You use a drill bit for stone to drill in stone materials, such as tiles and brick. For example, if you're going to hang flower pots on your façade or a cozy lamp to have light in the garden at night, you probably need a drill bit for stone. Thanks to the blunt head, a lot of force is put on the stone material. Drill bits for stone aren't suitable for drilling in concrete or hard natural stone, because the material of the drill bits is too weak for that.
