Drill_depth and Thread_depth parameters should be added to the hole_parameter_file.
Currently Creo Parametric M50 does not allow the user to define the drill depth and thread depth like can be done for the cbore depth.
My company has a set standard for drill and tap depths so it makes it hard to use this tool if we can't define them.
Another parameter that would be nice is Drill_Point_Angle. Not all tap drills are 118°.
this looks to be the same as this other idea.
Standard value of Drill_Point_Angl can be set with "drilled_hole_tip_angle" option.
This option in the config.pro is available with Creo 4 M060 and Creo 5.0.2.0
