UC5115 Grade Material
The UC5115 grade is Mitsubishi's premier choice for Cast Iron turning. By utilizing a thick CVD coating with optimized Alumina ($Al_2O_3$) layers, it achieves extreme hardness. This indexable turning insert is designed to withstand the abrasive nature of grey and ductile iron while maintaining a sharp edge.
MA Chipbreaker Geometry
The MA chipbreaker is a balanced medium-cutting geometry. Even in brittle materials like cast iron, it provides a stable cutting action that reduces vibration and improves surface finish. It prevents chip welding and facilitates high-speed machining without compromising tool integrity.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Grey Cast Iron (FC250) | 200 - 450 m/min | 0.15 - 0.45 mm/rev | 0.5 - 4.0 mm |
| Ductile Cast Iron (FCD) | 150 - 350 m/min | 0.15 - 0.40 mm/rev | 0.5 - 3.5 mm |

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.
