Universal Strength Ace | Miracle PVD Coating | MV Versatile Geometry
Maximum Reliability Across All Materials
VP15TF Grade (Miracle PVD Technology): The VP15TF is Mitsubishi’s most famous universal grade. The **Miracle PVD coating** (Aluminum Titanium Nitride) provides an exceptional balance of wear resistance and toughness. Unlike CVD coatings, this PVD layer is thin and sharp, which prevents the "tearing" of gummy materials like 304 stainless steel while providing enough hardness to machine hardened alloy steels.
MV Chipbreaker (The Multi-Material Solution): The MV geometry is a medium-cut chipbreaker with an 11-degree positive rake. It is specifically designed to handle "voluminous" chips. In carbon steel, it breaks chips into tight C-shapes; in stainless steel, it slices through the material to minimize work hardening and heat generation.
0.8mm (1/32") Robust Edge: The 08 radius is the "productivity" radius. It provides a thicker cross-section at the tool tip, allowing for faster feed rates and providing higher resistance to chipping during interrupted cuts or rough surface skins.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CPMH080208-MV | 7.94 mm | 2.38 mm | 0.80 mm |
| Imperial | CPMH2.522-MV | 5/16" | 3/32" | 0.0315" (1/32") |
Universal Cutting Parameters
*The 0.8mm radius allows for higher feed rates. VP15TF is stable across a wide speed range.
| Material Group | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon/Alloy Steel | 90 - 200 m/min | 0.10 - 0.28 mm/r | 0.50 - 2.00 mm |
| Stainless (304/316) | 70 - 150 m/min | 0.08 - 0.22 mm/r | 0.40 - 1.50 mm |

Shop Turning HoldersPro-Tip: VP15TF vs. UE6020
VP15TF (The Multi-Tasker): Use this as your standard "go-to" insert for mixed material jobs. It is much more resistant to chipping than CVD grades in unstable setups.
UE6020 (The High-Speed Steel Specialist): Switch to UE6020 only for high-volume carbon steel production where machine stability is high and speed is the priority.

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.
