A Vee machining center employing two distinct non-captive tool retaining means which are, each, operable to retain a tool in substantially the same position as a function of the tool releasing movement of the other. One of the retaining means consists of the usual flexible drive belt for rotating the tool while the other comprises a mechanical gripper providing temporary support for the tool during tool interchange. Two distinct, alternately usable power sources provide two distinct speed control ranges for the machining center.
