    I have just bought a stainless steel sink with no tap hole! Any tips as to how to drill a 35mm hole in it for a monobloc tap. Seems quite flimsy. Thanks :confused:

    I've just done the same thing. I clamped a block of wood underneath the area to be drilled. Used a center punch to give me a decent start at drilling a pilot hole, around 4mm. Then used a 35mm hole saw from B&Q that stated it could could thin guage metal. It worked pretty well, though I made a point opf trying to keep the drill vertical so it cut the whole section as one.

    Then finished of will a rat tail file on the edges to finish it off.

    All it takes is skill, insight and intelligence. Therefore I find it quite easy :p

    You can jigsaw a 35mm hole in a stainless sink?
    Quicker than I can drill one?
    Neater?
    Doubt it. Lol.
    If you're going to drill it remember stainless work hardens very quickly so once U start don't stop.

    Take sink back and change it for one with a hole.

    I have done, starting from a smaller hole.

    Certainly not, but not many people have a 35mm drill ;)
    And you would want to finish it with a file!

    There was, from ChrisR
    Which ever way you do it, SHARP tools only, and the right cutting angles reduce the grief. You could drill as large as you have, then use a multisize cutter or tapered reamer.

    Yep, that'll do nicely. The normal drill on the arbor is pants though, you might want to centre-punch and predrill with HSS, just undersize perhaps.

    Yes you can drill a hole in the sink as advised by others. But seeing as you're not confident of doing it and you have a choice, why bother?

    Take the piece of cr*p back to the place you got it from and get a 'normal' sink with a nice round hole in it put there for your convenience. It is obviously some pile of junk made in the Third World and sold at a vastly inflated price.

    There are thousands of sinks out there worth buying- yours isn't one of them.
