VP15TF Miracle Grade Technology
The VP15TF grade is a carbon-rich AlTiN-based PVD coating that creates a smooth surface to prevent built-up edge (BUE). This material technology is ideal for stainless steel turning and alloy steels, providing a substrate that is tough enough to resist micro-chipping while maintaining a high hardness for wear resistance.
Reinforced Corner Strength
Featuring a 0.8mm nose radius, this indexable turning insert is built for semi-roughing to medium finishing. It allows for higher feed rates and provides significantly more stability in interrupted cuts compared to 0.4mm alternatives, ensuring reliable chip evacuation in tough materials.
