Centering with one of these center drill collets instead of a drill
chuck helps a lot:

Yeah, that looks good. I have some similar tailstock collets that I
inherited in the pile of tooling junk that my uncle passed along.
I've never used them, though.

Using it requires moving the tailstock since its overhang is much less
than a chuck's. It's fine for single parts but not so good if I need
to drill several to the same depth.
