Did the job
Didn't have the torque of my full size but I needed one shorter to get into tighter spaces on vehicles where even a breaker bar won't swing. Did the job. Just took a little bit longer. The price was right too.

Brute Force in a compact package
I genuinely appreciate the compact size and impressive power of this tool. With the 1/2x1/4 impact adapter, I can easily use it as a nut driver for both lag screws and smaller screws, utilizing the 1/4 bits from my nut driver set. Additionally, the versatility of this tool allows me to remove the adapter and seamlessly switch to my 1/2 drive impact sockets. This capability ensures that I can efficiently remove and tighten the lug bolts on all my vehicles, always meeting the required specifications. The best part is that I no longer need to deal with cumbersome air hoses, making my work much more convenient and streamlined.

Most incredible Impact Wrench!
My first Dewalt Impact was 10 years ago. A 1/4 model. Powerful and capable of most projects. I wanted a tool that could remove lug nuts and other automotive task that were difficult, particularly with removing frozen nuts or bolts. This tool has removed everything that I have come across. It is a must have tool in your garage. It is a game changer!

Loud for lugnuts
Worked ok. Strong enough for lug nuts but still took some time on each one. The Impact driver can do almost as well as this can and can be used in more applications

Lots of power packed into this little impact driver. I have always been a fan of DeWalt tools. I was skeptical of how well it would do the job of removing lug nuts. I had to change tires over from summer to winter and set out to see if it was up to the challenge. This little impact didn't miss a beat. I did 6 different sets of tires on 6 different cars, trucks, and SUVs, not all mine. I did my 2017 Toyota Tacoma, my neighbor's 2025 VW Tiguan, and 2022 Toyota RAV. No problem until after the 6th car, the battery started to get weak. Put on a newly charged battery and back in business. Love this great little impact driver. I will be throwing it in the truck from now on whenever I go on longer road trips. If your on the fence weather it can do the job, believe me it works great. Great product for a great price.

Al principio no contaba con batería para ponerlo a funcionar ya que adquirir las baterías superó mis espectativas al utilizarlo para retirar birlos y tornillos con demasiado torque
