With a cordless combi hammer, you can drill large holes in concrete and other hard types of stone. Thanks to the battery, you're not bound to a socket. In addition, you can do light demolition works with a cordless combi hammer thanks to the rotation stop. Connect a flat chisel or pointed chisel to the combi hammer to remove tiles from the wall or remove mortar joint. Use a battery with at least 4.0A, because heavy work requires a lot of power. So you're sure you won't be without power halfway your job.
