Drilling a hole in stainless steel sink
Any suggestions on what tools are best for drilling a 11/4″ hole in a stainless steel sink for an instant hot water faucet? Also, how do you burnish out the blemishs that I made while I was trying to drill the hole?

Slug Cutter. Rents for pretty cheap. One local store will even loan them if you bring them back undamaged. Electricains use 'em for cutting holes in boxes.
As to damage...dents? scratches? gouges? Brushed or polished surface? How big an area?

Everything will be okay in the end. If it's not okay, it's not the end.

Tough stuff to drill. I would probably drill a 1/4" hole and then use a 1 1/4" hole punch. Its been a long time but I think that's what I have used.
I recently cut one with a holesaw (Lennox or other quality brand with hardened teeth). Use a little oil.....works fine.

SS can work harden is a flash, water as a coolant is a better choice. Having machined literally hundreds if not thousands of pounds of SS in my life....spray a little oil on a dull cutting tool and watch it snap. Using a new sharp tool is what saved you.

Thanks for the tip - cooling is more important than lubrication with SS. That helps explain some previously observed phenomena.

Never underestimate the value of a sharp pencil or good light.
Ditto kilbo's post - good quality hole saw - Lennox and Milwaukee come to mind with a bit of oil.
Need more info as to repair - if brushed finish, try wet or dry sandpaper.

Fill out your profile and there might be someone near that would loan you something. You do not have to tell all your secrets (:-).
when Imerc was here, he did one for my wife using a step drill bit in about five minutes.
