It might be possible to make clean, consistent holes in concrete without a rotary hammer drill, but there’s no reason you’ll ever need to find out. That’s because Amazon has a cordless rotary hammer from a beloved brand on sale right now, one that, unlike a drill or impact driver, is built to go through the hardest materials with ease.
The DeWalt 20V Max SDS Rotary Hammer Drill is on sale for $230 at Amazon, a 34% discount off of its $349 list price. That’s the lowest price for this bare tool (no battery included) at Amazon in at least 90 days, all for a powerful tool that runs on the same batteries as the DeWalt tools you already own.
This tool has a brushless motor and German-engineered mechanism that puts out up to 1,100 RPM and 2.1 joules of impact energy, enough to quickly bore holes in concrete. It also has an accompanying active vibration control system that reduces the vibrations you feel from all that energy while using the tool. Among the other user-friendly features are a lightweight design that makes this tool easy to hold overhead and for long periods of use. And because it’s cordless, you don’t have to worry about running an extension cord (or getting tangled in one) while you use this tool, which has three modes — drill, hammer drill, and chip — that you can choose from depending on what you need it to do.
One shopper wrote that this tool is a “powerful and reliable rotary hammer drill for DIY projects.” They added that its “power, versatility, and cordless convenience is perfect for tackling a wide range of home improvement projects.”
Another customer called it “a great heavy-duty drill for concrete and rock probing,” the kind of tool that “with good masonry bits goes through concrete as easily as my DeWalt drills go through pine.”
