Bruce,

Use a drill bit's tip as a countersink tool?  Oh dear!

There are "real" countersink tools available that will
produce nice, even countersinking.  Inquire at a 
machine-tool supplier.  They come in a variety of
sizes amd have a smooth conical tip with a single
round hole forming the cutting surface.  The drill bit 
idea, unless done very carefully by hand, is certain to 
produce "three-cornered" countersinking.

I've thought of using flat or oval-head SS screws on 
my K2 but I'd first want to be certain the panels are 
thick enough to allow proper-depth countersinking.
