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. 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).
