Guess I'd like to see a step where the hole was properly deburred AND the use of a flanged "hub" (as in conduit adapter) which fits tight to the outside of the box and is threaded inside the box rather than the implication in the video that you just slide a conduit loose into the unburred hole and you're done. Otherwise, nice video and good step bit.

sounds good doesn't work

Why post the vid if I can't buy the tool???

I just drilled a third hole through a very thick 3/16" (5mm) Kraus stainless steel sink (very different from the sink in this video) I used a tungsten carbide tipped hole saw in a 12v Bosch drill/driver. Used water for cooling. Took a little effort but it drilled out cleanly. To remove any burrs I used an 8" half round 'basterd cut' (fine) file. Thought I was going to have to go over it with sandpaper, but it's smooth enough. I used a 1-3/8" (35mm) hole saw. Hope this helps. It answers the questions I had and it worked well.

Video sucks
