What you using for porcelain tiles? The Bosch multi drill bits are a great alternative to the expensive diamond bits get up to 10 holes on Porcelin tile n many more on ceramic. And only afew £ from screwfix.
Found screwfix erbauer to be good for the price. Got a few sizes, must of done at least 40 holes with the 8mm in tough porcelain tiles, for about £15 I think that's good.
