![]() ![]() 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. He even rewired their bass boat for fun one weekend as a young teenager.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. From his dad, he was able to learn irrigation, landscaping, car maintenance, basic electrical, and more. In fact, Kenny still uses several pieces that his grandfather made more than 30 years ago.Īt home, Kenny’s dad made the family budget stretch further by doing many DIY repairs around the house. Building everything from bookshelves to lazy Susans, he became extremely accomplished while his young grandson observed, fascinated at the way raw wood could turn into something both beautiful and functional. His grandfather was an airplane mechanic in WW2 and took up woodworking as a hobby after retiring from the power industry. Kenny’s life around power tools started early. While that might not sound like a direct line into the power tool industry, his analytical and scientific mindset help him design repeatable testing methods for Pro Tool Reviews’ head-to-head testing and offer highly objective comparisons in his reviews. Price: $149.00 bare, $189.00 kit with a 2.0Ah battery and charger With its reduction in size, higher available power than any of the other models, and hammer mode, it’s easily our top recommendation of the group. The DeWalt DCD799 is the king of the Atomic drill line when it comes to performance. In our opinion, it’s worth getting the newer models unless you catch the older ones on a clearance sale. DeWalt Atomic Drill – Currently Available ModelsĮven though DeWalt has updated drill and hammer drill models, you can still get your hands on the previous models if you prefer them.Īt the time of writing, the prices of the previous models are very close to the updated ones. While DeWalt uses unit watts out rather than torque as a power measurement, the updated models are clearly more capable.Įven with the DCD799’s higher power level and enjoying the title of the best cordless drill in DeWalt’s Atomic series, There’s still some room to bring the performance up in the speed department if it’s going to challenge the top compact model available. The upgrade in power is certainly welcome. So where do these tools fit in the grand scheme of things now?ġ650 RPM doesn’t challenge the top drilling speeds of the best in the compact class, but it’s still relevant. They also drop about 1/2 an inch in length.ĭropping size while improving performance is always a positive. Even if you don’t need the hammer function, that’s a big enough difference to warrant buying it anyway.Ĭompared to the previous versions, the top speed is the same, but both models have significantly more power than the 340 UWO of the DCD708/DCD709. Normally, the hammer drill is exactly the same as the drill driver version, but this time, the DCD799 has nearly 30% more power than the DCD794. What’s unusual is the power difference between the two models. However, the updated models aren’t as close to one another as we’re used to seeing. These take over for the DCD708 and DCD709 which were your previous top choices on the Atomic line. ![]() The DeWalt 20V Max Hammer Drill (DCD799) covers the same functions and adds a hammer drilling mode for concrete and masonry. The DeWalt 20V Max Atomic Drill Driver (DCD794) takes care of your hole-drilling and fastener-driving tasks. In the latest generation, you have two options to work with. ![]()
