AH7025

AH7025 uses the latest coating technology of a
nano-scale multi-layered AlTiN PVD coating with
high Al content, featuring
- Coating hardness increased by 20%
- A multi-layered coating structure impedes
micro-crack propagation, reducing insert failures
- Enhanced adhesion strength between the coating
and carbide substrate layer
High wear and fracture resistant carbide substrate for
optimal grooving performance
