Mitsubishi Materials | High-Speed Cermet Finishing Specialist
Ultra-Gloss Profiling & High-Precision Finishing
The Mitsubishi VBGT110302R-F NX2525 is a high-precision 35° diamond cermet turning insert engineered for ultra-fine surface finishes. The NX2525 grade is a titanium-based cermet that provides exceptional wear resistance and prevents chemical sticking (Built-Up Edge). Featuring the F-type chipbreaker and a sharp 0.2mm corner radius, this long-tail precision insert is designed for the high-speed finishing of carbon and alloy steels where a mirror-like shine is required.

NX2525 Cermet Excellence
The NX2525 grade is Mitsubishi's flagship Cermet material. Because it is chemically inert to iron, it virtually eliminates the risk of Built-Up Edge (BUE), which is the primary cause of poor surface finish. It maintains its edge sharpness much longer than standard carbide at high speeds, making it the industry standard for mirror-finishing steel.
F-Type Chipbreaker (Fine Finish)
The F-type chipbreaker is designed for "Light-to-Fine" finishing. Its sharp geometry and narrow rake face provide stable chip control even at exceptionally low depths of cut ($a_p$ < 0.5mm). This ensures that delicate profiles aren't marred by long, stringy chips during precision CNC profiling.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Carbon Steel (1045) | 150 - 300 m/min | 0.03 - 0.10 mm/rev | 0.1 - 0.8 mm |
| Alloy Steel (4140) | 120 - 250 m/min | 0.03 - 0.08 mm/rev | 0.1 - 0.5 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.
