  • Cutting tool insert and cutting tool insert holder
    Patent number: 9744597
    Abstract: A cutting tool insert includes eight identical cutting edges. Each separate cutting edge has a first cutting edge portion and a second cutting edge portion. A corner angle between the first cutting edge portion and the second cutting edge portion is within a range of 75 to <90 degrees. The first cutting edge portion and the second cutting edge portion have substantially the same length to provide a substantially equal cutting depth. As seen along the center axis of the insert a first angle within a range of 14+/?9 degrees is formed between a first imaginary line extending from the center axis to a corner point at the first side surface and a second imaginary line extending from the center axis to an adjacent corner point at the second side surface.
