CPMH090304-MV VP15TF
Universal Machining Master | Miracle PVD Coating | MV Sharp Precision
Optimized for Multi-Material Versatility
VP15TF Grade (Miracle PVD Technology): The VP15TF is Mitsubishi’s most versatile PVD-coated carbide. The Miracle Coating (Al-Ti-N) provides extreme hardness and heat resistance. Unlike thick CVD coatings that can round off a sharp edge, this PVD layer is thin and ultra-smooth, preserving the edge sharpness required to slice through gummy stainless steels and preventing "Built-Up Edge" (BUE) in carbon steel.
MV Chipbreaker (The Precision Control): The MV geometry is a medium-cut chipbreaker with an 11-degree positive rake. It is specifically designed to balance edge strength with sharpness. In general steel, it produces manageable "6" shaped chips, while in tougher materials, it reduces cutting resistance to prevent chatter in internal boring operations.
0.4mm (1/64") Finish Radius: The 04 radius is the ideal choice for achieving high-quality surface finishes. It generates minimal radial force, making it the perfect partner for long boring bars or small-diameter workpieces where deflection must be avoided.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CPMH090304-MV | 9.525 mm | 3.18 mm | 0.40 mm |
| Imperial | CPMH321-MV | 3/8" | 1/8" | 0.0157" (1/64") |
Universal Cutting Parameters
*VP15TF is stable across varied materials. Always maintain a consistent feed to prevent surface glazing in stainless.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon/Alloy Steel | 110 - 240 m/min | 0.05 - 0.20 mm/r | 0.25 - 2.00 mm |
| Stainless Steel (304/316) | 80 - 170 m/min | 0.05 - 0.15 mm/r | 0.20 - 1.50 mm |
Pro-Tip: VP15TF vs. NX2525
VP15TF (The High-Toughness Universal): Use this as your standard insert for nearly any material. It is much more forgiving than Cermet in interrupted cuts.
NX2525 (The Mirror Finisher): Switch to NX2525 Cermet only if you are working on stable, high-speed steel finishing and require a reflective surface finish.

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.
