CCMT09T304 UE6020
Steel Turning Specialist | CVD Coated Carbide | 0.4mm Radius
Material & Geometry Analysis
UE6020 Grade (CVD Coated Carbide): Engineered specifically for General Steel Machining (ISO P20-P35). This grade features a robust multi-layer CVD coating (TiCN + Al2O3 + TiN). The thick Aluminum Oxide (Al2O3) layer acts as a thermal shield, preventing heat from penetrating the carbide substrate, which drastically reduces crater wear and edge deformation during high-speed continuous cuts.
80° Positive Rhombic Geometry: The CCMT shape features a 7° positive relief angle, significantly reducing cutting resistance and heat generation. The 0.4mm (1/64") radius provides the perfect balance: it is strong enough to resist chipping during semi-roughing while maintaining the precision required for high-quality finishing passes.

UE6020 (CVD Carbide): This is your Steel Performance grade. It offers much higher wear resistance in continuous steel turning than PVD grades.
VP15TF (PVD Carbide): Use this if you are machining Stainless Steel or have Heavy Interruptions. It is tougher and more resistant to edge chipping but will wear faster in high-speed steel turning compared to UE6020.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
