Porcelain tile bit

[Jupiter01]

Where do you buy these from?
They are quite expensive at Screwfix and Toolstation and don’t last very long.

Would appreciate your suggestions on which ones to use.

Thanks in advance.

If you want a longer lasting/better quality bit, look at Marcrist.

That said, I often find that the smaller 6/7mm bits get clogged up with the cores from the hole. The diamond is still sharp but the core is blocked.

edit- in theory a Macrist bit should do over 50 holes.

At that price, I would not expect them to last very long
