Claims

[Scope of Claim for Utility Model Registration] A throw-away type rotary tool in which a throw-away tip with a cutting edge is removably attached to a concave tip mounting seat formed on the outer periphery of the tip of a tool body via a clamp mechanism. In the cutting tool, the clamp mechanism includes a wedge member provided between the throw-away tip and the tip mounting seat with two faces facing each other that are inclined relative to each other to form a wedge, and the wedge member includes: a wedge shaft that is integrally formed and is movable in the radial direction of the tool body, which is the acting direction of the wedge of the wedge member, and that has a first engaging portion formed on its outer periphery; The insert is movable along the axial direction of the main body, and has a second engagement part formed thereon that is slidably engaged with the first engagement part of the wedge shaft in a direction intersecting the direction of movement. A throw-away milling tool, characterized in that one of the first and second engaging portions is a key, and the other is a keyway that engages with the key.
