The other thing is the cutting length of the bit.
I'm a bit confused as to the exact difference between a round nose and a core box bit.
For lettering I think the cutting length needs to be a little longer than the radius... the major diameter should be below the surface of the sign, but just barely.
If the cutting length is just the same as the radius you'll undercut the surface.
