Composition: A multilayered coating with thick MTCVD TiCN-Al2O3-TiOCN layers applied over a carbide substrate specifically engineered for cast irons.
Application: Delivers consistent performance in high-speed machining of grey and ductile irons. The substrate design permits the insert to stay in the cut for a long time at high speeds with minimum deformation. The thick CVD coating and post-coat treatment provide superior wear resistance ensuring long and consistent tool life. Can be applied both in straight and lightly interrupted cuts.
Features and benefits
- Milling insert for cast iron and compacted graphite iron (CGI) machining.
- High-precision periphery ground insert.
- Indexabe milling insert with four cutting edges.
