Mitsubishi Materials | The Specialist for High-Gloss Steel Finishing
Achieve Mirror-Quality Surfaces
The Mitsubishi TPMN110308 NX2525 is a high-speed Cermet turning insert engineered for precision finishing. The NX2525 grade is a non-coated cermet that provides exceptional chemical stability, effectively preventing Built-Up Edge (BUE). With its 0.8mm corner radius, this long-tail finishing tool provides a robust cutting edge capable of producing high-gloss surface finishes on carbon and alloy steels while maintaining strict dimensional tolerances during CNC boring.

NX2525 Micro-Grain Cermet
NX2525 is a cermet grade that bridges the gap between traditional carbide and ceramics. It features high resistance to plastic deformation and thermal shock. Because it contains metallic binders like nickel, it is tougher than pure ceramics but much harder than carbide, making it the perfect high-speed turning insert for steel finishing.
TPMN Flat-Top Advantage
The TPMN geometry features a flat-top face (no chipbreaker). This provides a stronger cutting edge for stable finishing passes. In high-speed steel turning, the chips naturally break or flow away easily; the absence of a chipbreaker reduces heat concentration at the tip, extending insert tool life.

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.
