Mitsubishi Materials | High-Speed Finishing Cermet Specialist
The Mitsubishi TNMG160408R-2G NX2525 is a premium Cermet turning insert engineered for high-speed finishing and semi-finishing applications. Unlike traditional carbide, the NX2525 Cermet grade offers superior resistance to oxidation and chemical wear, resulting in a mirror-like surface finish. This indexable turning insert features the 2G chipbreaker in a Right-Hand (R) orientation, providing unmatched chip control for CNC machining of carbon and alloy steels.

NX2525 Cermet Grade
The NX2525 Cermet is a titanium-based material that provides high hardness and excellent thermal stability. It is specifically designed to prevent built-up edge (BUE), making it a critical long-tail precision tool for high-tolerance automotive and aerospace components requiring a glossy finish.
2G Chipbreaker Advantage
The 2G chipbreaker is a G-class finishing geometry. It features a specialized rake to maintain sharpness while ensuring consistent chip evacuation. This is the go-to geometry for lathe turning when the depth of cut is light but dimensional accuracy is non-negotiable.

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.
