Something like this:

And yes, you could quite easily get the 0.05mm tolerance.

Nice job. I thought of making a holder to replace the lantern
toolpost and take a HSS tool bit at 90 degrees, and not worry about
any relief. For longer cuts, though, I can see that having the 5
degrees clearance makes a lot of sense.
