TCMT110202 NX2525
Mitsubishi Materials | Ultra-Fine Mirror Finishing Specialist
The Mitsubishi TCMT110202 NX2525 is a high-precision turning cermet insert engineered for micro-finishing applications. By utilizing the NX2525 uncoated cermet grade, this insert provides superior chemical stability, effectively preventing the built-up edge (BUE) that ruins precision tolerances. It is the ultimate long-tail precision solution for achieving mirror-like surface finishes on carbon and alloy steels.

NX2525 Cermet Performance
The NX2525 grade is a specialized uncoated cermet (Ceramic-Metal composite). Unlike carbide, cermet is chemically stable at high speeds, which is the key to achieving super-high surface gloss. This grade is optimized for high-speed finishing of steel, offering excellent crater wear resistance and sharp edge retention over long production runs.
Ultra-Fine Geometry
The 0.2mm nose radius ($RE$) on this TCMT insert is designed for exceptionally light depths of cut. This minimizes cutting pressure, making it ideal for slender parts or internal boring where tool deflection must be avoided. It ensures precise chip control even at ultra-low feed rates.

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.
