摘要 In the present invention, in a milling cutter (10), cutting tips (38) are affixed to a plurality of attachment seats (28) disposed along the peripheral direction at least at the end surface side of the outer periphery of a cylindrical tool main body (11), and a supply hole (13) for fluid flow-through is provided to the center of the tool main body (11) extending in the axial direction thereof. The milling cutter (10) is provided with: a flow-through concavity (19) that interconnects with the supply hole (13) and is recessed coaxially with the end surface of the tool main body (11); and a lid member (31) affixed superposed to the flow-through concavity (19). Between the flow-through concavity (19) and the lid member (31) are provided a plurality of flow-through holes (25a) that interconnect the supply hole (13) and the vicinity of the plurality of cutting tips (38) at the outer periphery of the tool main body (11).
