I thought it’d be great to have a cordless drill and one of those newfangled impact drivers, for a project. And it was SO great that I added a circular saw, a jigsaw, and a reciprocating saw (aka Sawsall). All are DeWalt 20V, as I’ve had great experiences with DeWalt corded tools, but it sounds like there are several great brands. Obviously once you start with one brand and series, you have a huge incentive to stick with just that one.
It’s a familiar story: you think you can get just one, and then you keep finding yourself buying again.
So, what else might it be good to get? Maybe one of those oscillating multitools that look so neat? A belt sander (I certainly use my corded one)? Are those goofy accessories like flashlights or blowers really useful, or are they truthfully just pandering to the overenthusiastic?
I gotta say, these things are great! I had a rechargeable drill and rechargeable power screwdriver years ago, and they didn’t work anywhere near as well as these do now, and besides, cordless tools back then didn’t always have replaceable and interchangeable batteries.
I do a variety of homeowner type things, have a small barn to maintain, various pressure treated lumber decks and walks, 1/8 mile of wooden stockade fence to maintain, etc etc. I need to install some HVAC equipment soon, we will need a kitchen remodel in a few years, et cetera. I’ve also found the reciprocating saw does great pruning (with the right blades of course) and have to think about outdoor tools too.
