Grade: NX2525 Cermet Excellence
The NX2525 grade is a premium uncoated cermet. Cermets (Ceramic + Metal) are chemically inert, meaning they do not react with steel at high temperatures. This prevents crater wear and adhesion, allowing the TCMT090204 to maintain its sharp edge. It is the premier choice for high-speed finishing where a glossy surface finish is mandatory.
Chipbreaker: General Purpose Finishing
Designed for light depths of cut, this geometry provides excellent chip evacuation. It prevents "bird-nesting" during long finishing passes on small diameters, ensuring your workpiece remains scratch-free and your CNC cycle remains uninterrupted.

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.
