What can I say, Wow, this thing does fast holes compaired to the Harbor Freight drill I had been using. I had a $60 SDS hammer drill from HF that I had been using for about 6 years, and it finally gave up the ghost. I purchased this drill because of the handle design and the features it had were about the same as the old drill and I was very comfortable with using it. I could not beleive how much faster this drill was poking a hole in the concrete than the last drill. For a hammer drill, I think this is fairly light weight, but the construction is very solid and feels like I will be getting a good long life out of it. I love the fact that to put a bit in, you don't need to pull the release collar back, you just insert the bit. So far, there is nothing to say bad about this drill, and I hope it continues to be as good as it has been. I love this drill!
