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.
