Edi,

A countersunk hole is simply a normal right cylindrical through-hole with an
additional right conical section removed for accepting a flat head screw.
The cone angle is typically 82 or 100 degrees. The diameter of the smaller
end of the conical section is the same size as the hole and the diameter of
the larger end depends on both the angle and the thickness of the material.
The creation of a countersunk hole is performed using a special countersink
drill bit or a drill bit and angle end mill in combination.
