The All-In-One Shop Solution
VP15TF Grade (Miracle PVD Coating): The VP15TF is one of the most versatile grades ever produced. Using Mitsubishi’s proprietary Miracle Coating (Al-Ti-N) technology, it provides an ultra-smooth surface that resists welding and built-up edge. Because it is a PVD grade, the cutting edge remains much sharper than CVD alternatives, making it the premier choice for precision finishing and small lathes where high speeds aren't always possible.
MV Chipbreaker (The Versatile Finisher): The MV geometry is designed for the 11-degree positive CPMH series. It features a specialized rake face that creates excellent chip breaking even at low depths of cut. Whether you are cutting gummy low-carbon steel or tough stainless, the MV breaker ensures chips are managed safely away from the workpiece.
0.4mm (1/64") Radius: The 04 radius is the standard for high-precision finishing. It offers the lowest radial cutting pressure, preventing chatter and ensuring tight dimensional tolerances on slender parts.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CPMH080204-MV | 7.94 mm | 2.38 mm | 0.40 mm |

Universal Cutting Parameters
*VP15TF is highly versatile. For best results in Stainless Steel, use slightly lower speeds with consistent feed rates.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon/Alloy Steel | 100 - 220 m/min | 0.05 - 0.20 mm/r | 0.20 - 1.50 mm |
| Stainless Steel (304/316) | 80 - 160 m/min | 0.05 - 0.15 mm/r | 0.20 - 1.20 mm |
Compatible Tool Holders
Works perfectly with SCLC series external holders or precision boring bars:
Shop SCLC HoldersPro-Tip: VP15TF vs. UE6020
VP15TF (The Multi-Tasker): Use this when you are running multiple materials (Steel, Stainless, Iron) in the same machine and want a single, reliable insert.
UE6020 (The Steel Specialist): Switch to UE6020 only if you are doing long production runs of Carbon Steel and want higher wear resistance via CVD coating.

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.
