Mitsubishi Materials | Precision Miracle® PVD Grade
Small Diameter Precision Profiling
The VCMT080202-MV VP15TF is a high-precision 35° rhombic turning insert, engineered specifically for small-diameter internal boring and intricate external profiling. Featuring Mitsubishi's proprietary VP15TF Miracle® PVD coating, this insert excels in Stainless Steel (ISO M) and Carbon/Alloy Steel (ISO P). The 0.2mm nose radius allows for ultra-fine finishes and sharp corner definitions while the MV chipbreaker ensures reliable chip evacuation in confined spaces.

Shop Compatible Boring BarsExpert Tip: Why Choose VP15TF Miracle Grade?
In precision work, built-up edge (BUE) is the enemy of surface finish. The VP15TF Miracle PVD coating is polished to a micro-smooth level, preventing material adhesion on the cutting edge. Compared to the US735 (CVD) grade, the VP15TF is sharper and more suited for finishing and semi-finishing where dimensional accuracy is the top priority.
MV Chipbreaker: The MV geometry is a "Medium-Volatile" design that balances chip breaking in soft stainless and hard steel, ensuring stringy chips are broken before they mar the workpiece surface.
