Mitsubishi Materials | The High-Speed Cermet Specialist
The Mitsubishi TNGG160408R-F NX2525 is a high-performance cermet turning insert designed for high-speed finishing operations. Utilizing the advanced NX2525 titanium-cermet grade, this insert provides superior chemical stability and resistance to oxidation compared to standard carbide. Combined with the F chipbreaker, it is the ultimate choice for precision turning of carbon and alloy steels where a mirror-like surface finish is mandatory.

NX2525 Cermet Grade
The NX2525 grade is a specialized cermet (ceramic-metal composite) that offers extremely low chemical affinity for steel. This prevents "smearing" at high cutting speeds, ensuring that this indexable turning insert delivers unmatched surface brightness and sharp-edge retention during high-speed finishing.
F Chipbreaker (Fine Machining)
The F chipbreaker is specifically designed for ultra-light depths of cut. Its geometry optimizes chip evacuation even in softer steels, preventing long tangled chips from damaging the mirror-like finish of the workpiece. This right-hand (R) model is ideal for standard OD finishing.
