I want to drill some holes in large bathroom tiles,

I've been advised to buy a drill bit specific to this task -
what should I ask for, and what is different about these bits?
I'll be visiting South London Power Tools, which seems to have
a great range of these types of things. I'd like to display
some knowledge of what I'm after though!

Easiest way I found was to get a nail or srew or similar with a good
point and gently tap in the position of the hole. within a fer gentle
taps you'll break through the glaze, this enables your masonary bit to
go through the tile in a matter of seconds (No hammer action).
If you hit a batten (the drill stops penetratiing once past the
plasterboard, get a small screw driver/bradawl and push and twist,
you'll know whether you're into wood of a nail by feel.

If wood, don't bother with rawl lpugs, just screw straight into the wood.

Don't use cavity fixings, just a red rawl plug and don't screw too tightly.
