UE6020 Grade & Geometry Analysis
UE6020 Grade: This is a dedicated CVD coated carbide grade specifically optimized for general-purpose steel turning. It features a tough substrate combined with a multi-layer coating that combats crater wear and flank wear, even during fluctuating cutting conditions. It is ideal for ISO P20-P35 applications.
Cutting Geometry: The negative 35-degree angle provides high edge strength for precision profiling. It is designed to minimize work hardening on the workpiece surface while maintaining stable chip flow during medium-range cutting.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Low Carbon Steel | 150 - 300 m/min | 0.10 - 0.35 mm/rev | 0.5 - 3.0 mm |
| Alloy Steel (SCM) | 120 - 250 m/min | 0.10 - 0.30 mm/rev | 0.5 - 2.5 mm |

UE6020 is your "Universal Choice" for stable steel machining. If you are performing high-speed continuous cutting on carbon steel, we recommend upgrading to UE6110. For heavy interrupted cuts where impact is high, the tougher UE6035 grade will prevent premature edge chipping.

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.
