Metric vs. Inch (ANSI) Reference
This precision turning tool is available under the following international standards:
- ISO (Metric): VCMT160408
- ANSI (Imperial): VCMT 332
Grade & Chipbreaker Technology
UC5115 Grade (CVD Coated): Specifically optimized for cast iron. This grade features a thick Alumina (Al2O3) coating that provides extreme crater wear resistance and thermal stability. It allows for higher cutting speeds compared to conventional grades, significantly reducing cycle times.
Standard Chipbreaker: Optimized for medium-range cutting, ensuring smooth chip evacuation and preventing built-up edge, even in dusty cast iron machining environments.
Cutting Parameters (Recommended)
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Grey Cast Iron | 150 - 450 m/min | 0.15 - 0.40 mm/rev | 0.5 - 3.0 mm |
| Ductile Cast Iron | 120 - 300 m/min | 0.15 - 0.35 mm/rev | 0.5 - 2.5 mm |
System Compatibility

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.
