Global Interchangeability: ISO vs. ANSI
This insert is utilized globally under two primary naming conventions:
- Metric (ISO): VCMT160404
- 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
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.
