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
