bit for jewelry box budget hinge

[Kevin Jenness]

I am considering ordering some of Ian Hawthorne's budget side rail hinges which require an odd size metric bit. https://www.fineboxhardware.com/product/jewelry-box-hinge-budget-gold/ I'm looking for a 9mm downcut or straight bit with a 1/4", 3/8", 1/2" or 10mm shank. I've looked at Onsrud, Vortex, Freud, CMT, Whiteside and I forget what else. Any suggestions? Has anyone used these hinges?

Here's one on Amazon https://www.amazon.com/Trend-C012bx1-Flute-Cutter-Diameter/dp/B00466VY0Y

For reference, 9 mm (0.354331") is a whisker from 23/64" (0.359375") also. Not that is easy to find in a router bit!!

Kevin, are you cutting with a CNC? If so, you can use a smaller diameter tool and pocket it out. If you truly need a 9mm tool, check with UK or EU based tool sellers to see if they have anything available.
