The store won't cut it for you, but here's the deal. I spoke to a friend of mine who gave me this advice about cutting that hole:
First, I want a full kitchen-size drain, 3" hole. You can use a smaller 1-inch bar sink drain (1-inch plus?), but I want more flow. That smaller size, you MAY be able to cut with a saw drill (bit), a 1" hole cutter you attach to your drilll. However, this material is a BITCH to cut through, and since I'm going 3", it's not an issue anyway.
So I'm printing out a 3" circle on heavy card stock/paper, with a mark in the exact center of the crcle. I now cut that circle out.
From the UNDERSIDE of the sink, if you want your drain dead center, you simply draw 2 lines from the opposite corners to meet dead center. Poke a hole in the center of the paper circle, place it where the lines cross, and take a Sharpie and draw your circle.
Now DRILL a bunch of holes along that line, right ON the line. The drain has a very forgiving flange/lip. Now take snips and cut to make your hole.
The underside collar of the drain comes with a rubber gasket, and you use plumber's putty on that as you tighten that large "nut" to tighten the whole thing together securely.
After you've snipped the hole out though, before securing, it's a good idea to file it down a bit, to lose any big burrs. Basically, the gasket and putty on the underside fully seals it.
You then get a simple, cheap BENDABLE PVC pitting from HD that screws on to the collar of the drain (with some plumber's tape). The other end of that PVC feeds to a hole/fitting in the side of the TD that you screw a garden hose into for draining.
