Material & Chip Control Technology
VP15TF Miracle Grade (PVD Coating): This grade consists of a micro-grain carbide substrate coated with a specialized Al-Ti-N (Miracle Coating). It provides exceptional oxidation resistance and hardness, effectively preventing built-up edge (BUE) and ensuring stable performance in interrupted cutting.
MV Chipbreaker: The MV geometry is designed for medium-range applications. It provides excellent chip control across a wide range of feed rates, reducing cutting resistance and ensuring a high surface finish on your workpiece.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 80 - 180 m/min | 0.10 - 0.30 mm/rev | 0.5 - 2.5 mm |
| Carbon/Alloy Steel | 100 - 250 m/min | 0.15 - 0.35 mm/rev | 1.0 - 3.0 mm |

VP15TF is your most versatile choice for general machining. However, if you are focusing strictly on mass production of steel under stable conditions, consider UE6020 for higher speed. If your task is purely high-speed finishing of carbon steel, NX2525 cermet may provide a superior mirror 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.
