I totally disagree on the carbide is the only way topic.
With a HSS bit you can easily do one board and they are very easy to
sharpen.
You can drill without a drill stand, which self centers the drill.
The problem was centering of the drill.
carbide and a drill stand will NOT solve this problem, quite the opposite.
I do agree that carbide drills are much better for FR4 but it will not
solve
the problem for which help was needed.
