Claims

[Claims for Utility Model Registration] A tip mounting seat formed at the tip corner of the tool body has a polygonal flat plate shape as a whole, and a cutting edge consisting of a cutting edge, a rake face, and a flank face at the tip of the corner. A cutting tool in which a throw-away tip is mounted, the throw-away tip having a blade width dimension where the thickness of the cutting edge portion is thinner than the thickness of the main body. A first reference position is defined as a point that passes through the first reference position, is perpendicular to the bottom surface of the tool body, and intersects with the flank surface, and a second reference position is defined as a point that passes through the first reference position, is perpendicular to the bottom surface of the tool body, and intersects with the flank surface. A point located on the tip side of the tool body is defined as a third reference position, and the cutting edge portion is formed in a range extending toward the tip side from a line connecting the first reference position and the third reference position. A cutting tool characterized by being placed on.
