DeWalt Atomic 20V Max impact wrench review

DeWalt Atomic Impact Wrench squeezes solid muscles in a tight space

It’s the ubiquitous dilemma for impact wrenches – how to get more torque in a confined space. The DeWalt Atomic 20V Max Impact Wrench aims to solve this problem once and for all.



DeWalt Atomic 20V Max impact wrench: Compact performance

At first glance, it is clear that DeWalt designed this impact wrench as a compact model. It is less than 5 inches long from tip to tail (4.97 inches). At the top of the handle, the head is tilted slightly upwards, so you have more space without the battery getting in the way.

The tool is also relatively light. It only weighs 2.5 pounds, a 2.0 Ah battery comes in at 3.3 pounds, and a 5.0 Ah pack weighs 3.9 pounds.

Although it is compact, the brushless motor brings some muscle power. It achieves a torque of 450 ft-lbs nut locking torque and 300 ft-lbs fastening torque. This combined with 2500 rpm and 3550 IPM for your screw removal pleasure.

This is strong and we compared it to cordless and pneumatic options to see where it really fits. Milwaukee’s M18 Fuel 2855 sets an impressive standard for compact 18v impact wrenches, but at 250 ft-lbs, it’s not as strong at both tightening and cracking nuts.

Looking for an Ingersoll-Rand pneumatic benchmark, the ultra-compact 36QMax is capable of 640 ft-lbs for breakaway torque and 360 ft-lbs for attachment.

At the moment, the DeWalt Atomic 20V Max Impact Wrench leads the cordless category in terms of strength, but there are even more powerful pneumatic options.

Instead of just taking DeWalt’s word for it, we decided to give the Atomic Impact Wrench a try. We adjusted the torque on our rig to different levels and found that this model could consistently remove 450 ft-lbs with a 5.0 Ah battery. We even broke bolts up to 461 ft-lbs.

LED lights

We LOVE the LED lights on these wrenches. Three lights surround the drive and there are controls to turn them off or to choose between two intensity modes. If you’re sniffing around on an engine they are great!
