UC5115 Grade & Geometry Analysis
UC5115 CVD Grade: This grade is a specialized CVD coated carbide specifically optimized for ISO K group (Cast Iron). It features an extremely hard substrate combined with a thick Al2O3 coating layer, providing superior resistance to abrasive wear and chipping even at high cutting temperatures.
Stable Geometry: The 35° rhombic profile allows for excellent profiling accessibility. Combined with a robust cutting edge, it prevents edge plastic deformation and ensures a consistent high surface finish throughout the production run.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Gray Cast Iron (FC) | 150 - 450 m/min | 0.10 - 0.35 mm/rev | 0.5 - 3.0 mm |
| Ductile Cast Iron (FCD) | 120 - 350 m/min | 0.10 - 0.30 mm/rev | 0.5 - 2.5 mm |
Optimize Your Setup
Ensure maximum stability for cast iron machining by pairing this VNMG 331 insert with our high-rigidity holders.

UC5115 is your first choice for stable cast iron turning. For applications involving heavy interrupted cutting or high-impact ductile iron, consider the tougher UC5105 or MC5005 series. If you are machining steel, switch to the UE6110 or MC6025 grades for optimal performance.
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.
