[CAD_CAM_EDM_DRO] 15/16-16 bore size

That screw thread chart looks good. Does such a chart for metric
threads down to 0.4 exist. I'm having some difficulty making internal
and external 0.8mm threads. I don't have a metric set of drills and the
imperial set I have seems to have sizes that fall unequely in between
the "correct" size for internal threads. I'm also having problems with
external threads of the same size. Any tricks for dealing with these
small sizes.
