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 whose two surfaces forming a wedge are brought into contact with the throw-away tip and the tip mounting seat, and a wedge member that is integrally formed with the wedge member and is disposed within the tool body. a clamp member that is movable toward the axis of the tool body, which is the direction of action of the wedge, and a wedge shaft that has a convex portion formed at its tip; and a wedge shaft that moves in a direction that intersects the clamp member. The protrusion at the tip of the wedge shaft is inserted into the recess formed on the outer periphery so as to move forward and backward in a direction perpendicular to the direction of movement thereof, and both ends protrude outside the tool body. A throw-away milling tool comprising: an insertion/removal shaft; and a biasing member that biases the wedge member toward the axis of the tool body.
