TCMT16T304 NX2525
Mitsubishi Materials | The Standard for Mirror-Finish Steel Turning
The Mitsubishi TCMT16T304 NX2525 is a high-performance turning cermet insert engineered for precision finishing operations. Utilizing the NX2525 uncoated cermet grade, this tool provides exceptional chemical stability and resistance to built-up edge (BUE), which is critical for achieving a mirror-like surface finish on carbon and alloy steels. As a preferred long-tail precision tool, it ensures high dimensional accuracy and long tool life in high-speed applications.

NX2525 Cermet Grade
The NX2525 grade is a specialized cermet (Ceramic-Metal composite). Unlike standard carbide, it has a low affinity for metal workpieces, which virtually eliminates built-up edge. It is designed specifically for high-speed finishing of steel, offering superior wear resistance and maintaining a sharp cutting edge for extended periods.
Optimized Chip Control
The TCMT geometry features a 7° positive relief angle, reducing cutting force and heat generation. This indexable finishing insert is optimized for light depths of cut, ensuring excellent chip evacuation and preventing workpiece scratching in long-run CNC production.
Recommended Cutting Data

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.
