I've got the Bosch 18v stuff and it's awesome. My new 18v sds ec is class, the battery lasts all day and it's extremely light and packs a punch. It's can do everything from concrete block to rebar concrete. I also have an 18v Impact driver and that's a nice bit of kit, it will drive 5" 10s all day. Last but not least is the 18v robustaseries combi drill. This is a tank it does 6" holesaws without wincing and will drill 32mm 600mm augers aswell. Hilti is nice but a bit too expensive. Go for 4ah battery as they last all day
