- Imperial (ANSI): VCMT 331
Advanced Material Technology
UC5115 Grade (CVD Coating): This grade features a thick Al2O3 (Alumina) coating layer optimized for grey and ductile cast iron. It provides exceptional crater wear resistance and flank wear resistance at high speeds. The "Super" Toughness substrate ensures the tool remains stable during continuous cutting.
Standard Chipbreaker: Specifically designed for medium-to-finish turning, ensuring smooth chip evacuation even in short-chip materials like cast iron, preventing built-up edge and scratching.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Grey Cast Iron (FC) | 150 - 450 m/min | 0.10 - 0.25 mm/rev | 0.5 - 2.5 mm |
| Ductile Cast Iron (FCD) | 120 - 300 m/min | 0.10 - 0.20 mm/rev | 0.5 - 2.0 mm |
System Integration
Ensure maximum stability by pairing with our high-quality tool holders.

UC5115 is your primary choice for high-speed machining of cast iron. If you are machining steel instead, consider switching to UE6020. For stainless steel applications where toughness is required, US735 or VP15TF remain the superior options.
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.
