As drills go, it's fine. If, however, you want a hammer drill, this isn't it. Because it's a regular drill with a hammer function, it spins WAY too fast for hammer drilling and also doesn't produce enough hammer force. If want want that, you should definite get a proper SDS-plus rotary hammer. Several are available for not a lot more than this and will do a great job of drilling through concrete. This drill is just going to burn up bits.
