I have a set of Greenlee knockout punches used for, obviously, creating
holes for electrical conduit. I've cut holes in some fairly thick metal
over the years, and these tools have never flinched.
I'm wondering if they're sturdy enough to create a hole in a stainless
steel sink. I'm not sure of the gauge. It's not the lightweight
super-thin junk you find at home centers for $50, but it's not
commercial, either. I'd hate to ruin either the sink or the tools.
I'm not squeamish, and I'm reasonably sure this will get the job done,
but if anyone knows (maybe the hard way) why I shouldn't try this,
please chime in.
