Welcome to The JB Forums,

A diamond tipped bit works well.

You'll need a diamond bit for porcelain. Lowes and Home Depot have them. Look for those from Hitachi, in the Tool dept. near the other drill bits, under $20. Follow the instructions including keep the bit wet for extended life.

Thanks.
What about the speed? fast or slow?

[Mike2]

Follow the directions which will recommend a sloooow speed.

There are two speeds you can drill at.

1) What Mike said: Slooooooowww!!
-OR-
2) I-just-cracked-the-tile

finding that "slooow speed" and the speed of "ohh $#%*, I just cracked the tile" is a fine line.

being that the tile Is is supported by thinset & Hardi you have a good chance you won't come close to cracking it. I would drill a smaller pilot hole first before using the size you need.
