This style of bit works wonders on tile. Goes through so fast you don't need to worry about water, or cooling it down. Porcelain is another story. That still takes time, but for standard tile, these make the job real easy.
There's a style with the single arrowhead tip, too, but the intersected ones seem to work so much better.
