CCMT120412 UE6020
Heavy-Duty Turning | CVD Coated Carbide | 1.2mm Radius
Material Science & Edge Geometry
UE6020 Grade (CVD Coated Carbide): The UE6020 is a premier **CVD (Chemical Vapor Deposition)** grade designed for **Steel Machining (ISO P20-P35)**. It features a thick, multi-layer **TiCN + Al2O3 + TiN** coating. The Aluminum Oxide layer provides an industry-leading thermal barrier, allowing the insert to withstand the intense heat generated by high-feed rates on carbon and alloy steels.
1.2mm Radius (The Heavy-Duty Specialist): This is the largest standard radius for the CCMT 12 size. A **1.2mm (3/64") radius** distributes cutting forces over a wider area, drastically increasing edge life and allowing for much higher **feed per revolution (fn)**. It is ideal for workpieces with surface scale or when machining large diameters where tool pressure is less of a concern than edge wear.
Metric vs. Imperial Specifications
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT120412 | 12.70 mm | 4.76 mm | 1.20 mm |
| Imperial | CCMT433 | 0.500" (1/2") | 0.187" (3/16") | 0.0472" (3/64") |
Heavy-Duty Cutting Parameters
*The 1.2mm radius generates higher radial force. Ensure your machine and tool holder (SCLCR 12) have maximum rigidity.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (1045) | 140 - 320 m/min | 0.15 - 0.45 mm/r | 0.60 - 3.00 mm |
| Alloy Steel (4140) | 120 - 260 m/min | 0.12 - 0.35 mm/r | 0.60 - 2.50 mm |

UE6020 (CVD Carbide): This is your Production Beast. While a 0.4mm radius (120404) provides a finer finish at low feeds, the 1.2mm radius (120412) is designed for Bulk Material Removal and heavy semi-finishing where the goal is maximum "Uptime."
Surface Finish Tip: To achieve a good finish with a 1.2mm radius, you must increase your feed rate. If the feed is too low, the insert will rub rather than cut, leading to vibration and premature wear.

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.
