Used to have cheapo 12v hitachi. Its poor little clutch didn’t fair well when I asked it to drive several 5 inch lags.
DeWalt what I use now. Received a 6ish tool kit as a present a while back. They all get light use but the sawzall is certainly the most used. Diablos 3tpi blade makes for a great and violent pruner.
No more cheap bits though. Driver or drill. (Sockets too.)The level of annoyed and frustrated cheap bits makes for just isn’t worth it. Drivers hold better, strip less, and last longer. Drills go through material faster, break less, hold an edge longer.
