Material Science & Chip Control
VP15TF Grade: The "Miracle Coated" PVD carbide substrate offers a perfect balance of toughness and wear resistance. It prevents built-up edge (BUE) on stainless steels and remains stable under high thermal loads when cutting titanium or nickel-based alloys.
MA Chipbreaker: Designed for Medium-range cutting, the MA geometry features a specialized rake angle that ensures smooth chip evacuation at varying depths of cut, reducing vibration in long-reach CNC turning applications.
