t. Cordless tools on the other hand are destined for obsolescence much sooner. I’ve got a nice 18v nicad DeWalt drill that’s probably only worth about $25. Back in the day it was $200+.
To some extent they’re the kind of tools you want to buy cheap, work hard and wear out.
I bought the Milwaukee 18V chainsaw when it was on a $299 'special purchase' deal that included an extra 12AH battery. Then I lucked into a one of the 1/2" drill & 6mm hex impact packages in well used condition with no batt or charger for $20!! $10 each ! 5 miles from the house ! They are beat up but work perfect. I may eventually buy more M18 yard tools when I see them cheap but the thing against them is they are HEAVY ! Heavy is bad when your neck , shoulders and back have seen better days. What's ironic is that I have used the Milwaukee chainsaw to cut down and clean up one tree but I have used the drill and impact quite a lot .
I have B&D 18V nicad tools of every description. I have a B&D 20v lithium 'cordless broom' blower that is very light and does ok for me. I have B&D 20v sanders. The cool thing I have is Ebay adaptors that let me use the B&D 20v batts in the 18v tools. I also made some adaptors that allow me to use the B&D 20v batts in other brands. This is the key to maximum usage.
You just have to monitor the batt condition yourself and STOP using the batt the second the rpm drops below full boogie.
I have a Milwaukee 12v NiCad 3/8" square drive impact from the 90s when I was doing dirt bike and ATV repair. You can buy batts off Ebay cheap and I made my own adaptor to use the B&D 20v.
I have a Milwaukee M12 lithium 3/8" square drive ratchet.
I have a Ryobi 18v One+ 1/2" square drive impact. Very stout on setting 3 , strong on setting 2 and equal to the somewhat weak 12v NiCad impact mentioned above. This tool has been the surprise of the whole lot. More power than my 120V late 70s American made 1/2" impact that it replaced. The other 2 settings make this tool usable in a lot more situations without worry of breaking things off.
So yes I hear you about only having one batt family to keep up with but you will be making a lot of compromises [ that you may not even be aware of
]. I like having the ideal tool for the job. Keeping up with multiple batts and chargers isn't that big a deal to me. There have been times during fab projects that I have had 5 or 6 or more drills, impacts, saws, etc spread around the work area. No changing bits or sockets
