I have been very happy with a countersink bit I purchased from Lee Valley
Tool.

I like the continuous style. It has given me less tearout.

The single flute countersinks are excellent. The ones I own are made by the
Weldon Tool Company, I think bought mine at The Cutting Edge in Houston I
think. They work great in Aluminum as well.

Masking tape on the bit and care is excellent for depth control while
hand drilling (with or without electricity).
I actually own "real" depth stops and use tape more often than the
stops.

I bought a set of spiral, tapered bits with countersinks from Lee Valley
some 20 years ago. Flawless, never sharpened still in use today. (I did
break the tip off the #12 but it still works...sorta/kinda.)
The usual disclaimer applies: I'm Kanuckistani, like Robin Lee, other
than that we never had lunch.
Yes this is what I have been doing so far. My present uses have not
required precision. If I need to truly control then I would use a drill
press.
I normally use the countersink bit in a brace and bit. I drill a little,
test the hole against the screw head until I get the whole head to fit in
the hole.

With care or preferably the drill presses depth stop.
