Across the board, the Bosch HTH181 wins for being the most ergonomic, and this was almost unanimous from our users. Milwaukee’s Gen2 (2767) and Ingersoll Rand’s W7150 tied for second in ergonomics. The Ingersoll Rand is also the lightest of the bunch, weighing just 6.88 pounds with the 5.0 Ah battery. Bosch and DeWALT followed in a close 2nd and 3rd, at only 7.04 and 7.10 pounds, respectively. The heaviest tool in the batch is the Matco Tools at 8.02 pounds, with the 4.0 Ah battery.

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.

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.
When choosing your new cordless impact wrench, there are a few things you should consider. The first thing to decide is the brand. If you have other cordless tools, it’s a good idea to choose a cordless impact wrench that uses the same battery pack and charger as your other devices. It’s also a good idea to spend a little time doing a cordless impact wrench comparison. Some of the high-end models offer additional features such as adjustable torque settings, which cuts out the need to use a manual torque wrench.
Grip – Impact wrenches can actually come in a few shapes and sizes, but in this guide we’ve concentrated on models that – if you squint – look like standard power drills. We’ve done this as most cordless style impact wrenches are of this type. They are also simple to use. Because of their shape they do need a good grip, so make sure you bear that in mind. A good grip should be ergonomic, so it’s comfortable to hold, with good trigger placement and a raised or rubberized surface so you can orient the tool in your hand by touch only.

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.
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.
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.

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.
The Ryobi P261 is a great tool for contractors and one of the best investments you could choose to make.
