A face mill holder is chosen by the cutter, not by the machine: the arbor diameter and the retaining screw have to match the cutter you already own. Mongtec builds both the metric DIN 6357 range and a full inch range — which matters, because a shop running inch cutters cannot use a metric arbor and most Taiwanese suppliers only publish metric.
