I have ceramic tile on an indoor pool spa. I want to drill a one inch
hole in it to mount (relocate) a new air button control for spa jets.

What is the best way to attempt this without damaging or cracking the
tile? There is a layer of tile mounting board and then steel framing of
the pool mounting frame under the tile.

Do I use carbide tip bits? What best suggested bits/drill to use? All I
have available is a 1/4 drill.

Thanks for comments.
