DCMT070204 VP15TF
Miracle PVD Coating | Multi-Material Specialist | 55° Precision Profile
The "Miracle" Grade for Mixed-Material Shops
VP15TF Grade (PVD Miracle Coating): The VP15TF is Mitsubishi’s most versatile PVD-coated grade. It features the "Miracle" coating—a high-adhesion Al-Ti-N layer that provides extreme oxidation resistance. Unlike thick CVD coatings, this PVD layer is thin and uniform, keeping the cutting edge ultra-sharp. It is the gold standard for machining Stainless Steel, Carbon Steel, and Tough Alloys (M10-M30, P10-P30, S10-S25).
DCMT Geometry (Precision Profiling): The 55-degree diamond shape with a 7-degree relief angle is the ultimate geometry for internal boring and external profiling. The positive rake design reduces cutting forces, making it perfect for small-diameter parts or light-duty CNC lathes.
0.4mm Radius (The Finisher): The "04" radius is designed for precision. It provides excellent surface finishes and maintains dimensional accuracy by minimizing radial pressure, which effectively eliminates chatter in slender workpieces.

Recommended Cutting Parameters
*VP15TF is designed for versatility. Use coolant when machining stainless for maximum tool life.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 80 - 180 m/min | 0.05 - 0.15 mm/r | 0.20 - 1.20 mm |
| Carbon/Alloy Steel | 120 - 250 m/min | 0.05 - 0.20 mm/r | 0.20 - 1.50 mm |

Shop 07 Series HoldersPro-Tip: VP15TF vs. UE6020
VP15TF (PVD Generalist): Your first choice for Stainless Steel or mixed batches. It stays sharper and prevents welding of gummy materials.
UE6020 (CVD Specialist): If you are turning Carbon Steel only in high volumes, switch to UE6020. The CVD coating will provide better tool life at higher speeds in steel.

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.
