BTW, an end mill or flat bottom drill would work fine. I'd choose a
diameter with minimal clearance for the screw head diamater.

I have done this by drilling with an ordinary drill until well started
then switching to an end mill - less tendency to wander at the start.

The original post brought to mind a wall chart I saw once. It had pictures
of lots of different cutting tools and the name(s) for each of them. Maybe
someone else has seen one like that and perhaps knows where to get one. If
so, sign me up.
