Material & Chipbreaker Details
Grade UE6020 (CVD Coated Carbide): This grade features a thick TiCN + Al2O3 coating. It is the first choice for P10-P30 steel applications. It offers extreme heat resistance and toughness, making it a reliable long-life turning insert for carbon and alloy steels.
MV Chipbreaker: Designed for medium-range cutting, providing excellent chip control at various depths of cut, reducing the risk of "bird-nesting" during CNC operations.
Recommended Cutting Parameters
To maximize tool life and surface finish, use the following starting values:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Carbon Steel / Alloy Steel | 150 - 300 m/min | 0.15 - 0.40 mm/rev |

If you are experiencing chipping in heavy interrupted cuts, consider upgrading to UE6110 for higher toughness. For high-speed finishing in stable conditions, MC6025 is an excellent alternative. The VCMT160408 UE6020 remains the best "all-rounder" for general steel processing.

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.
