TNMG160404-MA UE6110
Mitsubishi Materials | The Benchmark for High-Speed Steel Turning
The Mitsubishi TNMG160404-MA UE6110 is a high-performance CVD coated carbide insert engineered for superior efficiency in steel turning applications. Utilizing the UE6110 grade, which features a thick, heat-resistant $Al_2O_3$ (Alumina) layer, this insert provides exceptional protection against crater wear. Designed as a long-tail precision tool, it incorporates the MA chipbreaker to ensure stable chip evacuation during medium-duty CNC machining of carbon and alloy steels.

UE6110 Grade Material
The UE6110 grade is Mitsubishi's specialized CVD turning insert material for high-speed P-class steel machining. It employs a superior coating adhesion technology that prevents peeling, ensuring the insert maintains a sharp cutting edge even under high thermal loads common in continuous turning.
MA Chipbreaker Geometry
The MA chipbreaker is a versatile medium-cutting geometry. Its primary advantage is providing a low cutting force while preventing chip nesting. This leads to reduced heat generation at the tool tip, further extending the tool life of the indexable turning insert in high-velocity operations.

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.
