Rated 3.6 out of 5 by 8 reviewers.
Rated 3.0 out of 5.0 by Poor Quality I initially bought this because the reputation of DeWalt. However, I'm very dispointed by the poor quality of this product. I bought this Hammerdrill to drill 1/2" with 3" deep hole on concrete. The chuck opened a few times on the first hole and it totally break down in the mid of the second hole drilling. I had to mail it back to home depot since I ordered it online. September 22, 2008
Rated 4.0 out of 5.0 by Works great I'v had my hammer drill for almost 2 years now and it still works great. Very powerful for its size and weight. The only complaint is the chuck sometimes opens up while drilling but not often enough to make it a big deal. February 21, 2007
