Rated 4.4 out of 5 by 63 reviewers.
Rated 5.0 out of 5.0 by Great $100 drill for small jobs I have two Dewalt DW511 hammer drills.I got this one on sale for $80 at the HD in Melbourne,FL.I am a contractor and I use it mostly for drilling 5/32" and 3/16" holes through concrete slabs ,bricks and block walls (5-10 holes or so at a time) for installing tap cons to anchor wood studs.This drill is great for this task.Occasionally I have used it for drilling up to 1/2" holes through concrete and it did well,but I took my time.It is a small drill and has it's limitations.It's not my $500 Bosch combination hammer drill ,which can drill 1/2" and up holes in concrete slabs all day,quickly without breaking a sweat.All in all,the Dewalt DW511 is a great inexpensive hammer drill for small jobs.If you are looking to drill many 1/2" or larger holes into hard concrete slabs quickly,you will burn this hammer drill out quickly.It is not made for that.Use the right tool for the job.

Rated 4.0 out of 5.0 by Right tool for the right job I needed to drill some holes in a concrete slab, so did a little research. This particular Dewalt VSR hammer drill got excellent reviews, and I've rarely gone wrong by following them, so I bought one. The first hole took forever and the bit was completely trashed, so I took the bit back. Turns out it was the wrong kind for what I was doing (guess I should have asked for help...), and the HD employee helped me get the right one. I took that one home and finished all the holes in about 20 minutes! The drill itself performed perfectly, although it did get quite hot....hence the 4 stars instead of 5. May 20, 2014
Rated 5.0 out of 5.0 by This thing ROCKS I had purchased another hammer drill from Home Depot (Ryobi) and went through two of them before realizing they were junk. Took me forever to drill 1 1/2" into a slab in my basement. Almost as if I was hitting rebar, but there was no way I was hitting rebar in every hole I was drilling. The chuck fell off the first one, so I got a replacement. The second one, after 2 hours of use, was so hot, the drill/hammer switch melted and fell off, and the actual switch in the drill melted and resolidified itself locked in hammer mode. I returned the second one and bought this Dewalt Hammer Drill. NIGHT AND DAY! I can drill 6 holes in the time it took me to drill one with the Ryobi - using the bit I took out of my Ryobi I had returned. Very lightweight, but very powerful. It's a shame to think of all the time I wasted not having this drill for the 300+ holes I had to do. March 17, 2012
Rated 5.0 out of 5.0 by Amazing Want to drill into a brick wall? I did, and my Black & Decker 18V cordless was not up to the task. I initially thought I may have been using the wrong anchors, but after research I picked this drill up. The subsequent job, while before was pretty tough, was LAUGHABLY SIMPLE with this drill. I literally laughed like a mad scientist as I pre-drilled and drove 1-1/2" long screws into 80 year old masonry in seconds. If you're reading this, then this is the drill you need. Period. Would have paid $150 for this. December 1, 2013
Rated 2.0 out of 5.0 by Had to take it in for repair after first use Purchased this hammer drill knowing that I would need it in the near future. 4 months later, started a bathroom renovation and used the drill for the first time. Used the hammer drill setting to drill some holes in concrete, but noticed it got hot really fast. After drilling 3 holes and allowing the drill to cool, I started on the fourth hole and grease started shooting out from the sides and chuck area. Bought this corded hammer drill thinking it was stronger and built to last, especially with the Dewalt name backing it up, but was severely disappointed. Fortunately, it's covered under warranty, but I sure didn't expect to have to use the warranty after it's initial use. March 7, 2013
Rated 4.0 out of 5.0 by Good purchase good price and product. worked fine on drilling into concrete and brick. October 13, 2015
Rated 5.0 out of 5.0 by Great, powerful, multi-function drill. Bought this drill to supplement by cordless drills for when I need additional power, or need the hammer drill function. Drill works great and gives the user the ability to choose drill or hammer (as I am sure most do). I have used this drill almost daily for about 6 months now, and no problems. You need to make sure you are using the correct bit for the job you are doing. Great value for the features and warranty March 27, 2012
Rated 5.0 out of 5.0 by The tool for the job If you need to drill holes in brick or concrete - do yourself a favor and buy this drill. Even if you have only a few holes to drill - for attaching a hose reel to the outside of the house in brick, or attaching the transformer boxes for exterior lighting, putting up shelving in the basement attached to the concrete - this drill will make the jobs go quick. Get earplugs, however, because the hammering function makes a lot of high pitched noise. Oh, and it also switches to a regular drill as well. May 4, 2011
