<p>The disclosure relates to a cutting insert for a tool for machining a workpiece, comprising: two identical mutually opposite base surfaces, wherein at least a part of each base surface is orthogonal to a z-axis of the cutting insert, two identical mutually opposite main side surfaces which extend between the two base surfaces, wherein at least a part of each main side surface is oriented orthogonally to an x-axis of the cutting insert, and two identical mutually opposite secondary side surfaces which extend between the two base surfaces, wherein at least a part of each secondary side surface is oriented orthogonally to a y-axis of the cutting insert, wherein the x-, y- and z-axes are main axes of the cutting insert that are oriented orthogonally to one another, wherein between each one of the base surfaces and each one of the main side surfaces a main cutting edge is arranged, and wherein each main side surface has two diagonally opposite first segmental cutting edges, wherein each first segmental cutting edge adjoins a first end of the respective main cutting edge, wherein the main cutting edges and the first segmental cutting edges of each main side surface are each located in a cutting edge plane which extends orthogonally to the x-axis, wherein the first segmental cutting edges are each arranged on a first protrusion which is arranged on each of the secondary side surfaces and defines a first clearance angle.</p> |
