VP15TF Miracle Coating
The VP15TF grade features Mitsubishi’s unique Miracle (Al,Ti)N PVD coating. This nano-layered coating provides superior oxidation resistance and high hardness even at elevated cutting temperatures. It effectively prevents built-up edge (BUE) when machining sticky materials like stainless steel, significantly extending tool life in both dry and wet conditions.
JM Medium Chipbreaker
The JM Chipbreaker geometry is the versatile choice for general-purpose milling. It balances a sharp cutting edge for reduced cutting resistance with a robust land to protect against fracture. This optimized geometry results in consistent chip evacuation and a smooth surface finish on your workpiece, even during varied depths of cut.

General Application Guide (VP15TF Miracle Coated)
| Material Group | Cutting Speed ($v_c$) | Feed per Tooth ($f_z$) | Depth of Cut ($a_p$) |
|---|---|---|---|
| Mild / Carbon Steel | 150 - 250 m/min | 0.10 - 0.25 mm/t | 0.5 - 4.5 mm |
| Stainless Steel (SUS304) | 100 - 180 m/min | 0.08 - 0.20 mm/t | 0.5 - 3.5 mm |

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.
