VP15TF Miracle Grade
The VP15TF grade combines a high-toughness micro-grain carbide substrate with Mitsubishi's Miracle (Al-Ti-N) PVD coating. This grade provides industry-leading thermal stability, which is vital for milling gummy materials like 304/316 stainless steel. It effectively prevents built-up edge (BUE) and ensures long-lasting edge sharpness in dry or wet machining.
-M2 Chipbreaker Logic
The -M2 medium-duty chipbreaker is designed for versatility. It provides a balanced geometry that reduces cutting resistance while maintaining a reinforced edge to withstand impact during high-feed milling. This ensures a consistent thread surface finish and high dimensional accuracy in 3D pocketing and ramping operations.
