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 clamping mechanism includes a wedge member provided between the throwaway 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; A second engaging portion is provided to be movable along the axial direction of the main body, and is formed in a direction intersecting the direction of movement with which the first engaging portion of the wedge shaft is slidably engaged. and a biasing member that biases the wedge member toward the inner peripheral side of the tool body, and one of the first and second engaging portions is a key. A throw-away milling tool characterized in that the other end is a keyway that engages with the key.
