The insert grade is primarily selected according to the component material, the type of application and the machining conditions.
- Component material (ISO P, M, K, N, S, H)
- Type of application (F, M, R)
- Machining conditions (good, average, difficult).
The insert geometry and insert grade complement each other when being applied; for example, the toughness of an insert grade can compensate for
lack of strength in an insert geometry.
