    I've just worn out a diamond coated drill bit, drilling the first of 16 holes I need to drill into newly fixed porcelain bathroom tiles. What type of drill bit would you recommend?
  2.  
    I've had success with these, but maybe they are what you are using? I use a bit a hard board with the right sized hole in it to guide the drill bit, and loads of water to cool.

    If you're only doing fixing holes ie 6 or 8mm then I use these. They are genuinely like magic. I didn't get a water cooling kit I just repeatedly dip tip into water and take longer if it ever fizzes and I use my tiny 10.8v hand drill on screwdriver speed.

    I was skeptical and nearly bulked at the cost but WOW!

    If you are just doing one bathroom then this also works, just not for as long, and despite it saying 'dry', dip into water also.

    Weird, I had no trouble at all with an old masonry bit, on standard 6"x6" white tiles

    I've always just used a glass drill bit and cutting fluid. Forget using a masonry bit, you'll be there forever on hard tiles. Use the cutting fluid as you're drilling, don't wait for the drill to get smoking hot then quench it, you'll knacker the temper of the bit.

    I had a few bathrooms to kit out so I purchase a kit from Porcadrill. They are still going strong and the template guide for starting them off is good. You can make the job look so much better when you holes are bang on and perfect for pipes etc. I would buy them again if I needed more. I can't remember the exact kit I purchased but I think it was around £40-00 and went from 6mm to around 40mm.

    Google them for a look. They are great in my view.

    Last time I drilled tiles (off the wall) I used a ring of plasticine to keep water around the drill bit.

    I've drilled them thousands of times, always a masonary bit drilled very slowly

    Porcelain can be far harder than standard glazed tiles.

    Well I started the morning with a spade type tungston carbide tipped drill, it lasted 1.5 holes and then the spade tip parted company with the shank. As Screwfix had suggested the drill would be suitable for hard porcelain tiles i took it back and they exchanged it without question. Next I tried an Erbauer dry diamond tipped drill, no water cooling or slow speed required. I've drilled 12 holes with it and it's still going strong.

    I bought diamond coated core bits from an Ebay seller in Hong Kong. So long as you build a little moat around the bit to contain the cooling water, they work fine. The largest hole I drilled with one of these was 50mm in diameter.

    The good thing with the Erbaur diamond coated drill is that you can run them at up to 3000 rpm and they do not need water cooling.

    I'm late to this and you've reached what I would have recommended.
    I bought this http://m.screwfix.com/p/marcrist-pg750x-dry-tile-drill-10mm/73009.
    I had a small bathroom to floor tile and consequently was happy to buy expensive tiles. Which only came by the box. So I couldn't make a mistake!
    This bit was brilliant. Somewhat expensive per hole though!
    I reckon the erbauer equivalent may be the same.

    The ones I used were from Hong Kong - I got a set of five different ones for less than $10.

    This link as AUD$, but they ship anywhere - mine came in less than a week.
