Mitsubishi Materials | High-Speed Cermet Finishing Specialist
Mirror-Like Precision with Cermet Technology
The Mitsubishi TPMN110304 NX2525 is a high-performance Cermet turning insert designed for the ultimate surface finish. The NX2525 grade combines the hardness of ceramics with the toughness of metal, making it exceptionally resistant to oxidation and built-up edge. This uncoated cermet specialist is the industry standard for high-gloss finishing of carbon and alloy steels, ensuring your final parts meet mirror-quality specs and tight tolerances.

NX2525 Cermet Advantage
The NX2525 Cermet grade is specifically optimized for steel finishing. Because Cermet has a low affinity for steel, it effectively prevents material welding (BUE) on the cutting edge. This leads to a significantly longer tool life during high-speed finishing operations and provides a vastly superior surface luster compared to standard tungsten carbide.
TPMN Flat-Top Precision
The TPMN series features a flat-top (no chipbreaker) design. This is often preferred in stable finishing environments where the material creates manageable chips naturally at high speeds. It offers a strong, sharp edge for precision boring and light finishing passes where consistency is the top priority.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Mild/Carbon Steel | 150 - 350 m/min | 0.05 - 0.15 mm/rev | 0.1 - 1.2 mm |
| Alloy Steel | 120 - 280 m/min | 0.05 - 0.12 mm/rev | 0.1 - 1.0 mm |
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.
