Claims

[Scope of utility model registration request]

Along the circumference of the tip of the cutter body,
The cutting edges located on the outer circumferential side are respectively used as the main cutting edges, and the throw-away tips arranged on the distal end side of the cutter body and the throw-away tips arranged on the proximal end side of the cutter body are arranged alternately. In the indexable milling tool, which is detachably attached to the throw-away tip, the throw-away tip has a main cutting edge formed on the ridge opposite to the upper surface thereof, and a lower surface serving as the seating surface from the main cutting edge. It has a rectangular plate shape with a rake face formed on the side surface extending to the main cutting edge, and the width dimension between the rake faces at the center of the main cutting edge is the tip of the cutting edge of the main cutting edge. A throw-away milling tool, characterized in that it is formed with a convex curved surface that is larger than the width dimension between each of the rake faces at the rear end of the cutting blade.
