An internal cavity cutting tool assembly includes a tool body, a tool hanger, and a bearing assembly. The tool hanger body has a through-bore that is adapted to receive the bearing assembly. The tool body has first and second body portions, each having an arbor bore, a cutting face having a plurality of indexable cutting inserts, and a bearing support surface. The bearing support surface of the second tool body portion is also received by end of the through-bore, such that the bearing support surfaces of the tool body portions oppose each other within tool hanger body. An arbor drive shaft and a support are operatively inserted though openings in a workpiece and through the arbor bore of the tool body. The arbor drive is retained in a milling device to operatively rotate the tool body assembly while precisely locating the tool hanger assembly, thereby sweeping the cutting inserts against the portions of the workpiece to be cut.
