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 |

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.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
