When I installed car stereos for a living in the 80s and 90s, 12 and 14 volt Makita cordless drills were essential. Expensive, but also powerful, with a lot of "feel" so you didn't strip the customer's expensive dashboard etc. they were $300 or more each back then, made in Japan.
When the 14V finally died about 10 yrs ago, I made do without anything cordless, but one B+D hammer drill with a half inch metal chuck for years....and hated using it........but...no dough, kid, etc.
About 5 yrs ago, I bought a used set of Porter Cable cordless 12V and 18V drills, impact drivers, multiple batteries and chargers from a car club member (a contractor) for $200.
12V: 2 chargers, 4 batteries, 2 drills and 2 impact drivers
18V: 2 chargers, 4 batteries, 2 drills and 2 impact drivers
Have since added a recipro saw, 1/2" hammer drill and 1/2" reg drill, 7-14" circular saw and a flashlight along with 6 more batteries. Everything when it was on sale / clearance.
The 18V batteries were at Lowe's for $10/pr
instead of $100. I bought both sets they had.
I really like having small versatile cordless tools, they are invaluable for working on cars, especially interiors. I also have about 30 air tools and a whole bunch of corded sanders, routers, saws etc. It is a luxury to have them all, but every job calls for the right tool.
I know a couple of friends who swear by the DeWalt 20V impact guns - one charge allows you to change 4 wheels at the race track twice, and it is half the weight of my $400 air impact gun. But it also cost $450 and doesn't have the power when things get real tight.
All of this is designed to give you some food for thought, perhaps a used decent set of cordless will get you into that game, worst case is having to buy some batteries. I know I despise lugging cords and heavy tools around.....almost as much as having to deal with ****ty old batteries that don't hold a charge long or cycle out early lol.
I dumped 3 batteries this week, so I'm down to 11 now; but I also like having dedicated tools loaded with the proper ends - one impact with a counter sink, one with a 1/4" drive socket, one drill preloaded with a commonly used drill bit. I do the same with my dozen air tools when I'm fabricating metal - so nice to have 4 die grinders all loaded ready to go. At $10 or $15 each at HF, it is not a luxury, but rather a solution to a problem most people don't realize they have lol.
Once you commit to a cordless system it makes more sense. I would never do without small and large cordless tools tho. The 12V drills and impact drivers are so tiny and useful......and way easier to handle, especially overhead or in tight ugly places. With cobalt drill bits, they perform way beyond expectations.
Good luck with your search and purchases.
