VP15TF Miracle Grade
The VP15TF grade is a universal micro-grain carbide substrate paired with the Miracle (Al-Ti-N) PVD coating. This grade is renowned for its high resistance to built-up edge (BUE) and thermal cracking. It is specifically optimized for milling gummy materials like 304/316 stainless steel where heat management is critical.
-MP Chipbreaker Geometry
The -MP medium-cut chipbreaker features a 3D molded rake face that effectively reduces cutting forces and manages chip formation. This prevents chip recutting and improves surface finish quality. It is ideal for CNC milling operations requiring stable performance across varying depths of cut.
