        Why does this kit have the DCF845 listed as the impact driver? Isnt this model number for this particular kit (DCK2112QQ2) supposed to have the DCF860 impact driver instead? Other retailers lists the DCF860 on this kit same but Home Depot doesn’t?

          I'm trying to install post brackets on existing concrete patio but I keep hitting rebar. My standard household impact will not do the job. Will this hammer be strong enough to drill through rebar (with the appropriate rebar cutting bit of course)?
          BySep 5, 2026
          1 Answer | 
          Answer This Question

          We do not recommend using the DCH172B for rebar drilling.

                Can it up root tiles?
                ByJul 25, 2026
                1 Answer | 
                Answer This Question

                The DCH172B can remove light tiles, but it is not ideal because it only features rotation with hammer and rotation modes, lacking a hammer only mode.

                  The drill works great. It really shines for drilling small holes for pinch nailing. If you have enough batteries it also works good for dowells. I use this one way more than my corded one now.
                  by
                  ne of my favorite things about this tool is how lightweight and compact it is. It’s easy to handle in tight spaces or when working overhead, which really reduces fatigue during longer jobs. Despite the smaller size, it still feels solid and well-built, exactly what you’d expect from DEWALT.

                  Swith selector jammed and POOR Warranty service.
                  In less than a year, the selector jammed, tool it's barely been used. I took it to the DeWalt service center, and they told me the warranty is only for one year and wanted to charge $99 for the repair. and even though Home Depot claims on their web a 3-year warranty for this tool. Now, two years later, DeWalt won't cover it. A tool company only offering a 12-month warranty says a lot about the quality of their tools, since even they don't trust them beyond 12 months.

                    I was looking to update my drill and impact with new batteries. The power pack 4ah seems to be quite a bit stronger then the original batteries I had. The dcd1007 drill is extremely powerful! With the kit I also got the dcf845 impact driver with 2 4ah power pack batteries. The impact is impressive as well! With these 2 I was able to complete some awesome projects so far!

                    I am very satisfied with the product. The drill is very powerful even in concrete and the battery lasts like crazy. What's more, when I took advantage of the Black Friday deal, I got a 6ah flexvolt battery that is suitable for my other Dewalt tools!
                    by
                    I like this kit really good deal and like the new safety features, hammer drill is just a little big, I just have it for like a month. Fast shipping!.. Great buy

                    Dewalt is the best. This tool can put a hole in anything. Concrete? Yup. Brick? Yup. Wood? Why not?! If you’ve got 20v batteries, this is what you need.

                    A really good hammer drill for being so compact. I like the weight, grip and power. I'm generally a Milwaukee guy, but Dewalt came through with this tool.
