摘要： Provided are a cutting insert and a tool holder on which the cutting insert is provided. The cutting insert includes a circular upper surface, a circular lower surface, a cylindrical lateral surface for connecting the upper surface and the lower surface, an upper cutting edge formed between the upper surface and the lateral surface, a lower cutting edge formed between the lower surface and the lateral surface, and a plurality of rotation-preventing parts provided at the lateral surface so as to prevent the cutting insert from rotating with respect to the tool holder. Each rotation preventing part includes an inner curved surface recessed toward the center of the lateral surface and convexly rounded so as to form concentric circles in conjunction with the lateral surface, and a stepped rotation-preventing surface parallel to the axial direction of the insert and connecting the inner curved surface and the lateral surface.

摘要： An insert in which a cutting edge is formed only between an upper surface and a side surface. The insert comprises: three or more corners along a perimeter; a main cutting edge formed on an edge between an upper surface and a main side surface, and a sub cutting edge formed on an edge between the upper surface and a sub side surface, wherein the main cutting edge and the sub cutting edge are placed in succession between the corners; and a flat lower surface. The main cutting edge forms an inclination angle such that a height decreases gradually in a direction toward the sub cutting edge. The main side surface is formed by a first end main side surface and a second end main side surface. The sub side surface is formed by a first end sub side surface and a second end sub side surface.

摘要： A technical object of the present disclosure is to provide an insert, which can maintain rigidity thereof regardless of a clearance angle of a clearance surface that forms a circular cutting edge. To this end, the insert according to the present disclosure includes a circular upper surface, a circular lower surface, and a clearance surface portion connecting the upper surface and the lower surface. The clearance surface portion is divided into first and second clearance surfaces along a circumference thereof, by a first wave line that forms a waveform of valleys facing the lower surface and mounts facing the upper surface.

摘要： A cutting insert and a cutting tool having same are provided. The cutting insert includes an upper surface, a lower surface having a flat surface, side surfaces connecting to each of the upper surface and the lower surface, and cutting edges being formed by the upper surface and the side surfaces. A first cutting edge among the cutting edges is inclined downward. A major side surface among the side surfaces comprises a first major side surface connected to the upper surface so as to constitute the first cutting edge, and a second major side surface connected to the first major side surface and the lower surface. The first major side surface has a reversely positive surface, and the second major side surface has a reversely positive surface or a negative surface, and a minor side surface among the side surfaces has a positive surface or a negative surface.
