DNMG150404-MS VP15TF
High-Precision Finishing | Anti-Work Hardening | Mirage PVD Technology
The Professional Choice for Precision CNC Turning
When looking for a Mitsubishi DNMG150404-MS price that matches performance, the VP15TF series stands alone. This insert is engineered to solve the most common issues in precision stainless steel finishing: surface tearing and dimensional drift.
VP15TF Grade (Mirage PVD Coating): This VP15TF grade for stainless steel uses Mitsubishi’s exclusive "Mirage" micro-layered PVD technology. It provides extreme surface hardness to resist abrasive wear while maintaining a low coefficient of friction. This is the ultimate PVD coated insert for tough materials like Inconel and 316L.
MS Chipbreaker (The Sharp Edge Specialist): The MS geometry is a "Medium-Sharp" design. It is significantly sharper than standard MA geometries, allowing it to "slice" rather than "rub." This is the secret to preventing work hardening in stainless steel, ensuring your finished part has a mirror-like surface and consistent dimensions.

VP15TF (The Precision Expert): Your first choice for CNC mass production where continuous cuts and high speeds are required. It offers the best surface finish and wear resistance.
US735 (The Interrupted Specialist): Switch to US735 only if your finishing pass involves heavy interruptions, holes, or unstable clamping. For 90% of precision finishing, VP15TF is the superior grade.
Searching for the best carbide inserts for precision finishing in 316 stainless steel? The Mitsubishi VP15TF vs US735 debate is settled when precision is key—the DNMG 150404-MS anti-vibration finishing insert is the industry gold standard. These long-life turning inserts for aerospace alloys are designed to maintain sharp edges under high heat. Buy genuine Mitsubishi DNMG 15 series inserts online here for guaranteed performance.

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.
