NX2525 Cermet Technology
The NX2525 Cermet grade is a titanium-based material that offers exceptional resistance to oxidation and built-up edge (BUE). Cermet stays sharper longer than carbide at high speeds, making it the premier choice for lathe turning operations that require "as-polished" surface quality.
FS Chipbreaker Geometry
The FS chipbreaker is an ultra-sharp geometry optimized for super-finishing. It provides excellent chip control even at extremely low feed rates and shallow depths of cut, essential for high-precision components and light boring applications.
Recommended Cutting Parameters

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.
