TNMG160404-MA UE6020
Mitsubishi Materials | The Ultimate All-Rounder for Steel Turning
The Mitsubishi TNMG160404-MA UE6020 is a high-versatility CVD coated carbide insert engineered for stable to light-interrupted turning of carbon and alloy steels. Utilizing the UE6020 grade, which provides an ideal balance of hardness and fracture toughness, this insert is the go-to long-tail precision tool for general-purpose CNC machining. The MA chipbreaker ensures reliable chip evacuation across a broad range of medium-cutting applications.

UE6020 Material Grade
The UE6020 grade is Mitsubishi's benchmark for stable steel turning. It features a robust CVD coating that provides excellent heat insulation and resistance to edge chipping. This indexable turning insert is specifically tuned for P25-P35 steel groups, offering reliable performance even in less-than-perfect setups.
MA Chipbreaker Logic
The MA chipbreaker is a medium-cutting geometry that balances edge sharpness with structural strength. It prevents chip welding and nesting, making it suitable for both carbon steels and mild steels. Its design is ideal for mid-range depths of cut and feed rates.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
