UE6020 Material Grade
The UE6020 grade is Mitsubishi's benchmark for stable steel turning. It features a robust CVD coating that provides excellent heat insulation and resistance to edge chipping. This indexable turning insert is specifically tuned for P25-P35 steel groups, offering reliable performance even in less-than-perfect setups.
MA Chipbreaker Logic
The MA chipbreaker is a medium-cutting geometry that balances edge sharpness with structural strength. It prevents chip welding and nesting, making it suitable for both carbon steels and mild steels. Its design is ideal for mid-range depths of cut and feed rates.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Low Carbon Steel | 150 - 300 m/min | 0.10 - 0.35 mm/rev | 0.5 - 3.5 mm |
| Alloy Steel | 120 - 250 m/min | 0.10 - 0.30 mm/rev | 0.5 - 3.0 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.
