DCMT11T308-MV UE6020
High-Strength Steel Specialist | UE6020 CVD Coating | MV Versatile Geometry
Engineered for High-Feed Reliability
UE6020 Grade (The Steel Master): The UE6020 is a specialized CVD-coated carbide specifically for P-Class (Steel). It is designed to withstand the high-temperature friction of high-speed continuous cutting. The multi-layered coating prevents crater wear and plastic deformation, ensuring that the cutting edge remains stable during long production runs in carbon and alloy steels.
MV Chipbreaker (Medium-V): The MV chipbreaker is the workhorse of the Mitsubishi lineup. It is designed to provide stable chip control across a wide range of cutting depths. Even at high feed rates, the MV geometry ensures chips are broken quickly, protecting the finished surface and the machine operator.
0.8mm Radius (High Strength): The "08" (1/32") radius is engineered for edge security. It is significantly more durable than the 0.4mm version, allowing for higher feed rates ($fn$) and deeper passes ($Ap$). This makes it the ideal choice for semi-roughing or when the material has a rough skin.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT11T308-MV | 9.525 mm | 3.97 mm | 0.80 mm |
| Imperial | DCMT32.52-MV | 3/8" | 5/32" | 0.0315" (1/32") |
Recommended Machining Parameters
*UE6020 excels at high surface speeds. Maintain consistent coolant flow for heat management.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| General Steel (1045/1018) | 150 - 350 m/min | 0.10 - 0.30 mm/r | 0.50 - 2.50 mm |
| Alloy Steel (4140/4340) | 120 - 300 m/min | 0.08 - 0.25 mm/r | 0.40 - 2.00 mm |

UE6020 (CVD Carbide): Optimized for steel. Use this for carbon and alloy steel to achieve the longest possible tool life at high speeds.
US735 (CVD Carbide): Switch to US735 ONLY for stainless steel or if your steel cut is heavily interrupted. UE6020 is superior in pure, continuous steel turning.

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.
