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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
