                The size of the chuck. And that the 1/2" is a hammer drill + impact driver and the 5/8" is hammer drill only.

                  This drill is what made me a dewalt fan for life
                  Absolute Beast (But keep your chiropractor on speed dial) Let me start by saying this drill is a powerhouse. If you want something that will drive fasteners and bore holes with zero hesitation, the DCD999 is exactly what you need. However, a word of caution: this tool does not care about your puny human joints. The "Incident": I was tackling what I thought was a simple job—drilling a hefty hole straight through a tree. I had a heavy-duty bit chucked in, gripping the drill confidently like I was the boss. Everything was going smoothly until the bit caught a massive, stubborn knot deep in the wood. Did the DCD999 stall? Did it bog down and ask for a breather? Absolutely not. It dug its heels in and decided that if the bit wasn't going to spin, I was going to spin. ​In a split second, this yellow-and-black torque monster engaged in a full-blown alligator death roll with my wrist. I was about half a rotation away from my arm snapping into a human pretzel. The drill literally wrenched itself out of my hands, hit the dirt, and just sat there looking at me like, "Who's next?" ​Pros: ​Unstoppable Power: Seriously, pair it with a FlexVolt battery and it will chew through anything. ​Build Quality: It survived the drop without a scratch after it tried to take my arm off. I've spent plenty of time taking DeWalt tools apart and putting them back together to fix them, but this beast didn't even need a checkup. Chuck Grip: Holds onto bits tighter than I apparently hold onto the drill. ​Cons: Will actively test your grip strength and the integrity of your rotator cuff. ​The Verdict: Buy it. It’s easily one of the best drills out there. Just do yourself a favor and use the included side handle. Seriously, folks. Use the side handle, or prepare to learn how to write with your other hand.

                    Feels like new after owning for a year
                    Used this tool on stainless steel bathroom partitions while installing them, cement and brick for installing doors, and mostly drywall installing shelving systems in closets. Thousands of holes and different materials and the drill still feels new. No lack of power, head still closes around bits as if new. It just feels like a new tool about a year after buying it. I mainly compare it to using an impact for a while and the impact gets worse and worse. Im a carpenter by trade and an amateur woodworker.

                      Chuck shattered
                      Only used the tool once for a particular project and hung it on my rack. Went to use it a second time and noticed the chuck had shattered. I usually have good luck with Dewalt stuff so didn’t think twice about looking it over when I finished up my project.

                        The chuck is fixed!!
                        [This review was collected as part of a promotion.] The DEWALT DCD999B FlexVolt Advantage Hammer Drill had promised to be a game-changer, and as a professional in the construction industry, having the “supreme best” hammer drill in my toolkit is more than a luxury, it's a necessity. One particular aspect that filled me with hope was learning from DeWalt that they had finally tackled the long-standing issue of the chuck freezing. This fix was long overdue, and I couldn't help but feel a surge of anticipation as I unboxed this power tool. After unboxing I inspected it and gave it a spin. The balance, ergonomics, and feel of this hammer drill are just so good. I then went to the shop and did some real hard testing to see if I could get the chuck to lock up. I was not able to get the chuck to lock up or malfunction and was VERY impressed by the power and performance of the drill. I did lots of holes in concrete, and then drilled well over a dozen of ½ inch holes (with a ½ inch twist drill bit) all the way through treated 4x4 in about 1.5 seconds a piece. Then I got out a dull 1 inch spade bit and the drill tore all the way through the 4x4 with no hesitation in about 3 seconds!! All these tests were done on speed 3 with a 9AH FlexVolt battery and the drill was able to effortlessly handle it all. I then tried using a 5 inch hole saw. For the hole saw I finally had to put it down to speed 2. The drill still performed beyond expectations, though caution is advised with 5 inch bits due to dangerous kickback. (I seriously hurt my shin and arm myself) As for features, the work light is worth mentioning! Most drill lights do not do that much, but this light has been VERY helpful. The drill has 3 brightness settings. The first setting is about what you would expect from a normal drill except for the fact that it remains on for 20 seconds after the trigger is released before turning off. The second setting is a little brighter than setting one; it is about as bright as a dim flashlight. It also remains on for 20 seconds after the trigger is released. I usually use it on setting 2. The third setting is very bright and impressive and stays on for 20 MINTUTES after the trigger is released. I have used it on setting 3 to light up the whole jobsite, all by itself!!! Setting 3 is about as bright as a portable work light. After these demanding tests, the hammer drill swiftly became my favorite in my tool chest. I now use it regularly without any issues or the chuck ever locking up. It is also very durable and tough. I take good care of it but it has fallen more than once and been subjected to jobsite abuse and never had a drop in performance. Its reliability and power have truly impressed me, making it a reliable companion for every project.

                          Come with 2 Amp instead of 6 Amp battery
                          Purchased this kit, says it comes with a FlexVolt 6 Amp battery, it's a 2 Amp battery inside the bag, not the 6 Amp FlexVolt. Found that out when I get to the jobsite and open the kit. Very disappointed.

                            Simple and yet everything you'll want!
                            [This review was collected as part of a promotion.] Finally got to use my new Cordless Hammer Drill and I can't tell you enough about how much better this tool worked compared to my old one. To start, the fact it is cordless was amazing for me. I was in the middle of a street where extension cords were not an option. The hanging clip made it easy to carry to and from the job site. The handle was easy to adjust and secure with just a few twists and didn't budge the whole time I was using it. All of the adjustments are simple and quick to make making this thing a breeze when using it for multiple tasks. There was plenty of power behind this thing I wasn't concerned it couldn't get the job done. It would get warm, but never hot enough that I thought it might overheat. Overall I am ecstatic to have this great tool in my collection now!

                              Flexvolt Advantage Hammer Drill DCD999
                              [This review was collected as part of a promotion.] Dewalt reviews I was sent the flexvolt advantage hammer drill DCD999 and a 6.0 flexvolt battery as a sample. Overall I am very impressed and can notice an increase in power from a 5.0 20V battery compared to the 6.0 60V flexvolt. I have used this drill to mix several 5 gallon buckets of drywall mud, drill 6” holes in Sheetrock and other small drill tasks such as driving screws and making smaller holes with paddle bits. I usually use my flexvolt mixer to mix mud and concrete but decided to try the flexvolt advantage drill to see how it would mix and it did very well without bogging down at all and could definitely tell a difference in power from my regular brushless 20V drill which would normally struggle some to mix something this thick. The 999 comes with a nice screw on handle which is longer and makes it easier to use compared to the ones that came with the 996 model. It also comes with the standard belt clip too. One thing I wish DeWalt would add to more of their drills is an E-clutch to save your wrist when using large hole saws or mixing, this flexvolt advantage does not have any sort of emergency stop. The overall drill is almost identical to the 20V brushless version physically with a few minor differences, including a slightly wider base where the battery goes and the clutch is a little different. Overall a Very impressive drill and power, definitely recommend getting this drill especially if you are already on the flexvolt battery platform. It is nice to be able to use your 20V batteries for smaller projects but when you need more power you can also use flexvolts and get a boost.

                                Amazing cordless drill
                                [This review was collected as part of a promotion.] I have been using the new DCD999 for several weeks and it is an all around joy to use. The drill is very well balanced – even better balanced than the previous models. Also the rubber overmolding on the grip makes it very comfortable to use. This drill also includes a new, longer side support handle that is befitting a drill that is this powerful and makes it much easier to control. Where this drill shines is the power that it packs with a Flexvolt battery attached. I have used this drill side by side with several previous model DeWalt 18v and 20v hammer-drills drilling into old hardened concrete slabs and nothing can compete with this new drill in speed or torque. Whether you are looking to get your first battery powered hammer-drill or are looking to upgrade from an older model, this drill coupled with a Flexvolt battery will not disappoint.
