I want to add an extra faucet to my kitchen sink (too long a story for
this thread but it involves my two wells, one with great drinking water
and the other that is higher capacity).... The sink is a nice old cast
iron sink with white enamel coating. First, can I reasonably drill a new
hole in the sink for an additional faucet? If yes, how is it best done?
Will a standard drill do this? The sink is very thick, and I don't want
to damage the surrounding enamel when I drill it....
Thank you in advance for any suggestions.
Why not just put a lab-style faucet with a gooseneck spout through the
counter next to the sink? Or maybe an old commercial laundry-sink style
wall-mount faucet on the wall above, assuming the spout is long enough. That
way, you can shove the extra out of the way when you aren't using it. Any
new faucet is going to require more than one hole anyway, isn't it? Does the
sink have enough flange are to allow that? I suppose a carbide or diamond
hole saw would drill through the enamel, but I'd be paranoid about it
crazing or flaking off, especially if it is old.
The sink stands alone on its own cabinet, so there is no surrounding
counter and the wall behind would not be easily accesed..... There are
single hole faucets for sale, especially the bar type faucet which is
all I need for this spare one...
Yes, it can be done. It is very difficult to drill cleanly
through the porcelain finish.
Look in your yellow pages for a tub refinisher.
Use carbide grit hole saw to get through the porcelain and a
slightly smaller, best quality, hole saw to drill through the cast

As someone said, the porcelain enamel is the problem, not the iron...cast
iron drills easy. Just thinking out loud but I wonder what a torch
(acetylene) would do? Would it melt the porcelain - which is just glass -
in a localized area?
One thing that might work is to lay out the hole and grind away the
porcelain before drilling. I'm thinking of something small like a Dremel
tool using a small, fine bit or maybe sand pad to get rid of the porcelain.
You wouldn't have to get rid of all of it, just a thin circle slightly
larger than the hole you want so as to isolate the rest of the porcelain
from where you want the hole. Once isolated, drill with impunity.
You can drill the iron with a standard bit...just do it at a very slow
speed. If you do get your hole and new faucet, caulk/putty so that water
won't be getting to the raw iron in the hole.

Yes, I watched a friend do just that. He actually stood 'in' the sink for
leverage and drilled the hole with a hole saw.
The 'cut' was nice and clean. Do it at a slow speed and it might be wise to
lubricate the cut. Cast iron is actually quite "soft".
