Like Butter!
Rating: 5
This drill makes holes in concrete like butter ( just make sure you hold it straight, and don't hit any re-bar!). I put 15 holes through 8 inches of concrete in a matter of minutes, just make sure you tighten the auxiliary handle well or the tool will spin on you! Comes with a large case that holes extra drills, and a really long cord (~ 10 ft.). The variable speed is handy as well as the hammer only mode ( I would also like a drill only mode as well a a reversing switch). Fine tool although the cardboard shipping box could be more robust and some foam inside the case to keep the tool from sliding around during transport.

I just used my Bosch 850 hammer drill for the first time taking out 16 SF of concrete to lower a shower floor. It helped do the job performing much better than I could imagine. I love this hammer drill.

Nice upgrade
Rating: 5
This drill is replacing a Bosch11240 that has drilled a lot of anchor holes over the last 9 years so when it came to getting another drill it was going to be a Bosch. We gave the new one the workout this weekend anchoring down tracks and this drill did not dissapoint and is much more comfortible to use, nice tool.

Reliable Rugged Tool

We have three of these hammers in use and they get put through paces every day. These hammers take a beating with very little down time or repair. Definitely worth the money.

Great Bosch Hammer
Rating: 4
Great tool , use this almost every day for a few hours. i did have a issue with the fan making contact with the baffle and it melted together and seized the tool. took it in for warranty. a few days later got it back and it has not failed since. and that dates back almost 2 years. Very happy customer.!

Good Hammer Drill For The Price
Rating: 4
I use this primarily for light demo on concrete. This tool works well for chipping and removal of concrete around stub ups. It is light enough where it won't wear you out after 10 minutes of hammering. Good tool at a great price.

I am now on my second DCD991 hammerdrill/driver. I just purchas the bare tool because I have multiple 9ah batteries in my toolkit. This drill is a workhorse. I use it daily. Mostly for drilling holes through steel, concrete/brick and in a very oily, dirty environment. This drill holds up to all the obstacles thrown at it. I have never had a problem. I recommend the flexvolt 9ah batteries, the lanyard and belt clip.

Very Durable
Rating: 5
I have had almost every name brand high end drill out there over the years and this one has been the best hands down. The power is untouchable by any other I've used. It's been extremely durable and with the 5ah XR battery it last all day and can drive large deck and framing screws without even a hint slowing down. Best drill I have ever owned. Definitely recommend DeWalt 20v XR drills. [This review was collected as part of a promotion.]

No Nonsense Brushless American Drill
Rating: 5
I scored this drill new for a song and it's held up great. Don't waste your money on the hammer version - if you actually need to punch a hole in concrete SDS+ is the way to go. This drill also has a very nice light (same feature I later found on my Mac Tools (DeWalt) 20v 1/2 High Torque Impact) except here you get different duration of spotlight, as opposed to torque settings. Also, the lower "2nd" speed is nice, I wish my DCD777 had a range between 1st and 2nd for times when you're drilling smaller holes in softer metals and can pick up the pace a bit. 10/10 overall, very pleased. Hopefully I can get quite a few more years out of it.

Great drill for home and work
Rating: 5
I bought this drill about 5 years ago. It still runs today like it did when I pulled it out of the box. I went with Dewalt because my uncle bought a combo set of Dewalt drill, impact, circular saw, and reciprocating saw 15 plus years ago and still uses them today. Even after all the heavy use and abuse they have endured it amazes me that they still perform. [This review was collected as part of a promotion.]

Good machine worth every penny
Rating: 5
I've had my drill for a while now maybe going on three yrs I've lost track. It is rugged easy to use and powerful. Im not a big fan of the electronic clutch but it does its job. I prefer the old still clutch. Im sure this clutch is designed so you don't burn out the motor but it can be annoying when driving larger lag bolts. All I hope is that dewalt stops redesigning their batteries, I'm getting tired of buying adapters just to use my older tools. I do recommend this drill it's built to last I've dropped mine from roof tops and it has never failed not even a crack and barely even scratched it; not recommended but nice to know it will hold up.
