Thick-Body Thermal Stability | Mirage PVD Finishing | MA Low-Friction Geometry
Maximum Stability for Fine Finishing
VP15TF Grade (Mirage PVD Coating): The VP15TF is Mitsubishi's premier PVD solution for difficult-to-cut materials. The "Mirage" coating is a nano-layered structure that remains stable under high heat while providing an ultra-smooth surface. This specifically prevents Built-Up Edge (BUE) on gummy materials like 304/316 Stainless Steel, ensuring the finished part remains within micron-level tolerances.
MA Chipbreaker (Precision Precision): The MA geometry is engineered to reduce radial cutting forces. In finishing operations, this is vital to prevent "pushing" the workpiece, which causes taper. It provides sharp, clean chip breaking even at very low depths of cut.
6.35mm Thickness (The "06" Stability): While most finishing inserts are 4.76mm thick, the DNMG1506 series uses a 6.35mm body. This extra mass absorbs cutting vibrations and dissipates heat much faster, protecting the sharp 0.4mm tip from thermal cracking and premature wear.
Metric vs. Imperial Comparison

Recommended Cutting Parameters
*Optimized for finishing. High-pressure coolant is highly recommended for Stainless Steel.
| Material Group | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 80 - 180 m/min | 0.05 - 0.20 mm/r | 0.20 - 2.00 mm |
| Heat-Resistant Alloys | 30 - 70 m/min | 0.05 - 0.15 mm/r | 0.20 - 1.50 mm |

Shop DDJNR 15 HoldersPro-Tip: VP15TF vs. US735
VP15TF (The Precision Choice): Use this for continuous finish passes where tool life and surface finish are primary. It maintains a sharper edge longer under high heat.
US735 (The Mechanical Choice): Switch to US735 only if your finishing pass involves heavy interruptions or unstable workpiece clamping. For general CNC precision work, VP15TF is the industry standard.

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.
