SNMG120408-MA VP15TF
Mitsubishi Materials | Miracle PVD Coating for Universal Performance
The Mitsubishi SNMG120408-MA VP15TF is a premium indexable carbide insert designed for maximum versatility across multiple materials. Powered by the VP15TF Miracle PVD coating, this insert is the industry's go-to for universal turning of steel, stainless steel, and cast iron. It is particularly effective for small-batch CNC jobs where tool changes between materials need to be minimized. The 0.8mm radius combined with the MA chipbreaker provides a perfect balance of edge strength and surface finish quality.

VP15TF Miracle Coating
The VP15TF grade is a "Miracle" PVD (Physical Vapor Deposition) coated carbide. Its nano-layered structure provides extreme hardness and excellent adhesion resistance. It is the definitive grade for suppressing built-up edge (BUE) in stainless steel turning and prevents thermal cracking in interrupted cutting across ISO P, M, and K material groups.
MA Medium-Cut Chipbreaker
The MA chipbreaker is a versatile, double-sided geometry optimized for medium-duty cutting. It features a land designed to reduce cutting forces while ensuring reliable chip control. For the CNC operator, this translates to stable chip breaking in both carbon steel and stringy stainless steel alloys, protecting the workpiece and machine spindles from vibration.
