DCMT11T308 UE6020
High-Strength Steel Specialist | UE6020 CVD Grade | 0.8mm Radius
Optimized for High-Feed Steel Machining
UE6020 Grade (Advanced CVD Coating): The UE6020 is Mitsubishi’s premier choice for general steel turning (P10-P30). It utilizes a thick TiCN + Al2O3 + TiN coating layers that offer a superior thermal barrier. This grade is engineered to resist crater wear and plastic deformation, ensuring long tool life during high-speed continuous machining of carbon and alloy steels.
DCMT Geometry (Positive Chipbreaker): The 55-degree diamond shape with a 7-degree positive relief angle reduces cutting resistance. This "free-cutting" geometry is critical for reducing heat generation and preventing work-hardening, even during deeper cuts.
0.8mm Radius (The Robust Choice): The "08" nose radius is designed for durability. It allows for higher feed rates than the 0.4mm version and provides a stronger edge that can withstand slight scale or surface irregularities in semi-roughing applications.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT11T308 | 9.525 mm | 3.97 mm | 0.80 mm |
| Imperial | DCMT32.52 | 3/8" | 5/32" | 0.0315" (1/32") |
Recommended Machining Parameters
*The 0.8mm radius allows for increased feed rates. Ensure workpiece stability for maximum results.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (1045/S45C) | 180 - 320 m/min | 0.15 - 0.35 mm/r | 0.50 - 2.50 mm |
| Alloy Steel (4140/SCM440) | 150 - 280 m/min | 0.12 - 0.30 mm/r | 0.50 - 2.00 mm |

UE6020 (Steel Specialist): Your first choice for carbon steel production. It offers the highest wear resistance for continuous long-path turning.
US735 (Stainless Specialist): If your job involves Stainless Steel or heavy interrupted cuts (like turning a shaft with a keyway), switch to US735 for its superior fracture toughness.

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.
