Just heard few horror stories about drilling and cutting porcelain tiles,

If it comes in a box, you just pick another one out and try again -
you'll lose a few, but not many. If it's an expensive hand-decorated
one-off, then you might have more to worry about.

I treat them like drilling glass:

Use a drilling machine, not a hand-held drill. This is the most
important part.

Use a carbide "leaf" bit

Use a good backing support, such as an undrilled scrap of timber and
maybe even a layer of polyethylene foam (flooring underlay) on top.

Make a circular wall of glazier's putty and put in a little paraffin
as lubricant.

Drill gently, with little downforce.
