    Answer This Question

    Model of this is DWD520 without the "K" at the end and doesn't include the hard carrying case as DWD520K with the "K" does.

          Answer This Question

          The hammer drill would not have been tested with that and would not be recommended by the manufacturer DEWALT.

          By|Mar 10, 2023


            What model is this? Would be convenient if Home Depot would include that in the description.

            DWD520 very good

            By|Aug 22, 2023

              Yes, not sure why they wouldn't include the model number unless they don't want you to look up the model online to do comparison shopping. The model is the DWD520. I purchased one from the Home Depot store online and had to return it as the unit arrived with a damaged box. They shipped the drill in the manufacturer's product box without any protection and thus the product arrived damaged. I am never shopping at Home Depot online again.

                I want a combo drill suitable for anchoring into concrete AND that has a slower-more-torque setting to mix mud with an egg-beater bit. Is the slower setting good for mixing mud --- and I mean earth mud for adobe.

                Answer This Question

                For mixing "mud", you need a drill with a low maximum RPM, but powerful. In the cordless line, the DCD130 60V MAX Mixer/Drill is made specifically for this application.

                  Yes. This drill has three settings: slow drilling, fast drilling, and hammer mode. The easy to install handle makes mixing a breeze.

                    Hi Will. Thank you for your question. According to DeWALT Customer Service, the smallest bit the 10 Amp 1/2 in. Variable Speed Reversible Pistol Grip Hammer Drill will take will be a 5/32 up to 7/16. The size will depend on the material you plan to drill into. For more information, please give DeWALT Customer Service a call at 1-800-433-9258. Please let us know if we can be of further assistance. Rick_HD_OC

                    Best drill I've ever owned.
                    This 10.5 amp drill takes a beating and keeps going. One time I tried to mix floor leveler that was too thick and saw smoke coming out of the drill. I immediately stopped and thought my drill was done for, only to find the next day it ran fine, and has been running fine for two years since. I've included a pic of this 5 year old drill to show you what it's been through. Usually I don't write reviews, but I've come here 5 years past purchase because I'm so impressed with this drill.

                      Just ordered this Dewalt 1/2 " Hammer drill. Really looking forward to receiving my item. I've had many Dewalt products in the past and this product should be no different in quality. Looking forward to receiving my package and putting this hammer drill to good use.

                        Bought a week ago and I have used it for adding a wall to my concrete wall.

                          Powerful, safe, durable and just the right DIY tool when batteries don't work.
                          I bought this powerful, corded drill specifically to mix concrete resurfacing mud 40 pound at a time. The torque was exactly what I needed to ensure consistent and thorough mixing. The handle can be mounted for left- or right-handed people, so the ergonomics are exceptional. Even after 12 bags of mud in a single day, the motor was not hot and the drill continued to function perfectly. I also found the trigger to give excellent speed control in forward or reverse to avoid splattering the mud. I would definitely buy this drill again.
