Mitsubishi Materials | The Mirror-Finish Cermet Specialist
Precision Finishing for Carbon & Alloy Steels
The Mitsubishi VBMT160404-MV NX2525 is a 35° diamond Cermet turning insert engineered for ultra-high-speed finishing. The NX2525 grade is a non-coated Cermet that offers exceptional chemical stability, preventing the workpiece material from welding to the edge. With the MV (Medium-V) chipbreaker and a sharp 0.4mm corner radius, this long-tail finishing insert is the industry standard for achieving superior dimensional accuracy and mirror-like surface textures in CNC steel turning.

NX2525 Cermet Advantage
Cermet (Ceramic-Metal) grades like NX2525 provide high wear resistance and a low affinity for steel. Unlike tungsten carbide, cermet does not suffer from adhesive wear at high speeds. This ensures that the cutting edge remains sharp for longer periods, resulting in consistent surface finish quality and precise tolerances across long production runs in Carbon and Alloy steels.
MV Medium-V Chipbreaker
The MV chipbreaker on a cermet substrate is a powerful combination. It is designed to control chips during finish-to-medium profiling. The 16mm edge ($VBMT 331$) provides the stability needed for deep profiling, while the MV geometry curls and breaks chips even at the higher cutting speeds ($v_c$) typically used with cermet tooling.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |

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.
