- ISO (Metric): VCMT160408
- ANSI (Imperial): VCMT 332
Grade & Chipbreaker Technology
UC5115 Grade (CVD Coated): Specifically optimized for cast iron. This grade features a thick Alumina (Al2O3) coating that provides extreme crater wear resistance and thermal stability. It allows for higher cutting speeds compared to conventional grades, significantly reducing cycle times.
Standard Chipbreaker: Optimized for medium-range cutting, ensuring smooth chip evacuation and preventing built-up edge, even in dusty cast iron machining environments.
Cutting Parameters (Recommended)
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Grey Cast Iron | 150 - 450 m/min | 0.15 - 0.40 mm/rev | 0.5 - 3.0 mm |
| Ductile Cast Iron | 120 - 300 m/min | 0.15 - 0.35 mm/rev | 0.5 - 2.5 mm |

UC5115 is your first choice for high-speed cast iron turning. However, if your work involves stainless steel, consider US735 for better toughness. For alloy steel, UE6110 or VP15TF are recommended for superior wear resistance.
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.
