I need to drill a hole for a soap dispenser in a cast iron sink, that has a porcelain enamel. What is the best way to do this without ruining the sink?
The 2nd post here has some instructions, but I'm not sure:

sure, J, here goes. drill a 1/8" hole using a titanium or cobalt bit at high speed. cobalt is the best. the bit you showed me is the best but a vari-bit will also work. forget the jerk that recomended alcohol, it will ignite! use anti-freez in a spray bottle and have someone else spray while you drill. just keep steady pressure on it and you should get through in a few minutes. be warned, dogs and cats think anti-freez is yummie but it will kill them!!! good luck, dude and be carefull!

I searched far and wide and didn't find much on this topic. My local plumbing supply house said it was impossible and to forget it. I was given a nice porcelain & cast iron sink with a faucet, but I needed to drill a hole for my reverse osmosis faucet. I placed duct tape over the area I wanted to drill, then drilled first with a 1/4" glass & tile bit (just to get through the porcelain). Then I switched to a Unibit that started at 1/4" and stepped in increments to 3/4". I drilled in slow speed and poured anti-freeze on it while I drilled to keep the bit cool. It took awhile, and it chipped a bit around the hole. The faucet flange more than covered that however. Mission accomplished! Good luck, and yes it can be done. Just drill the smallest hole you need. The smaller the hole, also the easier it is to drill.

go to wally mart and buy a plastic soap dispenser and place it next to the sink if you cannot afford to buy a sink with the built in hole, what makes you think you can make a hole in something with no experience?

take a sharp punch, at the center of the hole you are wanting to drill, lightly hit the punch with a hammer, causing the porcelain to chip, then drill the hole
porcelin is a glass, so you have to remove a small place for the drill bit to cut, \or start with a carbide drill bit, then use a steel bit, sitll have to punch it,

You need a carbide or diamond holesaw of the correct diameter. I like to make a dam out of plumbers putty and pour isopropyl alcohol in it to cool the saw bit. Go slow until you get through the porcelain coating.

Use a diamond coated tile and stone cutting drill bit. Home depot or Lowes should carry this. It is used to cut holes in granted or stone.

Take it slow, slow, slow or you will crack it. Also, pour water on it while you are drilling to keep it as cool as you can. Be prepared because it will take a little while.
Good luck.
