Bought this drill to replace my old workhorse, which was a 1984 AEG hammer drill- which by the way, is part for part, exactly the same drill. Even takes my old right angle adapter. I have used this drill for extensive concrete work for residential construction. When installing almost 100 circuits in a residence, with the right angle adapter, for the wire runs, I could quickly and easily drill 2" holes, 3" from the top of the joist and 3" from the support wall, in 2x10's on 12" spacing. I'm now relying more on the M18 Concrete drill, but when I need the power, and AC is available, this is my goto concrete and big hole drill. Great for mixing drywall mud and all types of concrete anchor dilling. BTW, if you use GRK Caliburn concrete screws, wich you can screw in or out numerous times, and still leave a concrete hole that remains good and solid, you'll never touch a Tapcon again. This drill and GRK Caliburn concrete screws - are a match made in heaven.
