Mirage PVD Technology | Multi-Material Excellence | MA Balanced Geometry
The Industrial Multi-Tool
VP15TF Grade (Mirage PVD Coating): The VP15TF grade is the pinnacle of Mitsubishi's PVD technology. The "Mirage" coating utilizes a micro-layered structure that offers extreme hardness combined with incredible adhesion. This prevents the "peeling" often seen in cheaper coatings and is specifically engineered to stop Built-Up Edge (BUE) in sticky 304/316 Stainless Steel and aerospace alloys.
MA Chipbreaker (The Versatile Standard): The MA geometry is the industry’s most balanced chipbreaker. It features a medium rake angle that is sharp enough to cut through gummy stainless but strong enough to handle the scale on alloy steel. It ensures stable chip evacuation, protecting your workpiece from scratches and reducing machine downtime.
0.8mm Radius (High-Volume Stability): The "08" (1/32") radius is the perfect compromise for 90% of turning applications. It provides high edge security for roughing passes while still leaving a smooth, commercial-grade surface finish during finishing passes.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DNMG150408-MA | 12.70 mm | 4.76 mm | 0.80 mm |
| Imperial | DNMG432-MA | 1/2" | 3/16" | 0.0315" (1/32") |
Recommended Cutting Parameters
*VP15TF is universal. For best results in Stainless, maintain consistent feed to avoid work hardening.
| Material Group | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 100 - 200 m/min | 0.10 - 0.35 mm/r | 0.50 - 3.50 mm |
| Alloy Steel / 4140 | 120 - 250 m/min | 0.15 - 0.40 mm/r | 1.00 - 4.00 mm |

Shop DDJNR 15 HoldersPro-Tip: VP15TF vs. US735
VP15TF (The High-Speed Universal): Best for CNC machines where high RPM and continuous tool life are required. It handles everything from steel to exotic alloys.
US735 (The Interrupted Specialist): If you are turning a workpiece with deep keyways or perform very heavy-duty roughing in stainless steel, switch to US735. For all other precision CNC work, VP15TF is the superior choice.

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.
