Mitsubishi VNMG160412 UC5115
High-Stability CVD Carbide Grade for Heavy Cast Iron Turning
The Mitsubishi VNMG160412 UC5115 is a robust 35° rhombic negative-type carbide turning insert. Engineered specifically for the high-speed machining of cast iron, the UC5115 grade provides industry-leading abrasive wear resistance. This VNMG 333 ANSI equivalent features a larger 1.2mm nose radius, making it the premier choice for heavy finishing to medium roughing of gray cast iron (FC) and ductile cast iron (FCD).

Global Standards: Metric vs. Inch
This long-life cast iron turning tool is standardized for global CNC machining compatibility:
- ISO (Metric): VNMG160412
- ANSI (Imperial): VNMG 333
UC5115 Grade & Coating Technology
UC5115 CVD Grade: This grade is a specialized CVD coated carbide designed for the ISO K-group (Cast Iron). It features an exceptionally hard substrate and a thick Al2O3 coating layer which acts as a thermal barrier, preventing edge plastic deformation and abrasive wear during high-velocity cast iron machining.
Rugged Geometry: The 1.2mm nose radius provides excellent edge toughness, making the VNMG160412 highly resistant to chipping even when encountering sand inclusions or scaly surfaces on castings.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Gray Cast Iron (K10-K20) | 200 - 450 m/min | 0.20 - 0.55 mm/rev | 1.5 - 4.5 mm |
| Ductile Cast Iron (K10-K20) | 150 - 350 m/min | 0.20 - 0.50 mm/rev | 1.2 - 4.0 mm |
System Optimization
Ensure maximum stability for heavy cutting by pairing this VNMG 333 insert with our high-rigidity tool holders.
