SEMT13T3AGSN-JM NX4545
Mitsubishi Materials | The Mirror-Finish Cermet Specialist
The Mitsubishi SEMT13T3AGSN-JM NX4545 is a high-performance cermet milling insert engineered specifically for precision finishing. Utilizing the advanced NX4545 cermet grade, this insert excels in producing superior mirror surface finishes on carbon and alloy steels. Its high resistance to oxidation and low affinity for steel prevents built-up edge (BUE), making it the premier choice for high-speed CNC milling where aesthetic quality and dimensional precision are critical.

NX4545 Cermet Advantage
The NX4545 grade is a specialized cermet (TiCN-based) material. Unlike standard carbide, it possesses a low chemical affinity for ferrous metals, which virtually eliminates "chip welding." It maintains high hardness at extreme cutting temperatures, allowing for high-speed finishing of steel while providing long tool life and an exceptional gloss on the workpiece.
JM General-Purpose Finishing
The JM chipbreaker is the optimized choice for light to medium cutting. It balances a sharp cutting edge with a reinforced land, providing smooth chip evacuation and reducing cutting resistance. This ensures that the cermet substrate is protected from vibration, leading to a more stable surface finish and predictable wear patterns.

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.
