Hi all
I am building a dry sink for a vanity and the plan is to turn it wet by purchasing a pottery/clay bowl and drilling a 1 1/2″ hole in the bottom to create a sink.
I have a good set of hole drills from Lee Valley to use on the job.
Any tips from your experience ?

Very slowly. Similar to drilling ceramic tile. You might want to practice on a tile to see just how much speed and pressure you'll need.
I can't remember where I "saw" them but there are hole saws out there that have diamond chips on the cutting edge. Another thing that would work is to use a regular hole, with the teeth nearly ground off, with 60-80 grit silicon carbide lapping compound. Puddled in a molding clay dam using low RPM.

You can buy hole saws that are made for cutting through granite, marble, etc. As stated, they have diamond chips on the edge, or in some cases, carbide. Harbor Freight sells them but I think they're only in a set. For a one-time shot, go to a big box store and see what they sell.
As the others have said get a diamond or carbid hole bit.
I would also make the hole from the top with the at least an inch of water in the bowl, and stop occaisionally to let things cool down.
Thanks to all for your advice. I'll let you know if I wind up with one hole in the bowl, or a bunch of pieces. Stewie"Always a new way to screw up"
