CNMG120412-MA UE6110
High-Efficiency Rougher | UE6110 CVD Grade | 1.2mm Reinforced Corner
Engineered for Maximum Speed & Feed
UE6110 Grade (High-Temperature CVD): The UE6110 is Mitsubishi’s premium hard-coated grade for P-Class (Steel). It is specifically designed to perform at higher cutting speeds than general-purpose grades. The thickened Al2O3 layer provides an elite thermal barrier, protecting the carbide substrate from the extreme heat generated during high-speed roughing of carbon and alloy steels.
MA Chipbreaker (Medium-Heavy Range): The MA geometry is a robust general-purpose design. On this 12-radius platform, it excels at controlling thick, heavy chips. Its reinforced land area prevents the edge from "cratering" under the high pressure of aggressive metal removal, while the rake angle is optimized to keep cutting forces manageable.
1.2mm (3/64") Radius Edge: The large corner radius is built for Impact and Heat Dissipation. It allows for a higher feed rate per revolution and provides significantly more edge strength than a standard 0.8mm radius, making it perfect for roughing through scale or uneven surfaces at high speed.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CNMG120412-MA | 12.7 mm | 4.76 mm | 1.20 mm |
| Imperial | CNMG433-MA | 1/2" | 3/16" | 0.0472" (3/64") |
High-Speed Roughing Parameters
*The UE6110 grade loves speed. Maintain high Surface Meters per Minute (Vc) for best chip control.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Low Carbon Steel (1020 / S235) | 250 - 480 m/min | 0.25 - 0.55 mm/r | 1.20 - 5.00 mm |
| Alloy Steel (4140 / 4340) | 180 - 350 m/min | 0.20 - 0.45 mm/r | 1.20 - 4.50 mm |

UE6110 (The Efficiency King): Choose this when your setup is stable and you want to increase cycle time. It offers superior wear resistance in high-heat continuous turning.
UE6020 (The Tough Tank): If you are experiencing edge chipping due to heavy vibrations or interrupted cuts (holes/slots), switch to UE6020 for its higher impact 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.
