Mitsubishi Materials | The Heavy-Duty Mirror Finish Cermet
The Mitsubishi TNMG160416 NX2525 is a high-performance cermet turning insert engineered for precision finishing with an emphasis on edge strength. Utilizing the NX2525 titanium-cermet grade, this insert provides exceptional chemical stability and resistance to built-up edge (BUE). With its large 1.6mm nose radius, it is the ultimate long-tail precision tool for high-feed stable turning of carbon and alloy steels, ensuring a mirror-like surface finish even in demanding conditions.

NX2525 Titanium Cermet
The NX2525 grade is Mitsubishi’s premier micro-grain cermet. Unlike standard carbide, cermet has a low affinity for metal, which virtually eliminates the welding of work material to the edge. This makes it the top choice for precision machining where surface brightness and dimensional accuracy are critical.
1.6mm Radius Advantage
The larger 1.6mm nose radius on this indexable turning insert provides superior edge strength and allows for higher feed rates without sacrificing surface finish quality. It is ideal for larger workpieces or when high productivity in a finishing pass is required.

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.
