High-Feed Steel Turning | CVD Coated Carbide | 0.8mm Radius
Material Science & Geometry
UE6020 Grade (CVD Coated Carbide): This grade is the industry standard for Steel Turning (ISO P20-P35). It features a triple-layer coating (TiCN+Al2O3+TiN) that provides extreme heat resistance. The Aluminum Oxide (Al2O3) layer acts as a thermal barrier, allowing for high cutting speeds without the edge softening seen in PVD grades.
0.8mm Radius (Productivity Edge): The larger corner radius provides a more robust cutting edge, reducing the risk of chipping under high loads. This geometry allows you to increase the feed rate (mm/rev), effectively reducing cycle times while maintaining excellent surface integrity on structural and alloy steels.
Metric vs. Imperial Specifications
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT09T308 | 9.525 mm | 3.97 mm | 0.80 mm |
| Imperial | CCMT32.52 | 0.375" (3/8") | 0.156" (5/32") | 0.0315" (1/32") |
Recommended Cutting Parameters
*The 0.8mm radius allows for deeper and faster cuts. Best results are achieved with flood coolant for chip evacuation.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (1045) | 150 - 350 m/min | 0.12 - 0.35 mm/r | 0.40 - 2.00 mm |
| Alloy Steel (4140) | 120 - 280 m/min | 0.10 - 0.30 mm/r | 0.40 - 1.50 mm |

Shop SCLCR 09 HoldersGrade Selection Tips
UE6020 (CVD Carbide): Optimized for General Purpose Steel Turning. It is much more durable than cermet for roughing and semi-finishing.
VP15TF (PVD Carbide): Choose this for Stainless Steel or very small, precise work where tool vibration is a concern.
NX2525 (Cermet): Use only for Mirror Finishing. Cermet will chip under the high feed rates that UE6020 handles with ease.

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.
