DCMT11T302 UE6020
Anti-Vibration Steel Specialist | UE6020 CVD Coating | 0.2mm Radius
Precision Engineering for Steel Finishing
UE6020 Grade (CVD Multi-Layer): The UE6020 is a premium CVD-coated carbide grade optimized for stable steel turning. It features a thick TiCN + Al2O3 coating that provides excellent crater wear resistance. It is the ideal choice for medium-to-high speed finishing of carbon and alloy steels where tool life and surface consistency are paramount.
DCMT Geometry (Positive Rake): The 55-degree diamond shape with a positive chipbreaker ensures smooth chip evacuation and reduces the heat generated at the cutting edge. This prevents thermal deformation of the workpiece and ensures high dimensional accuracy.
0.2mm Radius (Low Force Specialist): The ultra-sharp 0.2mm radius is designed to minimize radial cutting pressure. If you are struggling with chatter or vibration on long-reach tools or thin-walled parts, this radius is the industry-standard solution to achieve a flawless finish.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT11T302 | 9.525 mm | 3.97 mm | 0.20 mm |
| Imperial | DCMT32.50.5 | 3/8" | 5/32" | 0.0078" |
Recommended Machining Parameters
*The 0.2mm radius requires delicate feed rates to maintain edge life and avoid chipping.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (1045) | 180 - 350 m/min | 0.03 - 0.10 mm/r | 0.05 - 0.80 mm |
| Alloy Steel (4140) | 150 - 300 m/min | 0.03 - 0.08 mm/r | 0.05 - 0.60 mm |
Compatible Tool Holders
Maximum performance when paired with SDJCR or SDUCR 11-series holders:

UE6020 (Steel Specialist): Best for continuous high-speed runs on carbon steel. Excellent for high-volume productivity.
VP15TF (PVD General Purpose): If you are machining a mix of steel, stainless, and heat-resistant alloys on the same machine, switch to VP15TF. It is the "all-rounder" for mixed-material shops.

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.
