Claims

[Scope of utility model registration request]

In the indexable milling tool, the cutting blade tip is placed on the chip mounting surface in the cutting blade storage groove of the cutter body via a supporter, and the cutting blade tip is fixed by a fixing means. a sheet member comprising a tip positioning wall portion interposed between the tip mounting surface of the cutter body and the seating surface of the cutting edge tip and against which the side surface of the cutting edge tip in the central axis direction of the cutter body is brought into contact; and an axial support member that supports the side surface of the cutting edge tip in the axial direction of the cutter body, and these sheet members and axial support members are made of cemented carbide or a powder-sintered alloy such as cermet or ceramic. A throw-away milling tool characterized in that the sheet member and the axial support member are removably attached to the cutter body by the same fixing means.
