Superalloy Specialist | Miracle PVD VP10RT | MS Sharp Geometry
High-Performance Aerospace Solution
VP10RT Grade (Thermal Shield): The VP10RT is an advanced Miracle PVD grade engineered for S-Class (Superalloys) and M-Class (Stainless Steel). It utilizes a high-aluminum content PVD coating that forms a protective oxide layer at extreme temperatures. This prevents crater wear when machining materials with poor thermal conductivity, such as Titanium and Inconel.
MS Chipbreaker (The Precision Slicer): The MS geometry features a large rake angle that provides an exceptionally sharp cutting edge. This is crucial for "shearing" gummy alloys rather than "pushing" them, which drastically reduces the risk of work hardening and built-up edge (BUE).
0.8mm (1/32") Balanced Radius: The 0.8mm radius is the universal standard for versatility, offering excellent tip strength for semi-roughing while maintaining the sharpness required for a high-quality industrial finish.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CNMG120408-MS | 12.7 mm | 4.76 mm | 0.80 mm |
| Imperial | CNMG432-MS | 1/2" | 3/16" | 0.0315" (1/32") |
Recommended Cutting Parameters
*VP10RT excels in high-heat conditions. Always use high-pressure coolant to maximize tool life in titanium alloys.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Titanium Alloys (Ti-6Al-4V) | 40 - 85 m/min | 0.10 - 0.25 mm/r | 0.50 - 3.00 mm |
| Duplex Stainless Steel | 60 - 120 m/min | 0.12 - 0.30 mm/r | 0.80 - 3.50 mm |
Compatible Tool Holders
Maximum rigidity is essential for tough alloys. Use DCLNR/L 12 series holders:

VP10RT (The Thermal Specialist): Use this when your primary failure is thermal cracking or crater wear. It is specifically optimized for titanium and heat-resistant alloys.
VP15TF (The Versatile Toughness): Choose VP15TF for general stainless steel turning where interrupted cuts and impact toughness are the bigger concerns.

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.
