CCMT060204 UE6020
General Steel Specialist | CVD Coated Carbide | 0.4mm Radius
Material & Chipbreaker Analysis
UE6020 Grade (CVD Coated Carbide): Engineered for **General Steel Machining (ISO P20-P35)**. This grade features a thick multi-layer CVD coating (TiCN+Al2O3+TiN) that provides superior wear resistance and thermal protection. It excels in maintaining edge integrity under the high temperatures generated during continuous steel turning.
Positive 80° Rhombic Geometry: The 7-degree positive rake angle is designed for low cutting resistance. The **0.4mm (1/64") radius** is the perfect "all-rounder," durable enough for semi-roughing while remaining sharp enough to produce a high-quality finish on carbon and alloy steels.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT060204 | 6.35 mm | 2.38 mm | 0.40 mm |
| Imperial | CCMT21.51 | 1/4" | 3/32" | 0.0157" |
Recommended Cutting Parameters
*Optimized for ISO P-class Steel. Use coolant for improved chip evacuation and tool life.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel | 140 - 300 m/min | 0.05 - 0.20 mm/r | 0.30 - 1.50 mm |
| Alloy Steel | 120 - 250 m/min | 0.05 - 0.18 mm/r | 0.30 - 1.20 mm |

Shop SCLCR 06 HoldersGrade Comparison: UE6020 vs VP15TF
UE6020 (CVD): Optimized for Steel only. High wear resistance in continuous cutting. This is your primary choice for speed in carbon steel.
VP15TF (PVD): A multi-purpose grade. Use this if you are switching between Steel and Stainless Steel, or if your machine lacks rigidity and causes tool chatter.

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.
