NNMU200708ZEN-MP VP15TF
Mitsubishi Materials | Double-Sided High-Performance Milling Insert
The Mitsubishi NNMU200708ZEN-MP VP15TF is a premium indexable milling insert designed for high-efficiency face milling and shoulder milling. Featuring a unique double-sided design, it provides multiple cutting edges to maximize cost-efficiency without compromising tool rigidity. The -MP chipbreaker is engineered for medium-range cutting, offering a perfect balance between edge sharpness and strength. Combined with the legendary VP15TF Miracle PVD coating, this insert is the industry's "go-to" solution for machining stainless steel, carbon steels, and heat-resistant alloys.

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.

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.
