I'm looking for anyone's experienced advice regarding drilling a hole in a glazed
stoneware basin. A friend wants to make a bathroom sink out of a bowl he already
has. He wants only a hole in the bottom to drain the water. Holes for faucets aren't
necessary.
I've successfully drilled holes (slowly) in a half dozen stoneware pot floors in the
range of 5/16" thick using a carbide-tipped drill. The working end of the bit I used is
an arrowhead-shaped blade, like a flat shovel, which has been sandwiched into a
regular steel drill shaft. Any hardware in the USA carries this kind of bit. But the
hazards of cracking the basin while drilling a hole with the diameter necessary for a
drain hole in a sink may be another story.
Have any of you attempted this? Where did you find a bit of appropriate size?
From my experience with smaller pots and smaller holes, cracking the pot/basin
seems to me not to be a risk as long as I drill slowly and without too much pressure.
Any experienced opinions?
Thanks -

I had to get a whiteware sink redrilled and I took it to a local company
that makes things like granite countertops. They have diamond drills in
appropriate diameters. Easy job for them.

Curtis:
Any good industrial supplier can provide you
with a masonry "core drill". For that matter,
most well-equipped rental centers have them too.
They can also rent you the bit you will need to cut
the appropriate size hole for the tailpiece/popup
to be installed in. ( Like a hole saw, but for boring
straight and true holes in concrete.) You don't
want to buy either one, the drill motor or the bit,
trust me. Get the popup/tailpiece in advance and measure it
being sure to leave room for the radius (?) where the rim
of the tailpiece meets the pipe part. That's why there's a flange
on it...to allow for some "wiggle room"
You might have to build a wooden platform to sit
the core drill on in order to get the proper placement,
but it is do-able. You might wrap the bowl in a
garbage bag, then fill the inside of the (wrapped) bowl
with that expanding "foam in a can" to provide some
backing to support the bowl bottom while drilling.
You will probably be drilling from the outside of the bowl inward.
Use plenty (!) of water while drilling, and the slowest
speed available, or pulse the drill on and off to keep the rpms
very low. Little pressure as possible too. You don't
mention how thick the bowl wall is, but that should do it.
Take your time...do it once, do it right.
Good Luck!

On "Ask this Old House" a tile installer drilled a large hole in ceramic
tile using a hole saw, I'm sure it was made for doing tile so you might
contact a tile company.

For a single hole, I'd suggest calling a tile / stone contractor, or =
shop. You can even try glass / mirror shops. They have similar =
equipment.
The only way is to use a diamond coring drill. You can buy one for a =
reasonable price, but it wouldn't be cost effective. A coring drill in 1 =
3/4 to 2 inch size would be about $45 - $60+.=20
A tile shop would probably only charge you $10 - $20 to drill the =
opening.( Maybe less, it doesn't take long.)

If you still want to try. I buy my drills from Master Wholesale. =20

Curtis, drilling holes in stoneware is best done before the clay reaches
that state. However, if you are so inclined, there are a variety of drill
bits and hole saws that will accomplish the task. Diamond cutting tools are
what has worked for me when I engaged in this ill advised activity before I
learned to say no and never again. Wear a properly fitting resperator! Don't
use a rotary drill with a masonary bit, you probably end up cracking the
pots. Use a good, strong drill at low speed or a drill press. Talk to the
folks you are buying the cutting tool from and let them know what you are
doing. They can be very helpful.
Just follow any of the links from the following Thomas Register site. Pick
the company closest to you.

If you're brave to do it yourself try a piece of duct tape over the =
place where you are drilling and put a piece of solid styrofoam =
underneath to provide a cushion to drill into to absorb the vibration. =
I saw this on some Discovery Channel home improvement show some time =
ago. A lady did a similer thing and it worked!
If it was me tho' I'd take it to a bath fixture place. This bowl made =
into a bathroom sink craze is hot thanks to Extreme Makeover Home =
Edition and such shows. I love that show. Almost makes me cry! Like =
Queen for a Day only Extreme! Makes me wanna take a hammer to my house =
but I don't have their budget!

I always drill stoneware (and earthenware for that matter) resting the
piece I'm drilling on a piece of foam plastic, in a sink with cold water
running on the drilling point to cool and lubricate, at medium speed,
using a standard masonry drill bit.
