Then you spin the punch section onto the draw stud from under the sink and spin it up tight to the bottom of the sink. Then you go up top and use a ratchet tool and socket of the correct size to tighten the ball bearing nut. This tightening draws the punch up into the metal and makes a perfect hole by literally PUNCHING OUT a circle.
This is great on metal studs or other thin metals, but can cause an indent in thicker metals (such as thick guage sink metal) that can be an issue if you aren't careful. I have used both hole saws and punches to make additional holes in sinks. The hole saws were messy and noisy and if you slip..you own the sink...*OUCH...but overall this made a really nice hole. The punch was also a bit noisy/messy as I had to drill a couple holes to get the proper hole size for the draw stud, and it created a bit of a dent at the sides of the hole, but again, made a nice hole in the end. I would recommend ewither way.
Hope that all made sense...
