I need to find a flat bottom countersink for SHCS. Do I use an end mill? Is there a drill countersink combination that will give me the flat bottom? I have tried McMaster and MSC and can't find anything. Thanks in advance

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.
