Input on the best bits for countersinking will be appreciated.
The ones I have are tearing up the surface grain real bad (and they're

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.

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.

Dave
How would you control depth of cut with that style?

With care or preferably the drill presses depth stop.

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.

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.

You might try checking the edge on the ones you have, and sharpening if
necessary.
