A machining head (10) for a machine tool includes a spindle unit (20) to which a tool is attachable and a support head component (30, 60) that includes an index mechanism for indexing an angular position of a spindle (21). The index mechanism includes a drive motor (33, 63) supported by a bearing (35, 65) within the housing (31a, 61) of the support head component (30, 60) and a rotary joint (37, 67) disposed concentrically with the bearing (35, 65) and the drive motor (33, 63). The bearing (35, 65) is disposed within a range occupied by the drive motor (33, 63) in an axial direction of a support shaft (32, 37b, 62, 67c), and the rotary joint (37, 67) is disposed within the drive motor (33, 63) in a radial direction thereof.
