  • Stainless steel sink drainhole off by 1/8"

    Help! We had a stainless steel sink installed as part of a reno. The drain hole is 3 3/8 not 3 1/2. The garbage disposal flange won't fit. We can't send back the sink because it is under a quartz counter top. I've called plumbers, fabricators, blacksmiths...to no avail. It needs to be "shaved" 1/8". Who can I get to do this? what tool should they be using? What questions should I ask before I let somebody touch the sink (to avoid potential damage)? Thanks!

    I ordered it through Signature Hardware, never thinking this would happen. I find out the sink is made in India.

      Uh.... go to walmart and buy a dremel tool. Use it with a grinding stone to make the hole the size you need!

            First of all, the sink went in, it will come out.

            Second, you only gotta take a 1/16" off to get your 1/8" extra diameter. I'll second the Dremel.

              Electric drill with a carbide bit. Keep the bit circling the opening so it doesn't offset and pack a lunch; you're going to be there for a while.

                1/8 inch, I guess thats about 3mm? The Dremell will do it. I would prefer a straight grinder (low speed), and a grinding roundell about K 60 , perhaps 2 or 3 of them. (the ones that look like mini sander belts)
                You,ll be finished in about 5 minutes!

                  Hey I'm real close to that location. Anyone want me to come barging into building with a camera extremely upset spitting when I'm talking and not taking no for an answer?

                  This can be arranged...

                  Show us on video; I've always had trouble with dremel tools slowing down when you're trying to grind.


                  Since I'm asking you of a video, I needed my carbide two days ago and couldn't find it, but I'm going to produce a video of what I'm describing. I've opened up holes in stainless with a carbide...the speed is dictated by what gauge the stainless is.

                    I believe we have finally found the solution. I have found a Blacksmith. I appreciate the feedback, but we are not good with power tools.

                    In speaking with the Blacksmith, he has already done exactly the same thing with another sink that was purchased at IKEA. The real lesson here is that sinks which are foreign made need to be checked out to make sure they can take a standard garbage disposal before installing them under quartz or granite counter tops, because perhaps the quality control isn't there on the foreign made products.

                    It also reminds me to ask where things are made. Thanks for all the advice!

                      Glad ya found some help. Blacksmith will probably get the sik real hot and stretch out the hole to the size needed.
