Operating Guidelines
Follow these best practices to maximize insert life and machining quality:
- Standard toolholder setup with 93° approach angle provides best versatility.
- Maintain consistent depth of cut above 0.5mm to engage chipbreaker effectively.
- Use flood coolant for steel; air blast acceptable for cast iron applications.
- Index insert when flank wear reaches 0.3mm or when surface finish degrades.
- Store inserts in original packaging away from moisture and corrosive environments.
Toolholder Compatibility
Compatible with standard ISO toolholders designed for TNMG inserts with 16mm shank systems. Recommended holder families:
- External Turning: MTJNR/L, DTJNR/L, STGCR/L (90°, 75°, 45° approach)
