What a great tool. This Dewalt Hammer Drill/Driver can pretty much drill through anything. Very much a work horse tool. It has more power w/Flexvolt batteries and is also compatible w/Dewalt 20 V MAX, heavy duty 1/2" ratcheting nitro carburized all metal chuck w/carbide inserts for superior bit gripping strength. The Led mode is 20 times brighter and gives more light in dark and confined spaces. The extended worktime with LED spotlight mode has a 20 sec. shut off for the extra time needed. This optimize tool has a 3 speed transmission and 11 torque settings. One thing I might add is this tool is very heavy so when first using play with the 3 speeds so you don't loose control of the drill. Another great product from Dewalt.

Perfect tool for any DIY household. My dad actually had this drill and I was tired of borrowing it from him. This Dewalt 20-volt hammer drill makes drilling into our brick and concrete home a breeze. We used this to hang shutters on our brick home, much much easier than my traditional drill. It’s the small things, I love the flashlight settings. The drill is not very heavy even with the battery. The arm makes it easy to apply pressure while drilling. Many different settings for every job imaginable. Dewalt is the gold standard in tools and I’m glad I picked up this drill. I was able to use my 20-volt battery from other Dewalt tools.

This DeWalt 20-volt max lithium ion cordless and brushless 1/2 inch hammer drill/driver with flex volt advantage is the tool only box. It doesn’t come with the battery or charger but it is a great compliment to your existing 20-volt tool set. The hammer drill has three speed settings, forward and reverse and clutch control. It comes with a removable handle as well as a belt clip. It also has an LED light control to help you see what you are working on.

This Dewalt 20V Max Brushless Hammer drill/driver is an absolute beast. I have the full compliment of Dewalt tools and this is an amazing addition to your arsenal. Have used it so far for typical drilling projects and it works comparable to my 996. I used it to drill some holes in some tree stumps and it appears to have some extra “juice” compared to the 996, but I really need a get a FLEXVOLT battery to put it to the test. Overall you won’t be disappointed, the quality is great. The side handle is great for certain projects and the light comes in handy when you need that extra bit of light to accurately complete a project.

The DEWALT 20-Volt MAX Lithium Ion Cordless Brushless 1/2 in. Hammer Drill/Driver with FLEXVOLT ADVANTAGE (Tool Only) is a beasty thing. It arrived well packaged and in excellent shape. It has a surprisingly long and easily removeable brace handle. One very needed feature, is the LED light, it has three settings, low, medium and bright that will stay on for 20 minutes. I don't know how many times that I have been crawlspaces long enough that my battery went dead on my flood-it light. Should that happen again, at least I will be able to see to get back out. Power wise, there are no complaints with 3 speed settings, 11 torque settings and it arrived just in time, my other hammer drill/driver is on it's last legs, getting worn out Good job guys, keep it up.

Dcd999 hammer drill
This thing is a beast, it's has a lot of tourque and power, it's not as powerful as the 998 but it's up there. The power range is in-between the 996 and 998, drilling in masonry is a breeze and using paddle bits and drill bits is buttery smooth. When it comes to size it's pretty much the same height and length as both the 998 and the 996. The weight on this is a little heavy but it's understandable because it uses a lot of metal parts, coming from using a brushed plastic drill which was way lighter. Overall it's a really solid drill, but we'll see how it holds up over the months, will update if anything changes.

    When I got home and open the box, the drill was a broken drill that somebody returned used and clearly scammed. Home Depot Home Depot failed to check the return item and restocked it on the shelf, which caused me to have to drive 20 miles back to the store and get it exchanged out.

        Stopped working after only a few uses
        I use my impact 98 percent of the time. So when I use this tool I expect it to work and function properly. But unfortunately it just stopped working. This and a light are the only tools I’ve ever had issues with. After investing money on your tools and this happens make you reconsider changing brands

          Not very durable
          I only got to use this drill a few times. All my tools are Dewalt and so far they’ve been good but lately I’ve had to return a few Dewalt tools I’ve bought. This drill is passed the one year warranty and I got to use it a handful of times only. Now I’m considering completely changing brands since I haven’t been having the best luck with Dewalt.

            This hammer drill is very good. I was looking to upgrade my old 20v dewalt and wanted to be able to hammer drill concrete without having to change drills. The flex volt battery lasts longer than stock 20v.
