With a cordless impact drill, you're not bothered by cords. That means you can work wherever you want, even if there's not a socket. You can easily drill holes in stone with the impact function. The drill rotates, but also moves back and forth. Most cordless impact drills are part of a battery platform. This allows you to use 1 battery for your cordless impact drill and other (garden) tools from the same platform. There are cordless impact drills from various brands, such as a Makita cordless impact drill or a Bosch cordless impact drill.
