VCMT080202-MV VP15TF
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.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
