DNMG150408-MS VP15TF
Medium Turning Mastery | Anti-Work Hardening | Mirage PVD Technology
Superior Performance in Gummy Materials
When looking for a competitive Mitsubishi DNMG150408-MS price, you are investing in a tool designed for the long haul. This insert is engineered to address the thermal and mechanical stresses of modern CNC Turning.
VP15TF Grade (Mirage PVD Coating): This VP15TF grade for stainless steel features the proprietary "Mirage" micro-layered PVD technology. It provides a unique balance of extreme surface hardness and thermal stability. It is recognized as a premier long-life turning insert for aerospace alloys and 316L stainless steel, where heat dissipation is critical.
MS Chipbreaker (Medium-Sharp Geometry): The MS geometry is a sharp-edged design that minimizes cutting resistance. By slicing the material cleanly, it is highly effective at preventing work hardening in stainless steel. This ensures that the surface remains machinable for secondary operations and significantly improves tool life.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DNMG150408-MS | 12.70 mm | 4.76 mm | 0.80 mm |
| Imperial | DNMG432-MS | 1/2" | 3/16" | 0.0315" (1/32") |
Recommended Cutting Parameters
*The 0.8mm radius allows for higher productivity. Maintain high coolant flow to manage chip heat.
| Material Group | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| 304/316 Stainless Steel | 110 - 200 m/min | 0.12 - 0.35 mm/r | 0.80 - 3.50 mm |
| Nickel Alloys (Inconel) | 25 - 55 m/min | 0.10 - 0.25 mm/r | 0.50 - 2.50 mm |
Pro-Tip: VP15TF vs. US735
VP15TF (The Continuous Speedster): Best for stable CNC turning. It offers superior wear resistance at high RPMs and is the primary PVD coated insert for tough materials during continuous cuts.
US735 (The Interrupted Specialist): Switch to US735 only if your medium turning involves heavy interruptions or unstable clamping. For 90% of stainless steel applications, VP15TF provides higher productivity.
Looking for the best carbide inserts for medium turning in 304 stainless steel? The Mitsubishi VP15TF vs US735 comparison proves that for stable CNC operations, the DNMG 150408-MS reliable medium turning insert is the professional choice. This PVD coated insert for tough materials provides a superior surface finish and prevents built-up edge. Buy genuine Mitsubishi DNMG 15 series online for guaranteed CNC production efficiency.

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.
