts for extra precision. 
The hammer mechanism in an impact wrench needs to allow the hammer to spin freely, impact the anvil, then release and spin freely again. Many designs are used to accomplish this task, all with some drawbacks. Depending on the design, the hammer may drive the anvil either once or twice per revolution (where a revolution is the difference between the hammer and the anvil), with some designs delivering faster, weaker blows twice per revolution, or slower, more powerful ones only once per revolution.

The Ingersoll Rand W7150 comes with an impressive design that is built to last - one of the many reasons we’ve deemed it the best product on the market and our top choice. You’ll be able to get the job done with the light but powerful tool. It can generate up to 780 ft-lbs of reverse torque and up to 1100 ft-lbs of regular torque. It will help you power through your jobs and get them done in record time instead of having to do tedious work with a basic model tool. The Ingersoll Rand W7150 is one of the best investments you could choose to make and will always be up to the job - no matter how difficult or complicated.
Our rig combines the front wheel of a car/truck with a weighted sled like those typically seen at tractor-pulls. Although our STR TorQ-O-Matic 5000 testing rig results may not provide a number you can brag about, it does a great job at providing work that levels the playing field on these high torque cordless impact wrenches. As the impact wrench turns the rotor, the weight moves further up the ramp, providing more clamping force on the rotor via the caliper.

Various methods are used to attach the socket or accessory to the anvil, such as a spring-loaded pin that snaps into a matching hole in the socket, preventing the socket being removed until an object is used to depress the pin, a hog ring which holds the socket by friction or by snapping into indents machined into the socket, and a through-hole, where a pin is inserted completely through the socket and anvil, locking the socket on. Hog rings are used on most smaller tools, with through-hole used only on larger impact wrenches, typically ¾" drive or greater. Pin retainers used to be more common, but seem to be being replaced by hog rings on most tools, despite the lack of a positive lock. ¼" female hex drive is becoming increasingly popular for small impact wrenches, especially cordless electric versions, allowing them to fit standard screwdriver tips rather than sockets.
We have nine different cordless high torque impact wrenches from eight different manufacturers, including a couple of the tool-truck brands. Snap-on declined to participate in the best cordless impact wrench shootout, so their placement will remain a mystery. Maybe you can ask your local driver where they would fall. Back to the ones who did enter their trusty steeds.

Open-end and Flat Wrenches. The most basic type of wrench, open-end and flat wrenches have open jaws that slip onto nuts and bolts. Because they can be slim and short, these wrenches are especially useful in tight spaces. They’re not adjustable, so they’re sold in wrench sets of all sizes. They’re available in both SAE sizes, which are expressed in fractions of an inch, and in metric sizes. 
I`m an old fart that started wrenchin when replacing plugs and points was mandtory every 6 months or so. The introduction of battery powered impacts did not impress me at first but the stuff Milwaukee makes is unreal. They now have a big boy I`ve heard twist an unreal 1100 ft lbs!! All there stuff is great, and one battery and “one key” (for tracking) is like si-fi stuff to this old fart. I cant wait till they come out with a 18volt jack with built in jack stand.

An impact wrench can be an extremely useful tool in the armoury of any at home mechanic. After all, we’ve all encountered that rusty bolt that simply refuses to shift, or that upgrade project that needs us to remove and replace about 15,000 bolts. There is however a better way to tackle these jobs that doesn’t result in skinned, bleeding knuckles, tears, tantrums and wrenches thrown through windows.

Many of the points for the Matco Tools impact is lost in the value department, including price and warranty. It was the highest priced of the shootout, by more than $100 ($699 MSRP). It really doesn’t have the features or output to explain the huge price. In addition, the warranty period is only 30 days. Compare this to 5 years with Milwaukee. In the end, the Matco Tools MCL2012HPIWK finished with 70.2 total points.
Wrench, also called spanner, tool, usually operated by hand, for tightening bolts and nuts. Basically, a wrench consists of a stout lever with a notch at one or both ends for gripping the bolt or nut in such a way that it can be twisted by a pull on the wrench at right angles to the axes of the lever and the bolt or nut. Some wrenches have ends with straight-sided slots that fit over the part being tightened; these tools are known as open-end wrenches and are made in various sizes to fit specific bolt and nut sizes.
Regardless of the style of cordless impact wrench that you choose, or what its socket size is, the most important feature to consider is how much torque it generates. When performing a cordless impact wrench comparison, look at the maximum torque that each one is capable of creating. Many of the best cordless impact wrenches feature multiple torque settings making them much more versatile than those with only one torque setting. Setting he torque down only to what’s needed lets your battery work longer and prevents overtightening.
Next, shoppers need to consider the source of power for their wrenches. The most common power source for impact wrenches is compressed air. This provides lower torque capacity than their electric powered counterparts. Electric impact wrenches are commonly used in automotive-repair situations, and they can be 12-, 18-, or 24-volt DC powered. Cordless impact wrenches are also available. Finally, an industrial impact wrench may use a high-speed hydraulic motor. Almost any mechanic's shop you visit will have an impact wrench or two to use, and they are more likely to be electric-corded models or air-powered models.
When a nut or a bolt head is in a recess below the surface of a bolted member, a socket wrench must be used; this is essentially a short pipe with a square or hexagonal hole and either an integral or a removable handle. Modern socket wrenches are made in sets, consisting of a number of short sockets with a square hole in one end that fits a removable handle and 8- or 12-point holes in the other end to fit various bolt and nut sizes. There are several types of handles and extensions, such as a T handle, screwdriver-grip handle, and a ratchet handle (see ratchet).
You asked for it, and we deliver. Our content is full of real data to determine the results in this best cordless impact wrench shootout, so you can make an educated purchase decision. Cordless impact wrenches continue to gain traction with the Pros, so more and more brands are entering the arena. With all the numbers like torque, IPM, BPM, RPM and all the other acronyms thrown around, we do our best to clear the mud.
Over the past two decades we've tested hundreds of tools, but we never ran a competition this close. First, we tightened 38-inch and ¾-inch nuts with a torque wrench. Then we gathered seven cordless impact wrenches and removed the nuts. Somehow there wasn't a single tool with which we had a substantial complaint. We even tried it blindfolded, and could barely differentiate among our top performers. We chose our winner based on subjective measures: how it handled, balance, and grip. In terms of pure performance, though, the 41/2-star machines are just as good. Tools have come a long way in twenty years.

One of the features on the Milwaukee 2767 that stood out is the “Bolt Removal” mode. This was not found on any other impact wrench we tested. On the push-button speed selection at the base of the impact, you can select 1-3. Setting 1 is the slowest and 3, the fastest. The fourth selection is the “Bolt Removal” mode, indicated by a circular arrow designation. When this mode is selected, the user holds their finger on the trigger—once the fastener breaks loose, the Milwaukee senses this and slows the RPM to just 750 to finish removing the nut. This keeps the nut from flying across the shop.
And its steel lined casing will help to protect it from any workplace mishaps that could occur. Additionally, you’ll definitely appreciate the 780 ft-lbs of reverse torque that the machine is capable of generating, as well as the 1100 ft-lbs of nut busting power that it can produce. This product is truly innovative and produces amazing power, making it the highest quality on the market and sealing its place in our list as top choice
We love the DEWALT DCF880HM2 for its simple yet easy to use design and ability to make work easier. It comes with an impressive energy efficiency system that allows you to have 33% more charge than other standard battery packs are capable of attaining. This translates into about 24 hours of work time that you’ll be able to use before the batteries need to be recharged again. You’ll also be able to take advantage of the hog ring anvil incorporated into the design. It makes it easier to do socket changes and get on to other work.
Cordless impact wrenches come in two body styles: inline and pistol-grip. The inline style of impact wrench looks a lot like a large screwdriver, with a grip behind the hammer and anvil. The pistol style is shaped like a handgun, and the grip rests underneath the motor. Cordless impact wrenches also feature a selection of socket sizes designed to fit nuts and bolts of different sizes. The following table shows what socket sizes work with each impact wrench shape. Inline wrenches work best for jobs where you’re working in tight spaces and simply can’t fit a pistol-type impact wrench. If you plan to work on machinery, especially cars, then an inline impact wrench is a must-have tool.
A powered wrench which delivers quick, repeated impulses of torque. Typically powered by air, but can also be electric. Most people have heard its familiar rap-rap-rap noise while being used in an auto repair shop. Although many professionals use them to tighten lug nuts on vehicle wheels, do-it-yourselfers should use a torque wrench since an impact wrench can often over-torque and damage the threads on lug nuts and wheel studs. Impact wrenches are great for loosening stubborn, difficult-to-remove nuts and bolts. power

Remember when we stated there was an exception to the big air power torque? This is it: Ingersoll Rand’s 1/2-inch drive W7150K2 packs a whollop. It has a maximum output rating of 780 foot-pounds and it’s powered by a 20-volt Lithium Ion battery. Part of the secret to it’s big power is the rare earth magnet motor. This isn’t an inexpensive impact wrench, but the kit includes two batteries along with a charger.

A useful accessory for a socket-wrench set is a handle equipped with a mechanism that measures the amount of torque, or turning effort, exerted by the wrench on the nut or bolt. One type of torque handle has two arms attached to the head, which carries the socket that fits the bolt or nut to be tightened; one arm carries the torque-indicating scale and remains fixed relative to the head, while the other arm carries the handgrip and is bent, relative to the head and the scale, when a bolt is tightened. A pointer on the bent arm indicates the torque on the scale. The purpose of a torque wrench is to make sure that screws and bolts in bolted assemblies are installed with sufficient tightness to prevent loosening during use, without being overtightened.
From those visits to unsanitary Houndsley streets in search of Diamond, he had brought back not only a bad bargain in horse-flesh, but the further misfortune of some ailment which for a day or two had deemed mere depression and headache, but which got so much worse when he returned from his visit to Stone Court that, going into the dining-room, he threw himself on the sofa, and in answer to his mother's anxious question, said, "I feel very ill: I think you must send for Wrench.

box-end wrench ring spanner A one-piece wrench with an enclosed opening that grips the faces of the bolt or nut. The recess is generally a six-point or twelve-point opening for use with nuts or bolt heads with a hexagonal shape. The twelve-point fits onto the fastening at twice as many angles, an advantage where swing is limited. Eight-point wrenches are also made for square-shaped nuts and bolt heads. Ring spanners are often double-ended and usually with offset handles to improve access to the nut or bolt. common
The Makita XWT08Z LXT High Torque is a great investment for anyone who needs to do some heavy duty work and is one of the best of its kind. The device is powered by a strong brushless motor that allows it to work harder than other competitive models while maintaining cooler core temperatures. The motor also proves to be energy efficient and can improve the battery run time by up to 50%. You’ll be able to choose from three different speed settings that can attain speeds of up to 2,200 rpm and be able to do some serious work with the power output.

We know it can be difficult to sort through all of the great products they have available to you on the market today – after all, there are a lot of great brands to choose from. But luckily for you, we’ve taken the time to put together a list of the top 10 cordless impact wrenches on the market, as well as a breakdown of what makes each tool so great.


If you have the Matco MCL2012HPIWK impact wrench, then you should be proud of it. It won’t leave someone stranded by not doing work. In fact, when using the Matco Tools impact, it felt like it hit the hardest initially when removing a fastener, and this showed in our speed test. It does lack in the total power department, but that’s not the real reason this impact finished in 8th place.

Where the Ingersoll Rand did suffer a bit is in the feature set area. This is where the age of the tool showed. There is no worklight, it’s only a single speed/mode, and it has a brushed motor. We would love to see a remake of this gun, using the great features as in our review of the Ingersoll Rand W5132 Cordless Impact Review. If Ingersoll Rand will release a new 1/2” high torque, with a brushless motor, multi-speed features, and the halo LED worklight, then first place may be much closer.

While the DeWALT tied for 2nd for features, it did suffer just a bit in the ergonomics category. With ergonomics being a more subjective testing category, users probably need to put the tool in their hand to make their own decision. If you have other DeWALT tools or you think you’re leaning to the DCF899, it’s easy to yes to this impact wrench. Furthermore, you can find the DeWALT stuff about anywhere tools are sold, making it easy for purchase.
wrench The most common type of adjustable wrench in use today. The adjustable end wrench differs from the monkey wrench in that the gripping faces of the jaws are displaced to a (typically) 15 degree angle relative to the tool's handle, a design feature that facilitates the wrench's use in close quarters. The modern adjustable end wrench was invented by Johan Petter Johansson [4]of Bahco. The common use of "Crescent wrench" to describe this design is derived from the Crescent brand, owned by Apex Brands, Inc. Apex Tool Group, LLC. adjustable

I definitely like the mobility of the electric impact, as a road mechanic it’s a lifesaver. That being said their’s nothing like being able to call in for some air support. I’ve had several air impact wrenches throughout the years, from 3/8″ up to 3/4″. I’d have to say Ingersoll Rand makes the best product. Their line of composite guns is my favorite by far. All the torque you need, without all the weight associated with some older models.
