It’s 20 times brighter than the previous model and includes a 20-minute shutoff function that allows for extended worktime in dark or confined spaces. The DEWALT DCD996P2 hammerdrill includes a bright, three-mode LED spotlight that enables you to work in waning daylight or in confined spaces without losing sight of what you’re doing.

Its lithium-ion battery means you’ll have full cordless freedom, making it perfect for use in your garden or backyard. This ensures that whatever type of bit you’re using, it will hold on securely and without slippage. The DEWALT DCD996P2 cordless drill also features a heavy-duty ½-inch ratcheting nitro-carburized metal chuck with carbide inserts. The motor’s high-efficiency design supplies you with up to 75% more run time compared to a brushed model. It has the capability to go from 450 RPM up to 2,000 RPM at its upper limit. The variable speed brushless motor of the DEWALT DCD996 provides steadfast power. 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.Tackle any garden project with power and safety 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.
