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.

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.


Look for design enhancements, such as all-metal construction for the gear housing or high-strength plastic overmolds, which helps to prevent damage due to impacts or being dropped. Impact wrenches with brushless motors have fewer moving parts, which means that there’s less of a chance of components breaking down, and maintenance is easier to perform.

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.

And if the lug nut is in a position that is frequently exposed to the elements – especially water – you’ll have to take into consideration the possibility that your lug nut could quite possibly rust over and cause some major problems for you. In any of the above situations, you’re going to need a lot more torque power to get the lug nut out than it took to put it in originally.
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.
Leading the pack in driving the weight up the scale is the Milwaukee 2767 (Gen 2) cordless impact wrench. While all the others can’t max the scale with 50-pounds atop, the 2767 can. In fact, we had to add 10 more pounds, a total of 60, and the Milwaukee 2767 still drove it the majority of the way. DeWALT and the Ingersoll Rand followed a pretty close second at 94% and 92% of the Milwaukee in the power category.
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).
Look for design enhancements, such as all-metal construction for the gear housing or high-strength plastic overmolds, which helps to prevent damage due to impacts or being dropped. Impact wrenches with brushless motors have fewer moving parts, which means that there’s less of a chance of components breaking down, and maintenance is easier to perform.
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
Keep in mind that all rechargeable batteries slowly lose their charge when not in use, but some batteries lose their charge much faster than others. The capacity of a battery used in a power tool is usually expressed as the amount of amperage hours (Ah) that it can deliver. “Ah” is different than the overall amperage rating of the tool. Here, Ah represents how much energy flow the battery can hold, not the level of current during operation. Keep in mind that a higher Ah means longer battery use between charges.
This 2767 Gen 2 delivers the power and does it over and over, without a hiccup. Added features, such as the bolt removal mode, set apart the Milwaukee Gen 2 from the rest. Earning 97.6 points from a possible 100, this second generation high torque impact from Milwaukee beat 2nd by more than 11 points. The added LED worklight, shining from the battery area onto the work surface is a nice feature as well. At only $449 and a 5-year warranty, this also makes it the best value as well.

As you plan to buy a cordless impact wrench, it’s important to understand that while it generates plenty of torque, it’s usually less than comparable devices that use compressed air. Because of this, a cordless impact wrench is an excellent option for smaller jobs. It’s ideal for a home workshop where space is at a premium. Because a cordless impact wrench uses rechargeable batteries, it can be a little heavier than the corded variety, but does offer much greater mobility, especially in areas too tight or remote to accommodate a power cord.

Makita cordless impact wrenches deliver high torque impact power and are designed to fit impact-rated socket sets. They pack plenty of torque for a wide range of fastening and loosening tasks, and are powerful and convenient substitutes for air-powered and AC wrenches. The batteries provide long run time and quick charging for less downtime and increased productivity.
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.

Summarizing a shootout always presents a problem. The real bottom line to this best cordless impact wrench shootout seems to hang solidly on power and performance. Milwaukee aimed to hit hard with the release of the 2767 high torque impact back in September. The results show their efforts seemed to have paid off. There’s been a ton of hype over this tool since the Milwaukee Tool NPS17 media event in Milwaukee, WI back in May. We had the privilege of getting our hands on the 2767 back then, and we couldn’t wait to bring it in the shop for testing.
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.

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.
