NX2525 Cermet Advantage
The NX2525 Cermet grade is designed for high-speed finishing. Unlike standard carbide, cermet has a low affinity for steel, which eliminates built-up edge (BUE). This property is crucial for lathe turning operations requiring tight dimensional tolerances and a high-gloss finish.
FS "Super-Finish" Breaker
The FS chipbreaker features an ultra-sharp rake and positive geometry. It excels at chip evacuation during very light depths of cut, ensuring no "birds-nesting" occurs in internal boring cycles or fine external turning.

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.
