Tap holes in sink - punch or drill?

[snadge]

Ive got to put a 35mm hole in the (steel) sink for the tap, IKEA sell a punch (and pipe cutter which would come in handy) for £10 ... or should I buy a special drill cutting bit? which is best? the only concern I have with the punch is the worry that the rest of the sink around the hole might start warping with the pressure...

can anyone advise on this?

thanks

IKEA punch, works a treat

I needed a single hole in a stainless sink ( 29mm in my case ? ).

I was reluctant to use a bi-metal tubular hole saw but it worked fine and did not take long either.
