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 |

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 |

Shop SDJCR 11 HoldersPro-Tip: UE6020 vs. NX2525
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.
