(Slight) Buyer's Regret: Dowel-forming Dies

4-die set. The plate has screw holes
in case you want to anchor it permanently,
but it isn't really necessary.

The die in use (cutaway)
I bought a set of Veritas metric dowel formers from Lee Valley (for more money than I really wanted to spend, but it's done now).

They're good quality, but for the money I think you'd be better getting a manufacturing engineer to drill and heat-treat a ¼" plate with a range of hole sizes.

The separate dies are all very well, but if you're hammering dowels you get much cleaner results if you can take the dowel down in 1 or 0.5mm increments, and with this system you have to swap out the die each time. Also, there are only 12, 10, 8 and 6mm dies in the set, and a 2mm step is too much between each step really. You can hammer the dowels through OK, but it has a tendency to tear the dowel surface instead of shaving it, especially in an open-grained timber like oak.
