UE6020 CVD Coating Technology
The UE6020 grade is a CVD-coated carbide designed to thrive in high-heat environments. It uses a thick Alumina (Al2O3) layer that acts as a thermal barrier, preventing heat from penetrating the carbide core. This is essential for High-speed turning of carbon steel, where PVD coatings might fail due to thermal softening.
MV Medium-Finish Chipbreaker
The MV chipbreaker is designed for "Multi-Value" performance. It excels in both finishing and semi-finishing. Combined with the 0.8mm radius, it allows for a larger depth of cut (DOC) and higher feed rates without compromising chip control, ensuring your automated CNC runs smoothly without chip nesting.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Low Carbon Steel | 150 - 320 m/min | 0.10 - 0.25 mm/rev | 0.5 - 2.5 mm |
| Alloy Steel (Medium Hard) | 120 - 250 m/min | 0.08 - 0.20 mm/rev | 0.3 - 2.0 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.
