Mirage PVD Technology | Universal Material Coverage | MA Fine-Finish Geometry
The Universal Solution for Difficult Materials
VP15TF Grade (Mirage PVD Coating): The VP15TF utilizes a specialized PVD (Physical Vapor Deposition) coating known as "Mirage." This coating is exceptionally smooth and tough, specifically designed to prevent Built-Up Edge (BUE). It is the premier choice for gummy materials like 304/316 Stainless Steel and high-temp alloys, while remaining highly effective for general steel.
MA Chipbreaker (Precision Medium-Finish): The MA geometry features a positive rake angle that lowers cutting resistance. This is vital for 11-size inserts to prevent tool deflection. It provides stable chip breaking in both continuous and slightly interrupted cuts, ensuring a high-definition surface finish on smaller diameter workpieces.
0.4mm Radius (Tight Tolerance Finishing): The "04" (1/64") radius is built for precision. It minimizes radial pressure, allowing for tight dimensional control and a mirror-like Ra finish, making it perfect for the final pass on critical components.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DNMG110404-MA | 9.525 mm | 4.76 mm | 0.40 mm |

Recommended Cutting Parameters
*PVD grades like VP15TF perform best at moderate speeds with high lubricity coolant.
| Material Group | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 80 - 180 m/min | 0.05 - 0.20 mm/r | 0.30 - 2.00 mm |
| Alloy Steel / Carbon Steel | 100 - 220 m/min | 0.08 - 0.25 mm/r | 0.50 - 2.50 mm |

Shop DDJNR 11 HoldersPro-Tip: VP15TF vs. US735
VP15TF (The Versatile Expert): Use this for most stainless steel and alloy applications. It has a broader application range and much higher wear resistance at higher speeds.
US735 (The Tough Specialist): Switch to US735 only for heavy interrupted cuts or very low-speed machining in stainless steel. For general high-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.
