We have had some success in tapping form drills, reamers and port cutters.
Tap the tool like you would an endmill.
Add the cutting depth per side and use that value as the Width of Cut (Ae) in Current Conditions.
Use the hole depth as Depth of Cut (Ap) in Current Conditions.
Make sure you have the right number of teeth in Tool Details. Use the major diameter of the cutter for the tool diameter.
Use the Dashboard to find the best speed within the SFM limits from the tool manufacturer. Use the in-feed data supplied the manufacturer.
