Applications
This milling insert is strictly tailored for the secure face and shoulder milling of gray cast iron and nodular cast iron components. The strong cutting edges handle demanding cutting conditions well and support efficient workflows in both serial production and single-part manufacturing.
Special features
The heat-insulating CVD coating effectively shields the carbide core from rapid wear at elevated cutting speeds. The combination of a tough substrate and a well-designed cutting geometry promotes smooth operation, minimizes vibrations, and creates a clean surface finish on the workpiece.
