UE6020 Grade & MA Chipbreaker Detail
UE6020 CVD Coated Grade: Designed for the high-speed turning of steel. The UE6020 grade features a triple-layer coating (TiCN-Al2O3-TiN) that provides exceptional resistance to plastic deformation and flank wear. It is the first choice for continuous to lightly interrupted cutting of carbon and alloy steels.
MA Chipbreaker: The MA geometry is a universal "Medium-Range" breaker. It is specifically designed to provide stable chip control over a wide range of feed rates, effectively preventing chip entanglement and protecting the high surface finish of the workpiece.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| 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 |

UE6020 is the gold standard for high-speed steel turning. If your application involves heavy interrupted cutting or high-impact loads, consider switching to UE6110 or MC6025. For stainless steel machining, we recommend the VP15TF Miracle Coating grade for its superior anti-welding properties.

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.
