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.]

Perfect drill
Rating: 5
I've owned a dewalt still for 10 years and finally decided to upgrade. What a great investment. Can't wait to use this new drill for another decade. [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.
