Bottom line, for the money, this is one of the best bang for your buck SDS Demo/hammer drill's you'll find. Puts out just .3 Jules of energy less than its cousin for half the price. Sure it's not as compact as the bottom motor mounted version, but it works nearly as fast and may have a better handle design(but that's mostly preference). The biggest nagging issue for me is storing in my tool box. Why can't they make this with a folding/removable handle? I have to remove the handle every time I put it away. I'd love to see one of these with a side folding handle.

Bought to use on a hard rock mining trip. Used in Dolomite all day long without an issue. When used with DeWalt 20 Volt batteries I could drill 8-12 5/8 holes 12 plus inches deep in Dolomite per battery. It had the power to hammer drill 24 inches into Dolomite which was very impressive. The shock reducing handle is effective in reducing fatigue due to the reduced intensity of impacts felt. Highly recommened.

I've had this drill for about a year and a half and have drilled a few holes in the hard rock around our house with impressive results. I had also purchased a bull point bit with the drill but hadn't given it much though. We have some small hard rocky outcrops in our driveway that I've worked on over the years trying to get rid of, but they are so difficult to break out that I stopped working on them. I was experimenting with the bull point on another project where I need to break up some rock and was amazed at how well it worked, so I tried it on the obnoxious rock in our driveway and was once again amazed at what I was able to accomplish. Before I knew it, I had a sizable pile of broken rock and a whole lot smoother driveway. This is not a big bad jackhammer, but if you're patient and efficient, you can do a lot of damage with this drill. I am able to work a couple of hours with a 6AH battery, and by the way, the Dewalt bull point is still as sharp as when I started using it. I am very satisfied with this hammer drill and would definitely recommend it.

This is the most powerful one that's not a pain in the ass to hold (there is one more powerful one but it's too heavy). If you want something like that just get a freaking jackhammer and build a house. Otherwise stick with this one it's a damn sight more practical and still packs a Very Heavy punch

Drilled thru 5" concrete driveway with easy. Need to use 5 amp battery for best results
