If these were silver jump rings the way to do it would be to split the rings
with a jewellers saw, cutting lengthwise along the dowel (ie with the
mandrel still in the rings). You do all the of the rings-to-be coiled on the
mandrel with one cut. BTW I cut mild steel (and worse) with a jewellers saw
all the time. I suppose you might use a hacksaw, but my bet is that the
jewellers saw would be enough easier to control that it ends up being
faster.

Hand tools are very efficient for some operations.

I want to cut them with a jewelers slotting saw. I've found the blades
all over the place but can't find an arbor that will fit into a 3/8 inch
drill chuck. Where do I get one?

DON'T DO IT!
I did this as a kid and damn near cut my thumb off.
