You can not drill ceramic tiles the way you drill wood, bricks, or metal.
You need to buy a special drill bit for this purpose. This is a drill especially manufactured for drilling ceramic.
Here is how this drill bit looks like
Before you start drilling, you should tap lightly in the exact place you want to drill with a nail or a screw, so that there is a small nick in the surfaced of the ceramic tile. You need to do that lightly so as not to break the tile.
Once you have the place marked drill using the special drill bit with low velocity and without a lot of pressure.
Here is a video of how to do it.
