Abstract:

Provided is a cutting insert comprising side surfaces located between the upper surface and the lower surface thereof and having upper recesses extending to the upper surface, and also comprising separated upper cutting edges located along the line of intersection between the upper surface and each side surface and separated from each other by upper recesses. Each of the separated upper cutting edges has a first end and a second end and is tilted so as to approach the lower surface from the first end toward the second end. The separated upper cutting edges comprise first separated upper cutting edges and second separated upper cutting edges, and each first separated upper cutting edge and each second separated upper cutting edge are adjacent to each other. In a side view, the first end of the second separated upper cutting edge is located at a position above the intersection between a line extended from the first separated upper cutting edge and a line passing through the first end of the second separated upper cutting edge and parallel to the center axis of the cutting insert, and the position is the same as or below the position of the second end of the first separated upper cutting edge. Also provided are a cutting tool provided with the cutting insert and a method of cutting a material to be cut using the cutting tool.
