CCMT060208 UE6020
High-Feed Steel Turning | CVD Coated Carbide | 0.8mm Radius
Material & Geometry Analysis
UE6020 Grade (CVD Coated Carbide): This grade features a thick, multi-layer TiCN + Al2O3 + TiN coating. The Aluminum Oxide (Al2O3) layer provides an exceptional thermal barrier, allowing the insert to maintain hardness even at high cutting speeds. Optimized for General Steel Machining (ISO P20-P35), it offers high resistance to crater wear and plastic deformation.
0.8mm Radius (Edge Strength): The larger 0.8mm (1/32") corner radius is designed for stability. It allows for significantly higher feed rates (mm/rev) and a deeper depth of cut than smaller radii, making it the ideal choice for **Semi-Finishing to Light Roughing** on carbon and alloy steels.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT060208 | 6.35 mm | 2.38 mm | 0.80 mm |
| Imperial | CCMT21.52 | 1/4" | 3/32" | 0.0315" |
Recommended Cutting Parameters
*The 0.8mm radius allows for standard finishing to light roughing passes. Use of coolant is highly recommended for CVD grades.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Low Carbon Steel | 150 - 320 m/min | 0.10 - 0.30 mm/r | 0.40 - 2.00 mm |
| Alloy Steel (4140/SCM440) | 120 - 260 m/min | 0.08 - 0.25 mm/r | 0.40 - 1.50 mm |
Required Tool Holder
Maximum stability for SCLCR/L 06 Boring Bars and External Holders:
Shop SCLCR 06 HoldersGrade Comparison Tip
UE6020 (CVD Carbide): Your primary choice for Steel only. High wear resistance in continuous cutting. Best for maximizing tool life in high-speed production.
VP15TF (PVD Carbide): The versatile alternative. Choose VP15TF if you are machining Stainless Steel or if you have heavy vibration and interrupted cuts.
NX2525 (Cermet): Use only for final finishing passes where a mirror-like gloss is required. Cermet is more brittle and cannot handle the high feeds of 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.
