The freud router bits are made for “cabinet doors”, not “passage” doors. As a rule the coped mortise and coped tenon are 3/8” long which IMHO are barely long enough for a cabinet door, let alone a passage door.
I have hung hundreds of passage doors in my life. The only two jobs I did where the supplier of the passage doors were done with 3/8” tenons….......both projects the doors fell apart. Not to mention several people bringing the doors over to be re-built and refinished.
If you are indeed making “passage” doors then you might consider making two doors, 5/8” thick and then glueing the two slabs together…........seen it done and it works quite well. In the event you are making cabinet doors then disregard everything I wrote.
Good Luck
