Hi All,
        Like many people, I like to use two large 12 inch salad bowls as a
top terminal.  For my new one, with built in current sensors, I had to drill
5 holes through the bowls.  WOW! was it hard.  The stainless steel in those
things must be very high in chromium content or something.  I trashed a
number of nice drill bits.  The titanium nitride bits work for a moment then
just slide on the surface.  If anybody has any better ways to drill nice
holes through this stuff, I would love to know about it.
