This is the way.

The impact wrench I'm looking at is one of the newer lineup from DeWalt. I have DeWalt everything already (impact driver, hammer drill, circular saw, reciprocating saw... Even my hedge trimmer, string trimmer, lawnmower and snowblower), all using the 20v MAX or compatible batteries, except the snowblower, which uses the power flex 60v (which can be used in 20v tools, but 20v MAX batteries cannot be used in it). The impact wrench uses the same 20v batteries. So I just need the tool. It's still something like $200 for it, but I don't think I'll need anything more for power tools for a long assed time after that.

We picked most of this stuff up over the past year starting with a kit (impact driver, hammer drill, circular/reciprocating saws, even a small light, with some batteries and a few extras) about a year and a half ago, and we've been steadily adding to it. I chose DeWalt because I have an old, 12v drill I used for like 10 years and it still works. The original battery has left us but the second battery I bought when it was new (it came with one and I bought an extra so I could have one in the drill while one was charging) is still kicking. I got a replacement for the original battery that shipped with it, so I still have two for that unit. It still works, and it's fine, but there were a few times I really needed a hammer drill and the puny 12v was all that I had... But that was literally my only real gripe about it. Given that history, I wanted to keep with DeWalt because they clearly make tools that can last.

I wanted to go with one brand so I didn't require several different battery chargers for different tools. DeWalt was only missing a snowblower, but they released one late last year and we obtained it shortly after it hit the market, which completed our large tools. There's only a small number of handheld tools in the DeWalt lineup that I still want to get. The impact wrench is one. Another is a brad nailer (IIRC), because I have to install some baseboards/trim, but it's hard to justify buying a $500+ tool for the job.

My entire automotive kit probably needs to be replaced. I have a complete socket set with ratcheting wrenches, and not a whole lot besides that at the moment. I will need to get a new torque wrench, breaker bar... Probably a lot more that I'm not thinking about right now. I have access to my brother's Jack and Jack stands, so I'm ok there. For the impact wrench, I'll need to add a small set of impact ready sockets for it, otherwise I'm going to rip my sockets to shreds.

I have a ton of electrical testing stuff for my other hobbies, so I'm good on that front, but I notably don't have a CCA tester, which I would like to get. Among my more electronic things I have a fairly crappy, and old, OBD2 reader, which has come in handy plenty of times.

As you can imagine, I'm the "handy" guy in the family. I just find it all fascinating, but I wouldn't want to make it my job. After working on a vehicle for a few days, I don't even want to look at a wrench for several weeks.

By day, I work in IT, so I'm generally sat at a computer pushing buttons until the screen dots show up in the right order.
