I would think ideally a 1/4" (6.35mm) capacity keyless chuck on the end of
a
middle size screw driver would be ideal for this sort of work. Somebody
must have made one already. Maybe a 3/8 or 1/2 would be handy, but I
usually find myself dealing with this on the smaller bits and reamers.

I know them as a pin vise.

Try this search for some examples:

Watch their suggestions along the edges while clicking on a few. That
search doesn't find all they have to offer...

Funny you should bring this up. Just ordered this one:

YES!!! I may get two or three or four of them so I can leave the 1/16th
and 1/8th bits I use all the time on my tackle making bench chucked up and
ready to go. Maybe another on the back work bench, and one on the assembly
bench in the machine room.
