Mitsubishi Materials | The High-Speed Cermet Specialist
The Mitsubishi TNGG160408R-F NX2525 is a high-performance cermet turning insert designed for high-speed finishing operations. Utilizing the advanced NX2525 titanium-cermet grade, this insert provides superior chemical stability and resistance to oxidation compared to standard carbide. Combined with the F chipbreaker, it is the ultimate choice for precision turning of carbon and alloy steels where a mirror-like surface finish is mandatory.

NX2525 Cermet Grade
The NX2525 grade is a specialized cermet (ceramic-metal composite) that offers extremely low chemical affinity for steel. This prevents "smearing" at high cutting speeds, ensuring that this indexable turning insert delivers unmatched surface brightness and sharp-edge retention during high-speed finishing.
F Chipbreaker (Fine Machining)
The F chipbreaker is specifically designed for ultra-light depths of cut. Its geometry optimizes chip evacuation even in softer steels, preventing long tangled chips from damaging the mirror-like finish of the workpiece. This right-hand (R) model is ideal for standard OD finishing.

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.
