Drilling porcelain tile
 

OK, what's the trick. This stuff just laughs at a Tap Con bit in a
hammer drill (the carbide tip ends up melting) and if you try to shoot
a tap con screw in it, you get a nail. It wipes out the threads. I
just bought some Bosch super bits ($10 a pop) and I am trying them
tomorrow. They say they will eat concrete with rebar in it.

I used diamond hole saws for pipe holes. They make diamond drill bits
too. Run them wet probably.

That is next but I couldn't find one today. I managed to get 3 holes
in, 8 more to go. I might just burn up a few more bits and be done
with it. I am going to squirt some water in there tomorrow. I know the
tile guy was cutting them with a wet diamond saw but it was going very
slow for him too.

YOu have to use something to break the glaze if not using a diamone bit.
Take a carbid bit and hold it in your hand. Tap it with a hammer gently
a number of times to the glaze is broken, then you can drill it.

This stuff seems hard all the way through. I have seen a lot of
porcelain tile but nothing like this stuff. Like I said, it stripped
the threads right off a Tap Con screw, that ain't the glaze on top.

Then perhaps it's not porcelain? Pictures?

Diamond drills and a lot of patience. Being able to use a drill press
helps but I doubt that's an option for you.

I've drilled various floor tiles, glass jars, ceramic vases, etc., with a
diamond bit and cool water for lubrication. I used low speed and light
pressure. Let the drill and bit do the work.

I say that without knowing exactly what you're trying to drill into.

The tile is on the wall. A drill pres is out.
I managed to get one bar mounted today with the Bosch bits and water.
The other "ain't arrove yet" (extra credit if you can name the movie).
I have 6 more 1/4" holes to go. Pray for me. ;-)

Thanks for the ideas.

A company I worked for had a little side line in decorator quality lamps
made from Fukagawa porcelain vases. We sort of had tryouts to find women
that had the patience and light touch to drill them. The other problem
was convincing them if a $150 jug broke, well **** happens.

We used Delft too but that was a piece of cake compared to Fukagawa. The
Dutch called it porcelain but it really wasn't.
