Porcelain sink

Porcelain sink is composed of cast iron body and a coat of porcelain. You need drill bits for cast iron and plenty of cutting oil (machine shop item). Use a carborandum ball (~1" diameter on 1/4" shaft, say) and expose the cast iron base at the location where you aim to install the faucet.

It goes without saying that you site this hole very carefully, avoiding, for instance, the ridges underneath in the cast iron sink body. You have to be able to tighten a hex nut from below and you need room.

Start with a small diameter drill bit such as 1/8" and make a hole with the aid of cutting oil. Make sure it's in the right place. Use successively larger diameter drill bits with plenty of cutting oil, until the hole size is 7/16" inch. Use the carborandum ball to clean off any burr. Call 888-928-3794 if you need further details.     Back to faucet installation                    Top
