Questions about HSK-A combi shell mill adapters

Does an HSK-A combi shell mill adapter need a pull stud?

No. The spindle clamps the HSK-A taper from inside, so there is no pull stud. For through-spindle coolant the holder takes an HSK-A coolant tube: 47CTHA050 for HSK-A50, 47CTHA063 for HSK-A63 and 47CTHA100 for HSK-A100.
