CCMT09T304 UE6020
Steel Turning Specialist | CVD Coated Carbide | 0.4mm Radius
Material & Geometry Analysis
UE6020 Grade (CVD Coated Carbide): Engineered specifically for General Steel Machining (ISO P20-P35). This grade features a robust multi-layer CVD coating (TiCN + Al2O3 + TiN). The thick Aluminum Oxide (Al2O3) layer acts as a thermal shield, preventing heat from penetrating the carbide substrate, which drastically reduces crater wear and edge deformation during high-speed continuous cuts.
80° Positive Rhombic Geometry: The CCMT shape features a 7° positive relief angle, significantly reducing cutting resistance and heat generation. The 0.4mm (1/64") radius provides the perfect balance: it is strong enough to resist chipping during semi-roughing while maintaining the precision required for high-quality finishing passes.
Metric vs. Imperial Specifications
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT09T304 | 9.525 mm | 3.97 mm | 0.40 mm |
| Imperial | CCMT32.51 | 0.375" (3/8") | 0.156" (5/32") | 0.0157" (1/64") |
Recommended Cutting Parameters
*Optimized for Carbon and Alloy Steels. For maximum tool life in UE6020, use with constant flood coolant.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (1045) | 150 - 320 m/min | 0.05 - 0.25 mm/r | 0.20 - 1.50 mm |
| Alloy Steel (4140) | 120 - 260 m/min | 0.05 - 0.20 mm/r | 0.20 - 1.20 mm |

UE6020 (CVD Carbide): This is your Steel Performance grade. It offers much higher wear resistance in continuous steel turning than PVD grades.
VP15TF (PVD Carbide): Use this if you are machining Stainless Steel or have Heavy Interruptions. It is tougher and more resistant to edge chipping but will wear faster in high-speed steel turning compared to UE6020.

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.
