To get back to your original question and out of the weeds, the m18 series will do most of what you described. The only issue I have with them (this includes all the drill/hammer drill combo) is that when you do want it to drill concrete they are too fast and burn up the bits as fast. Sure you can feather the trigger but most people don't and tend to put the drill into high range to "cut faster". For that reason, while I have a few of that type, I also have a stand alone sds max hammer drill. But if you are not going to be coring or needing to drill a bunch of holes at once into concrete then the m18 will suffice. Milwaukee used to use Panasonic batteries in their packs (not sure they still do) and those were always among the best rechargeable. The brushless motors stand up to much more abuse, including getting wet, dropped in mud and in reality have a bit longer service life. As stated earlier in this thread, the drill bits make the biggest difference and using some cutting oil when dealing with metal, but from the sounds of it, you know that already.
