DNMG150608-MA VP15TF
Heavy-Duty Stability | Mirage PVD Technology | MA Universal Geometry
Engineered for Thermal Rigidity
VP15TF Grade (Mirage PVD Coating): The VP15TF is Mitsubishi’s premier PVD-coated grade for difficult-to-cut materials. Featuring the legendary Mirage Technology, this nano-structured coating provides an ultra-smooth surface that resists chemical welding. It is the definitive solution for stopping Built-Up Edge (BUE) when machining 304/316 Stainless Steel and aerospace alloys.
MA Chipbreaker (Medium-Cut Mastery): The MA geometry is designed for medium turning operations. It balances a sharp cutting action with high edge security. This chipbreaker is optimized to curl and break chips effectively even in gummy materials, ensuring stable chip evacuation and preventing surface marring.
6.35mm Thickness (The "06" Stability): Unlike standard 4.76mm inserts, the 1506 series features a 6.35mm body. This extra thickness acts as a massive thermal sink, absorbing the heat generated at the cutting edge and dissipating it through the tool holder. This prevents the insert from "softening" during heavy-duty, long-duration cuts in alloy steels.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness (S) | Radius (RE) |
|---|---|---|---|---|
| Metric | DNMG150608-MA | 12.70 mm | 6.35 mm | 0.80 mm |
| Imperial | DNMG442-MA | 1/2" | 1/4" | 0.0315" (1/32") |
Recommended Cutting Parameters
*VP15TF is universal. The 0.8mm radius allows for aggressive feeds on stable workpieces.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 100 - 200 m/min | 0.12 - 0.40 mm/r | 1.00 - 4.50 mm |
| Alloy Steel (4140/SCM440) | 120 - 250 m/min | 0.15 - 0.45 mm/r | 1.50 - 5.00 mm |

VP15TF (Universal Performance): Best for CNC mass production. It has superior wear resistance at modern cutting speeds and handles a wider range of materials (Steel, Stainless, and Alloys).
US735 (Toughness Special): Choose US735 only for heavy interrupted cuts or extremely low-speed machining in stainless steel. For 95% of job-shop and production CNC work, VP15TF is the superior, more productive grade.

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.
