TCGT060104L-F NX2525
Mitsubishi Materials | High-Precision Cermet for Mirror Finishing
The Mitsubishi TCGT060104L-F NX2525 is a high-grade cermet turning insert engineered for precision finishing where surface integrity is paramount. Utilizing the NX2525 uncoated cermet grade, this insert provides exceptional chemical stability, effectively preventing built-up edge (BUE) when machining carbon and alloy steels. The F-breaker geometry ensures superior chip control at light depths of cut, making it the ideal long-tail tool solution for high-gloss, high-tolerance components.

NX2525 Cermet Excellence
The NX2525 grade is a specialized uncoated cermet. Cermets offer higher chemical stability than standard carbide, which is critical for finishing steel. It maintains a sharp edge at high temperatures, ensuring that surface finishes stay consistent throughout the batch. It is the top choice for high-speed precision turning where a mirror-like gloss is the target.
F-Breaker Chip Control
The F-Breaker (Finishing Breaker) is meticulously designed for light cutting loads. It provides excellent chip evacuation even at very low feed rates, preventing workpiece scratches caused by long, stringy chips. The 0.4mm radius offers a perfect balance between edge strength and the ability to reach tight corners in internal boring.

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.
