Some of the results were truly surprising. ![]() Through hands-on testing, we found a number of drill bit sets that rise above the competition and help make holes in myriad metals. Depending on the type of metal the user is drilling through, some bits suit the task better than others. Labels on drill bits indicate the type of material for which they’re suited, so it’s easy enough to find ones that are designed to drill metal. Many drill bits can pierce through more than one type of material, but not all drill bits can drill through metal without heating up and snapping in half. But for more-production-oriented work, such as putting down decking or building a garden shed, they make a noticeable difference.Home improvement centers often dedicate an entire aisle to drill bits, which come in a plethora of types and sizes for drilling holes in a variety of materials. For around-the-house tasks, the added speed and power are often unnecessary. The well-positioned LED can also be switched on independently of the drill, a unique feature that makes it a rudimentary flashlight (which could come in handy in nearly any crawl space). Compared with our 12-volt pick, this larger drill completes tougher jobs much faster, doing the same work in less than half the time, with a battery that lasts longer. This is a larger, 20-volt drill, but it shares all of the most important characteristics of the smaller, 12-volt DeWalt: It’s very powerful and extremely comfortable to hold and use, and the little convenience features, such as the belt hook and the case, are spot-on. If you take on projects that have you drilling lots of holes and sinking long screws, we recommend stepping up to the DeWalt DCD791D2 20V Max XR Li-Ion Brushless Compact Drill/Driver Kit. The DCD701F2 also comes with a nice belt hook, and the battery gauge is located on each battery rather than on the tool, so you can check batteries without having to insert them into the drill. And the LED is positioned so that it illuminates the drill front better than most. The battery is designed so that the drill can stand upright when not in use (other drills, like the runner-up Bosch, need to be placed on their side). The molded handle seems to account for every curve and bulge of the hand, making this drill the most comfortable we’ve ever held. The DeWalt drill’s power is on a par with that of some other models we looked at, but it particularly excels in ergonomics and convenience features. These results show the drill can handle just about anything within the four walls of a home, and even the occasional foray into more aggressive work, like a small decking repair. In our tests, it bored 30 1-inch holes through a 2-by-10 on a single battery charge. The DeWalt DCD701F2 Xtreme 12-volt drill combines power, comfort, and convenience in a way that none of the other tested drills do. ![]()
