CNMG120416-MA UE6020
Extreme Roughing Titan | UE6020 CVD Grade | 1.6mm Reinforced Radius
Engineered for Maximum Feed & Impact
UE6020 Grade (CVD Coating Mastery): The UE6020 is a specialized CVD-coated grade optimized for P-Class (Steel). It features a multi-layer structure of TiCN and Alumina (Al2O3) that provides a superior thermal barrier. This prevents the cutting edge from softening during the high-heat generation associated with deep depths of cut in carbon and alloy steels.
MA Chipbreaker (Heavy-Medium Versatility): The MA geometry is Mitsubishi's legendary general-purpose chipbreaker. On this 1.6mm radius platform, it is optimized to direct chips away from the workpiece at high volumes, preventing chip re-cutting and surface damage even when the feed rate is significantly increased.
1.6mm (1/16") Reinforced Radius: This is the strongest corner radius available for the 1204 series. It is purpose-built to survive heavy interruptions and high-vibration environments. The large radius also helps in dissipating heat across a wider area, drastically increasing tool life during continuous heavy roughing.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CNMG120416-MA | 12.7 mm | 4.76 mm | 1.60 mm |
| Imperial | CNMG434-MA | 1/2" | 3/16" | 0.063" (1/16") |
Recommended Roughing Parameters
*Note: The 1.6mm radius creates higher radial pressure. Ensure your tool holder and machine have high rigidity.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Low Carbon Steel (A36/1020) | 150 - 350 m/min | 0.30 - 0.75 mm/r | 1.60 - 6.00 mm |
| Alloy Steel (4140/4340) | 120 - 280 m/min | 0.25 - 0.60 mm/r | 1.60 - 5.00 mm |

CNMG120416 (The Beast): Choose this when your priority is Edge Security and High Productivity. If you are breaking 1.2mm radius inserts or need a stronger edge for raw casting skins, this is your solution.
Surface Finish Note: Due to the large radius, this insert will produce a "wiper-like" effect on finishing passes, but requires higher feed rates to prevent "rubbing" and vibration.

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.
