Mitsubishi VNMG160408 UC5115
Professional CVD Carbide Grade for High-Stability Cast Iron Turning
The Mitsubishi VNMG160408 UC5115 is a high-performance 35° rhombic negative-type carbide turning insert. Engineered specifically for high-speed machining of cast iron, the UC5115 grade provides exceptional abrasive wear resistance and thermal stability. Known globally as the VNMG 332 ANSI equivalent, it is the premier choice for machining gray cast iron (FC) and ductile cast iron (FCD) in high-production CNC environments.

UC5115 Grade & Coating Technology
UC5115 Grade: This is a specialized CVD coated carbide grade designed for the ISO K-group. It features a high-hardness substrate and a thick Al2O3 coating layer that acts as a heat shield, preventing plastic deformation and abrasive wear common in high-speed cast iron turning.
Geometric Edge Strength: The VNMG negative geometry combined with the UC5115 grade offers superior edge toughness. This prevents chipping during interrupted cuts on cast surfaces, ensuring a consistent high surface finish across large batches.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Gray Cast Iron (K10-K20) | 200 - 500 m/min | 0.15 - 0.50 mm/rev | 1.0 - 4.5 mm |
| Ductile Cast Iron (K10-K20) | 150 - 350 m/min | 0.15 - 0.45 mm/rev | 1.0 - 4.0 mm |
System Optimization
For maximum high-speed stability, pair this VNMG 332 insert with our premium high-rigidity tool holders.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
