FWIW, I have multiple sizes of the half round variety, but they
look user-made.  I kind of assumed they were for enlarging a hole
to size in relatively thin stock, assuming one only had a bit for
a pilot hole.

This is the first photo I've seen of the tapered bit for wood, so
thanks for sharing it!  I have one that's basically a tapered spoon
bit; is that the form in the catalog?  Or would it likely be one of
the "specific tapered reamers" to which you alluded in your PS?  How
does one tell the difference?
