Engraving bit for a mill

You could try your nearest friendly Dremel tool supplier (eg Bunnings), except they'll have smaller than 1/8" shanks (which shouldn't present a major problem if you're able to use a collet or pin chuck for the job). 3.0 mm most likely.

Dremel have a couple of sizes of milling cutters for engraving as well as diamond tools (for glass, ceramics, etc).
