Best router bit for fine engraving?


I am getting ready to actually start cutting my full-size sheets of 1.5mm plywood for my airplane. However, there are scores of gussets which need to be cut (every joint has a gusset) and I am starting to label each of them in my CAD program.

I would like to set the size of these labels to 5mm in height - what bit would work best for this sort of fine engraving?


30 or 45 degree, even better if you get one with a .005" bit or something, but engraving in ply is tough.
