Zusammenfassung:In this cutting tool with a replaceable cutting head, a cutting head (11) including a cutting edge (12) is detachably attached to a tip end portion of a shaft-like tool main body (1) rotated around an axis (O) in a tool rotation direction (T). The tool main body (1) and the cutting head (11) are attached to each other when an abutment surface of the tool main body (5) on a tip surface of the tool main body (1) abuts and adheres to an abutment surface of the cutting head (17) on a posterior end surface of the cutting head (11). A recessed portion (16) and a projecting portion (4) able to be inserted into this recessed portion (16) are respectively formed on the posterior end surface of the cutting head (11) and the tip surface of the tool main body (1). The recessed portion (16) and the projecting portion (4) are formed to increase in width in a circumferential direction toward an outer peripheral side in a radial direction with respect to the axis (O).
