Claims

[Claims for Utility Model Registration] (1) A plurality of throw-away tips, each of which has a cutting edge on the outer periphery as the main cutting edge, are provided on the outer periphery of the tip of the cutter body, and the main cutting edges of each other are rotated. In the throw-away milling tool, which is connected in the axial direction of the cutter body in its locus and is removably attached with a positive axial rake angle, the throw-away tip has opposite ridges on its upper surface. A main cutting edge is formed on the main cutting edge, and a rake face is formed on the side surface from the main cutting edge to the lower surface serving as the seating surface. A throw-away characterized in that the width between the rake faces at the center of the blade is larger than the width between the rake faces at the tip and rear end of the main cutting edge. Type milling tool. (2) The scope of the utility model registration claim, which is characterized in that the positive axial rake angle of the throw-away tip attached to the tip of the cutter body is set smaller than the positive axial rake angle of other throw-away tips. The throw-away milling tool according to item 1.
