Mitsubishi Materials | The Mirror-Finish Cermet Authority
The Mitsubishi TNMG160408 NX2525 is a high-performance cermet turning insert engineered for precision finishing operations. Utilizing the advanced NX2525 titanium-based cermet grade, this tool excels in high-speed finishing of carbon and alloy steels. It provides superior chemical stability and resistance to oxidation, making it the premier long-tail precision tool for achieving a mirror-like surface finish that traditional carbide grades cannot match.

NX2525 Cermet Grade
The NX2525 grade is a composite material of ceramic and metal (Cermet). It provides superior resistance to built-up edge (BUE) compared to standard carbide. Because cermet has a low affinity for steel, this indexable turning insert maintains a sharp cutting edge for longer, ensuring mirror-finish results and tight dimensional tolerances.
TNMG General Geometry
The TNMG 6-edged design offers exceptional cost-performance for CNC finishing. The 0.8mm radius provides increased edge strength over the 0.4mm version, allowing for slightly higher feed rates while maintaining a high surface finish quality. This is the "workhorse" geometry for stable finishing passes.

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.
