Will not be disappointed
Rating: 5
Have 2 of these (4 compacts as well) in the shop. One is 6 years old and the other is 5 years old. Have been used indoor, outdoor, hot temps and freezing temps. In a manufacturing setting as well as on the mining job sites they've never let us down. Very happy with these drills and the abuse they take. [This review was collected as part of a promotion.]

I've owned this drill for about 8 years now. Never had a problem. Even when dropping it off a ladder or using in the rain. Very dependable. [This review was collected as part of a promotion.]

I use this drill at work 10 plus hours a day, and also have one at home, this is the very best drill/driver I've ever had, and hopefully ever need, scooping up another one as we speak for back up. [This review was collected as part of a promotion.]

Can't beat for price
Rating: 5
Nothing will beat a corded hammer drill but this Dewalt, for price paid, is just about all you need. It's three speed and and all metal chuck are a nice change from the (becoming more common) plastic chucks. It provides power when needed (coupled with the 8AH battery) and can take a good beating. I am not a professional but do use my Dewalt drills for a lot of around the house and "can you help me with this" tasks. The drill is on the heavier side but is not a complaint from me for price paid and product given. Would buy again! [This review was collected as part of a promotion.]

This hammer drill impressed me the first time I used it. Still does a year later. I absolutely love this drill. All the power you need to get through the toughest of jobs.

Best hammer drill on the market period.
Rating: 5
I’ve owned several brands of power tools and dewalt is by far the best one out there. My tools are my money makers and nothing even comes close to the quality and dependability of dewalt. They’ve been left out in the rain, frozen solid, fallen off roofs and out of scissor lifts, dropped in puddles of mud and in the dirt and they still come to life every time I pull the trigger. Don’t settle for anything else. Buy the best, buy dewalt [This review was collected as part of a promotion.]

Last drill you will ever need!
Rating: 5
Very satisfied with all my 20v tools. I use this my drill almost everyday and even though it no longer looks pretty, the performance is! Never really had a dewalt tool I wasn’t satisfied with. I’m not a brand loyal type of guy but when I’m ever in doubt, or choosing between brands I’ll go with dewalt. There comes a point in time when you realize it’s not worth it to cheap out....

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.
