Yep, start on a 45 degree angle until you get a groove then slowly stand it up.
It's in the thread title.Didn't it say cast iron did he delete that or was I just seeing things?
cast ironBeings how we don't know what material he's trying to drill, I can't answer the question.
Oh that's fancy!I saw A Hole in the thread title and had to check it out.
But seriously, I wouldn't risk it. I would use the Relton PC-20 1-1/4" Porcelain Cutting Hole Saw Kit. It's not cheap, but nothing that is worth anything is.

And I found out about it on the Rigid forum a few years back. The member "plumber rick" had a thread on it. I can't link it do to CT rules, but a google search will get ya there.
That thing is pretty slick, but a little more than I want to throw at a one time tool. I'm still going to consider the carbide hole saw though. I would probably need a diamond pilot bit to get through the porcelain.I saw A Hole in the thread title and had to check it out.

too trueCheaper than replacing the sink.
I wouldn't bother with the pilot, but if you have a diamond hole saw that would be great for getting through the enamel.That thing is pretty slick, but a little more than I want to throw at a one time tool.

Did you mean jigsaw? What would keep it from chipping the enamel?BCConstruction said:I have cut hundreds of holes into cast iron soil pipes for saddle with just bi metal joke saws and a little cutting oil. It should be just as easy on a cast iron sink.
Cast iron stink stacks are not coated in enamel and cosmetics never comes into play.I have cut hundreds of holes into cast iron soil pipes for saddle with just bi metal joke saws and a little cutting oil. It should be just as easy on a cast iron sink.
If your worried about dulling your cutter going though the enamel Drill from the back till you hit enamel then punch the enamel through from top. I'm sure there's gonna be a flange at least 3/8" around the insert so if it chips a little no big deal.TNTSERVICES said:Cast iron stink stacks are not coated in enamel and cosmetics never comes into play.
