Update: June 24, 2017 – 1 year later. I’ve used this gun a lot in the past year and I swear it’s just as powerful as the day I got it. I will say the only negative about this tool is the button to switch directions is too close to the trigger and sometimes I accidently hit and turn the nut the wrong way. But that’s it. The rest of this tool is perfect.
Most of the last 37 years in auto repair I’ve used Ingersol-Rand impact guns. A few years back I bought an 18-volt cordless impact from Matco Tools. It was very impressive. And very expensive. After about a year and a half, I had to have it rebuilt.
Recently I got a new Dewalt 20-volt 1/2 impact wrench. Oh. My. God. It’s amazing how powerful it is. And since it’s brushless, hopefully, it will last a long time before having to be replaced. But even if I have to buy a new gun every year or so it will be worth it since it’s over 50 percent less cost than the 18v Matco gun I first bought. Plus, the Dewalt gun is shorter and easier to get into tight places. And the most powerful impact wrench I’ve ever used.
