When compared to many other power tools, cordless impact wrenches are quite specialized in what they do. Large nuts and bolts may not need to be removed or tightened as often as smaller screws. But when you do need to adjust one, a cordless impact wrench will save you both time and energy. They can also loosen and tighten nuts and bolts much more accurately than hand tools such as sockets and ratchets, which is critical when it comes to working with larger bolts or on machinery.
We used a 10-inch x 10-inch I-beam made with 1/2” (.470) steel. The I-beam has ten (10) grade 8 hardened bolts with a 7/8” diameter inserted, along with appropriate nuts and washers. The torque specification for this size bolt is 454 pounds. This means that at 454 ft-lbs of torque, the bolt is in its elastic or stretched state. We pushed the limits a bit and torqued all ten bolts to 500 ft-lbs for each impact wrench.

An over-tightened or rusted nut or bolt that’s stuck can be one of those things that makes you realize you need to add a new tool to your kit. One of the best models for the job is a cordless impact wrench. This useful equipment has more torque than most drills and it can take care of a stuck nut or bolt in a matter of minutes, saving you time and frustration.

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.

Adjustable Wrenches. These tools have one stationary jaw and one adjustable jaw that can fit a variety of different nut sizes. When you use an adjustable wrench, make sure you’re turning the tool toward the adjustable side, putting pressure on the stationary jaw. This will prevent you from stripping or rounding your fastener. These wrenches are a great choice for any toolbox because you’ll always have the wrench size you need. 
Old English wrencan "to twist," from Proto-Germanic *wrankijanan (cf. Old High German renken, German renken "to twist, wrench," Old English wringan "to wring"), from PIE *wreng- "to turn" (cf. Sanskrit vrnakti "turns, twists," Lithuanian rengtis "to grow crooked, to writhe"), nasalized variant of *werg- "to turn" (cf. Latin vergere "to turn, tend toward"), from root *wer- (3) "to turn, bend" (see versus). Related: Wrenched, wrenching.
As one of the few subjective areas of our testing, we do our best to still quantify our results by including many users and data logging the results. Even though cordless tools are getting a bit smaller and lighter, due to technology, the cordless impact wrenches still have some weight and girth. Using a heavy tool can be a real pain, so it makes sense to place value on the fit and comfort of such a tool. More than just weight, balance, and vibration also play into our testing.

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.
The fact that the Milwaukee 2763 Gen 1 high torque now has a stronger big-brother, but still finished 3rd deserves big kudos. In fact, receiving 86.1 points, it only misses 2nd by 0.3 points. While some others above suffered by finishing mid-pack, this is actually a plus for the Milwaukee. The difference is, the 2763 didn’t drastically fall short in any area, like the others. Even though the price is higher than several, with it’s 5-year warranty, features, and ergonomics, it’s still a great value.

A total length of barely 5 inches and a weight of less than 3 pounds means this tool is one of the few things around that is actually smaller than your Dad’s… ego. Jokes aside, if you need a tool to fit into tight spaces, this could be the one for you. It also boasts a comfortable ergonomic grip, a 3x speed power selector for effective control and the brushless engine we like to see.
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.

open-end wrench open-ended spanner A one-piece wrench with a U-shaped opening that grips two opposite faces of the bolt or nut. This wrench is often double-ended, with a different-sized opening at each end. The ends are generally oriented at an angle of around 15 degrees to the longitudinal axis of the handle. This allows a greater range of movement in enclosed spaces by flipping the wrench over. common

Inside the tool is a rotating mass. A cordless impact wrench uses batteries to generate power. The motor builds up energy using the rotation and then pushes it into an anvil that’s located at the end of the tool. This creates an enormous amount of torque, more than can be produced by any human. The mass, which is shaped like a hammer in the best cordless impact wrenches, continues to rotate, so the operator only feels a tiny amount of the impact.
Great comparison test, better than the others I read online. I ended up buying the first gen Milwaukee, which is still a great gun. I used a co-workers and was impressed pulling lug nuts off a one-ton dump truck. I was able to get the gun, hard case, set of Milwaukee-branded impact sockets, two 5.0Ah batteries, the charger, gun nose protection boot, and Milwaukee LED worklight for $450. Too good a deal to pass up.
Jobs that require the power of an impact wrench usually entail using them for many operations over an extended period. Ergonomic handle grips and anti-vibration measures help to reduce work-related strain. Additionally, you should pick a cordless impact wrench with just the right amount of power necessary to perform the job properly. A smaller motor tends to mean fewer vibrations, which in turn lessens the physical strain.
There are many reviews and head-to-head impact wrench tests that already exist. Most of these tests include the Skidmore Wilhelm torque testing equipment. By turning a large nut, you raise the needle on the PSI gauge. Then, dividing by a factor provides a “torque” number. While these tests do a great job at validating (or not) manufacturer calculated numbers, we felt there were better ways to demonstrate raw power. In short, we weren’t satisfied with doing the same ol’ same.

In North American English, wrench is the standard term. The most common shapes are called open-end wrench and box-end wrench. In American English, spanner refers to a specialised wrench with a series of pins or tabs around the circumference. (These pins or tabs fit into the holes or notches cut into the object to be turned.) In American commerce, such a wrench may be called a spanner wrench to distinguish it from the British sense of spanner.
When it comes to specific jobs, you can find wrenches to help you complete them. Torque wrenches, strap wrenches and pipe wrenches let you get the perfect amount of force without overtightening. Without the right wrench for the job, you risk stripping the bolts and damaging your work in progress. Ratcheting wrenches are perfect for getting jobs done quickly. Many will often feature a standard crescent wrench end in combination with the ratchet, effectively doubling the number of wrenches you have.

Box-end wrenches have ends that enclose the nut and have 6, 8, 12, or 16 points inside the head. A wrench with 12 points is used on either a hexagonal or a square nut; the 8- and 16-point wrenches are used on square members. Because the sides of the box are thin, these wrenches are suitable for turning nuts that are hard to reach with an open-end wrench.

crow's-foot spanner A wrench that is used for gripping the nuts on the ends of tubes. It is similar to a box-end wrench but, instead of encircling the nut completely, it has a narrow opening just wide enough to allow the wrench to fit over the tube, and thick jaws to increase the contact area with the nut. This allows for maximum contact on plumbing nuts, which are typically softer metals and therefore more prone to damage from open-ended wrenches. common

clamp ratchet wrench clamp ratchet spanner An open-ended multi-size ratchet wrench. The ratcheting mechanism allows the nut to be clamped-on or loosened with a reciprocating motion; flip the wrench to change direction of the drive. The wrench takes the advantage of the clamp action to allow multiple sizes in both SAE and metric standards. Each wrench typically will allow up to 3 non-metric sizes and 3 metric sizes. adjustable


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
Agonizing; extremely distressing, unpleasant, or emotionally disturbing; having a severe effect on one's feelings. What a gut-wrenching loss for the young athlete, who poured her heart and soul into this match. Kids today are so desensitized that images of violence their grandparents would have found gut-wrenching now barely even register a response.
If you find yourself working with automotive equipment (click here for cordless impact drivers or see these brushless impact drivers) or on mechanical based projects quite often, you likely know the benefits of having the best cordless impact wrench available on today’s market. Having such a pristine tool helps to make work an easier process and allows you to go about your day to day tasks with ease. You’ve probably been at the point in life before where you’ve had to settle for tools that were second best.
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.
One issue noticed by a couple of the testers was the placement of the reversing switch. The switch seems to be right in the path of your trigger finger. Sometimes, when trying to go fast, the forefinger would push the switch into the neutral/locked position. This didn’t happen all the time, and it seemed to only be noticeable to those with larger hands.

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.
We’ve all been there. Using the basic tool models can be frustrating – especially when you know that you could be using a tool that would cut down your working hours into a fraction of what it used to be – but thanks to modern technology it’s no longer an issue. Because of rapid advancements that are being made in the technological field, you’ll be able to afford some of the best tools that equipment and machinery manufacturers have to offer and stay on top of your workload.
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.
