TNMG160408-MS VP15TF
Mitsubishi Materials | The Universal Miracle Coated Standard
Product Overview
The Mitsubishi TNMG160408-MS VP15TF is a high-performance PVD Miracle Coated carbide insert, engineered for versatility across a wide material spectrum. The VP15TF grade is the industry benchmark for stainless steel turning and heat-resistant alloys. As a premier long-tail precision tool, the MS chipbreaker ensures superior chip control and reduces cutting resistance during CNC machining of austenitic stainless and carbon steels.

VP15TF Miracle Technology
The VP15TF grade utilizes Mitsubishi's proprietary PVD Miracle coating, offering exceptional adhesion and heat resistance. This reduces built-up edge (BUE) in gummy materials and provides long-lasting durability in an indexable turning insert, especially when machining SUS304 or SUS316.
MS Chip Control Logic
The MS chipbreaker is a medium-light geometry designed for stability. Its sharp cutting edge reduces work hardening on the workpiece surface and promotes excellent chip evacuation, making it ideal for precision finishes in CNC turning applications.
Recommended Cutting Parameters

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.
