Nicely done. One small criticism.

End mills should not be held in drill chucks. I know, everyone does it.
But your articles are aimed at newbies.
End mills are as hard or harder than the drill chuck jaws. This can and
does do damage, especially if it slips.
The right tool for this operation/in this machine/ is a piloted
counterbore. They have the advantage of a ofter shaft and a removable
cutter. This is handy for reverse counterbores where the tool is pulled
into the work from the opposite side.
On the other hand, if the machine you were using was a mill, and it had
the right holder for the endmill, your operations would be appropriate.
