Great drill except
Rating: 5
Bought my drill just less than 2yrs ago. Been a great drill until 1 day used it in hammer mode and now its stuck in hammer mode no matter where you set to. Dewalt is sending a label for it to be shipped to a service center to be checked and repaired or replaced I suppose. I have really liked this drill. Hope all ends well

Great, Powerful Tool. Solid Metal Chuck Collar
Rating: 5
I've had this hammer drill for just about a month. I'm not a construction worker who uses this every day, but I'm a facility manager who uses is occasionally. I didn't want the regular drill/driver, because I do need to occasionally drill into concrete. I needed the hammer drill. I looked online, and also went into the store to look at them in person. I advise you to know what you want, because there are a few models of Dewalt hammer drill. I saw some that had a plastic chuck collar, and just looked and felt cheaper. I saw this one with the metal chuck collar. It's a much more solid tool, and even feels more solid in your hand. Sure, it's a little heavier, but if you're using the hammer drill function, that's what you want. After all, if you didn't need a hammer drill, you would just get a regular drill/driver. I wouldn't trust that plastic chuck collar to hold up well in the hammer function, which is why I specifically got this model with metal chuck. It took some more work to find this one and order it, but it was worth it. I've used it to drill concrete, and for regular drilling. If you're working overhead, yeah it's a bit heavy, but I'll take that trade-off to have a solid tool that will last. One last word; I didn't think I would need the Tool Connect feature, but I do manage two different properties, and it has come in handy to be able to track the tool.

Will Always use Dewalt
Rating: 5
I have had this drill going on three years now and it is still going strong. I work in construction an often need to go hammer drilling to hand equipment in places that can be difficult to reach with a corded drill. This drill has never let me down. The power and drive this drill delivers often outlasts and outperforms other brands. My friends who use Milwaukee offer come burrow my Dewalt when they need the job done and their drill won't cut it. About a year ago I lent my drill to someone who misused it. The damaged the chuck prints badly and it no longer was able to sustain its grip on any bits. I took it to a Dewalt service center in Carrollton, TX with my receipt and they took care of the repair for free under warranty. Staff were friendly, respectful, understanding, and polite. They repaired the problem quickly and it has worked great since. [This review was collected as part of a promotion.]

A Beast of a Drill
Rating: 5
Bought this drill about a year ago and have put it through its paces nearly daily. Everyday it does what I need and then some out preforming every other drill I have and all of my friends drills. Moment I first put a battery on it and let it go I knew I was in for a treat and I was right. Haven't found a single thing it struggles with. And thanks to the Bluetooth I'm not worried at all about it going missing. Wish I had more tools as reliable as it. [This review was collected as part of a promotion.]

I love my 20v Dewalt cordless drill
Rating: 5
It has held up very well and the 20v lithium ion batteries are light and powerful. The drill clutch is still going strong after months of use drilling plate steel, sheet metal, plastics and lots and lots of wood. [This review was collected as part of a promotion.]

Great Drill!
Rating: 5
I have owned this drill for about 8 months now. I have absolutely no complaints, although I will say if you plan to do some serious work with this, pick up a few 5 or 6 amp hour batteries. This drill chews through the batteries provided in the kit pretty quick. I have found this tool capable of doing everything I've put it through. I'm not a contractor of any sort, but I'm an avid DIYer and handyman-on-the-side, so this tool has seen some serious use. Haven't found anything it can't drill through quickly and efficiently when using the proper bit, and it's light enough even with a 5 amp hour battery attached that I don't get fatigued. The built in LED lights are great, they adequately light up the project and I've rarely found that my hand or the workpiece gets in the way. I have not used the Toolconnect feature, but if it performs like the rest of this drill, I have no doubt it would also exceed my expectations. [This review was collected as part of a promotion.]

This drill has done everything I put it through with ease. Whether it's drilling pilot holes in glass tile or installing lag bolts with the hammer feature ! Great drill! [This review was collected as part of a promotion.]

great light
Rating: 5
I bought this drill a little over 2 years ago befor I started college. In that 2 years between job sites at school and summer work, its been worked real hard, droped dozens of times, been rained on and so on, and the drill still works just like new. I've used this drill from rough framing to boring holes in the cabinet shop and if I could do it again I would buy this drill. takes a beating, isn't too heavy, plenty of power and the battery is the best I've ever had.

Battery failure - a second time
Rating: 3
I bought this drill last week but had to return the first one since one of the batteries refused to charge. My second one had the same issue. I kept this one on the assumption dewalt would call me and make it right. I have emailed, waited on hold, and now writing this review. Perhaps someone, just one, will call or email me And allow me to exchange the battery and make this right.

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.]

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.]

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....
