Product video
Features
- High hardness and oxidation resistance
- Outstanding tool life with efficient machining of difficult to cut stainless steels and steels
- Improved coating bonding force and surface smoothness
Prevents BUE, common when cutting stainless steels, and achieves stable machining
Tooling application
For stainless steels and steels
Front turning / Back turning / Grooving / ID boring / Cut off
Coating wear and oxidation chart
NTK vs. Competitor (Cut-off edge)
- [ Cutting conditions ]
- Material : SUS304 φ11 vc=80m/min f=0.03㎜ /rev after 200 pcs.
Measurement (Scratch test on coating layer)
- NTK's new PVD coating technology improved the bonding force and smoothness on ST4.
It eliminates BUE issues and improves insert performance.
