What is the best tool for drilling holes in PORCELAIN tiles...The normal
method for tile drilling seems not to work very well. Is there any
special method/tool for PORCELAIN tiles, or is it just a difficult tile
to drill?

I tried a number of tile bits ranging from the Bosch and B&D offerings at
around £6, and even going for the £20 number from screwfix.

the big problem is that whichever drill bit you use it will get blunt fairly
quickly.

The expensive option from Screwfix was marginally better , but IMO not worth
it. They do throw in a standard drill bit as well, but I suspect this to be
more of a freebie to justify the price

I also used a tunsgtsen carbide bit on my SDS drill, after using a tile bit
to start the hole off.
This was probably the most successful option in my case. the SDS also had a
very good speed control setting which made things easier.

In all cases drill slowly and use plenty of water to lubricate/cool the bit
as you go. When drilling the walls I found two kids with water pistols did
the job of keeping the area wet:-)
Also, no matter how frustrating the drilling process may be never just ramp
up the drill speed and swear repeatedly it just completely knackers the
drill bit

So at the end of the day the tiles are just a nightmare to drill through but
do look exceptionally good.
