DCMT11T302-MV UE6020
High-Speed Finishing Specialist | UE6020 CVD Coating | Anti-Vibration 0.2mm Radius
Optimized for High-Speed Accuracy
UE6020 Grade (High-Speed Steel Expert): The UE6020 is a specialized CVD-coated carbide grade designed for P-Class (Steel) production. It features superior resistance to plastic deformation and crater wear, allowing you to push surface speeds ($Vc$) to the limit in carbon and alloy steel. It is the go-to grade for reducing cycle times in stable, automated CNC environments.
MV Chipbreaker (Precision Control): The MV (Medium-V) geometry is a versatile chipbreaker that excels even at shallow depths. In this 11T3 size, it provides a stable "curl-and-snap" chip action, preventing the long "bird-nest" chips that often occur during light finishing passes on steel.
0.2mm Radius (Anti-Vibration): The sharp "02" nose radius is specifically chosen for applications where radial cutting pressure must be minimized. It is ideal for thin-walled parts, small diameters, or long-reach boring where vibration (chatter) normally limits productivity.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT11T302-MV | 9.525 mm | 3.97 mm | 0.20 mm |
| Imperial | DCMT32.50.5-MV | 3/8" | 5/32" | 0.0078" (1/128") |
Recommended Machining Parameters
*UE6020 is designed for high surface speeds. For thin parts, maintain the lower feed range to ensure surface integrity.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Mild Steel (1020) | 200 - 400 m/min | 0.04 - 0.12 mm/r | 0.15 - 1.00 mm |
| Alloy Steel (4140) | 180 - 350 m/min | 0.04 - 0.10 mm/r | 0.15 - 0.80 mm |

UE6020 (CVD Carbide): Use this for high-productivity steel finishing where speed is the priority. It handles heat better than cermet in high $Vc$ applications.
NX2525 (Cermet): Switch to NX2525 only when a "Mirror Surface" is required. Cermet provides a better aesthetic look, but UE6020 offers higher endurance and stability during long production runs in steel.

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.
