The DCD701F2 also comes with a nice belt hook, and the battery gauge is located on each battery rather than on the tool, so you can check batteries without having to insert them into the drill. And the LED is positioned so that it illuminates the drill front better than most. The battery is designed so that the drill can stand upright when not in use (other drills, like the runner-up Bosch, need to be placed on their side). The molded handle seems to account for every curve and bulge of the hand, making this drill the most comfortable we’ve ever held. The DeWalt drill’s power is on a par with that of some other models we looked at, but it particularly excels in ergonomics and convenience features.
These results show the drill can handle just about anything within the four walls of a home, and even the occasional foray into more aggressive work, like a small decking repair.
In our tests, it bored 30 1-inch holes through a 2-by-10 on a single battery charge. Also, since rotary hammer drills are likely going to be used frequently, I made sure to only include trusted, well-known brands, and excluded any obscure options that, even though they’re a bit cheaper, just aren’t worth the risk of not being durable enough to do the job.The DeWalt DCD701F2 Xtreme 12-volt drill combines power, comfort, and convenience in a way that none of the other tested drills do. Since different users will be using their drills for a range of applications, I did my best to include varying levels of power, with options that deliver 1 all the way up to 6.8 joules. I've used my personal experience using rotary hammer drills in the past-as well as extensive online research-to put together this list of the best options. On the other hand, corded drills offer unlimited running time, but they do require you to have an outlet nearby, and introduce power cords that can be frustrating to wrangle and add a tripping hazard to your job site. While cordless drills are convenient for their portability and lack of extension cord, you are limited by their battery runtime. Higher joules usually means a heavier drill though, so keep that in mind.Ĭordless versus corded power is something else to consider. The higher the joules, the more energy the drill will transfer into the workpiece, and the faster it will finish the job. The overall power of the rotary hammer drill is another factor to consider, and can be assessed by looking at their impact energy-which is measured in joules (J). Other models may have a drill-only mode that disengages the hammer mechanism, which is necessary for core drilling.
This will allow you to use the drill with a chisel bit, which is essential for most demolition tasks. For example, although all our options will have a primary mode for hammer drilling, some will also have a hammer-only mode that does not rotate the bit. What to ConsiderĪlthough most rotary hammer drills look similar, there are features that make some more useful than others. They’re heavier and bulkier than standard hammer drills, but their added efficiency is usually worth the extra weight, completing tasks in seconds that would take lighter-duty drills several minutes. These drills use an air-powered piston to supplement their drilling mode-think of hitting the back of the drill with a hammer while you’re drilling-which creates a powerful impact per blow, and makes them extremely effective at heavy-duty tasks. While a standard hammer drill and a masonry bit can handle a few small concrete or masonry holes, you probably want to get a rotary hammer drill for larger and more intensive jobs.
