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.

First job: worked like a dream!!

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.

Absolutely Love it
Rating: 5
I bought this for small shop projects, and it has performed excellent. The ToughSystem Case is just amazing, and I love the storage. I can have everything I need in one kit! Variable speed on the impact driver is just amazing, and the drill works so well. Although I have had a few problems with the driver's trigger sticking, that is only when I pull it at a weird angle, and is easily fixed by a quick grip adjust.

Best Brushless Drill I have ever owned
Rating: 5
I have had my drill about a year and a half, and I have only charged one of the two battery once they hold a charge like no other. I will not own any other than a DeWalt [This review was collected as part of a promotion.]

The new workhorse!
Rating: 5
Bought this as I thought my 18 volt XR drill/driver was going bad. Used it a few times to make sure it worked well. It did. Bought the 18 volt to 20 volt battery adaptor versus buying new 18 volt batteries and found the 18 volt XR drill/driver is still working fine,the 18 volt batteries were just getting weak. This new daddy will stay in its case a while longer as the 18 volt unit is running like a fine watch now with its 20 volt 5 AH battery.

Simply, Put Outstanding!

The battery life is second to none. I can do much work between charges. It has plenty of turning power for any purpose, and the three-speed transmission is a great extra to control speed. I bought mine with several matching accessories and I find them all useful.

Bought this about 2 months ago! And it’s amazing. Works fast and easy, no fuzz. Drilling holes in large wood beams was a breeze and the speed was unexpected. Great tool great battery time. FYI bought one as a gift for my father as well! Loves it. [This review was collected as part of a promotion.]

I have had my drill for some time & also another competitors drill, I always go back to "yellow jacket" as it sting can not be beat! Even with heavy daily workloads the drill & battery out perform any other drill/battery that I've had. I will always choose dewalt! [This review was collected as part of a promotion.]

Amazing product

We use dewalt products at work and they’re amazing. I needed a good drill/driver for home use and I knew that dewalt would provide a quality product. I couldn’t be happier. Tons of power and great battery life. [This review was collected as part of a promotion.]

Was waiting a little before writing this. I have been using them for a little over a year, these replaced my Milwaukee. Highly recommend. They are tough and the batteries last long [This review was collected as part of a promotion.]
