![]() ![]() 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. The only potential drawback is the price.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. The verdict: Hammer drillsīased on our testing, the DeWalt DCH253M2-GB is the very best hammer drill out there, with excellent performance across a huge range of tasks using all three modes: drill, hammer drill, and hammer. Weight – For routine DIY tasks, it’s recommended that you go for a lightweight model, which will generally come in at around 2kg. If you’re planning heavy duty work, you’ll want the option of a higher speed setting, but for lighter work, such as driving screws, a lower speed setting will suffice. ![]() Variable speed settings – Hammer drills will generally have two or three speed settings, which makes them great for multitasking. You will, however, need access to a power source to use them, while a cordless model can be charged up and used wherever you need it. A 550W drill will be powerful enough for most routine DIY jobs.Ĭorded or cordless? – Connected directly to the mains, corded drills tend to be more powerful than their cordless cousins and are therefore better suited to heavy duty work. ![]() Power – When working with masonry – stone, brick, cinder blocks and tiles – go for a higher wattage, while a lower wattage works well for other, less heavy duty materials, such as plasterboard. What should you look for in a hammer drill? This makes them better suited for tougher jobs where you need power and stability. These drills have two handles – one to turn them on and off and the other to keep them steady while in use. On the other hand, regular hammer drills allow you to do everything you would with a combi, but with a bit more oomph. If you’re looking to carry out everyday DIY tasks such as drilling holes in walls and driving screws, a combi drill is your best bet. A combi drill – which combines a hammer drill with regular drill and drill-driver modes – drills into wood, metal and masonry. Hammer drills FAQs Which drill should I buy: Regular, combi or hammer?Ī hammer drill refers to any tool that features a hammer mode – this can include both regular drills and combi drill options. That said, if you need a powerful hammer drill that gets the job done, this is one of the best you could buy. You should probably also wear ear defenders while using it. We wouldn’t necessarily recommend this drill to DIY newcomers, as it truly is a powerful piece of kit, which means taking precautions like clamping down the materials you are drilling into becomes especially important. If you have a lot of work to do in a short space of time, no matter what materials you’re working with, this will see you through with no issues. And when it's switched to drill mode, it makes even lighter work of tasks like drilling holes in wood. ![]() When hammer mode is active, it bores through tough materials like cement and masonry with minimal fuss. The tool breezed through every task we threw at it during testing. This is a contractor-standard hammer drill that gives you impressive drilling power at a remarkably affordable price. ![]()
