DCMT11T302-MV VP15TF
Precision Finishing Specialist | Miracle PVD Technology | 0.2mm Anti-Chatter Radius
Superior Control for Difficult-to-Cut Materials
VP15TF Grade (Miracle PVD Coating): The VP15TF is Mitsubishi’s world-renowned PVD-coated carbide. Engineered with the "Miracle" coating (Al-Ti-N), it provides a perfect balance of toughness and hardness. It is specifically effective at preventing Built-Up Edge (BUE) when machining gummy materials like 304/316 stainless steel and maintains sharp edges in heat-resistant super alloys.
MV Chipbreaker (Micro-V Precision): The MV geometry is a master of light-duty finishing. Its sharp rake angle slices through material with minimal cutting force, ensuring that heat is carried away by the chip rather than the workpiece. It is designed to provide excellent chip breaking even at extremely shallow depths of cut.
0.2mm Radius (Universal Precision): The sharp "02" (1/128") nose radius is critical for reducing radial cutting pressure. This makes it the ideal selection for machining long, slender shafts or components with thin walls where vibration (chatter) is a constant risk.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT11T302-MV | 9.525 mm | 3.97 mm | 0.20 mm |
| Imperial | DCMT32.50.5-MV | 3/8" | 5/32" | 0.0078" |
Recommended Machining Parameters
*VP15TF thrives with consistent coolant flow. Adjust feeds carefully to protect the 0.2mm sharp tip.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 100 - 180 m/min | 0.03 - 0.10 mm/r | 0.10 - 0.80 mm |
| Carbon/Alloy Steel | 120 - 220 m/min | 0.04 - 0.12 mm/r | 0.10 - 1.00 mm |

VP15TF (PVD): Best for multi-material workshops. It is much tougher than cermet and survives light interruptions or vibration significantly better.
NX2525 (Cermet): Use NX2525 only when your setup is extremely rigid and you are machining carbon steel to a mirror finish. VP15TF is the "safer" and more versatile choice for most CNC operators.

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.
