Abstract
A cutting insert may include a base member including a plurality of tungsten carbide particles. In cases where a particle diameter distribution of the tungsten carbide particles is measured at intervals of 0.025 μm, the particle diameter distribution may include, as a maximum peak and a second peak, a first peak value that appears in a particle diameter range of 0.5-0.9 μm, and a second peak value that appears in a particle diameter range of 1.1-1.5 μm. A value of a particle diameter distribution frequency is larger than zero at a valley part where a value of the particle diameter distribution frequency reaches a minimum between the first peak value and the second peak value.
Claims5
A cutting insert, comprising:
- a base member comprising a plurality of tungsten carbide particles,
- wherein
- in cases where a particle diameter distribution of the tungsten carbide particles is measured at intervals of 0.025 μm, the particle diameter distribution comprises, as a maximum peak and a second peak, a first peak value that appears in a particle diameter range of 0.5-0.9 μm, and a second peak value that appears in a particle diameter range of 1.1-1.5 μm, and
- a value of a particle diameter distribution frequency is larger than zero at a valley part where a value of the particle diameter distribution frequency reaches a local minimum between the first peak value and the second peak value.
