They have these at Home Depot. They are great for removing bits of ceramic material. Start at an angle to keep it from walking, then straighten out and you’ve got yourself a hole.
I use them to hang vent hoods. We put plywood up, tile guy goes over it, then use this bit to gently make the bolt holes without damage.
These are not as good for tile as that bit, but easier to start and good for concrete other materials as well.
