GY2M0300F020N-MS NX2525
Mitsubishi Materials | Premium Cermet Grooving Series
The Mitsubishi GY2M0300F020N-MS NX2525 is a high-performance 3.0mm width grooving insert designed for the modular GY Series tool system. Unlike standard carbide, this insert utilizes the NX2525 Cermet grade, which provides exceptional chemical stability and oxidation resistance. Combined with the MS chipbreaker (Medium-Low Feed), it is the ultimate solution for achieving a mirror-like surface finish in steel and carbon steel applications.

| Material Grade | NX2525 (High-Performance Cermet) |
NX2525 Cermet Grade
The NX2525 grade is a cermet (Ceramic + Metal) material that offers superior resistance to built-up edge (BUE). Because cermet does not have a high affinity for steel, it produces significantly better surface gloss and dimensional accuracy than coated carbide in finishing operations.
MS Chipbreaker Advantage
The MS (Medium-Low Feed) chipbreaker is specifically tuned for precision profiling and grooving. It facilitates smooth chip breaking even at low feed rates, preventing long tangles that can damage the workpiece surface finish during high-speed finishing.

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.
