NX2525 Cermet Grade
The NX2525 grade is a titanium-based cermet that provides high hardness and low chemical affinity with steel workpieces. Unlike standard carbide, it resists material "smearing" at high speeds. This ensures that the indexable turning insert maintains a sharp edge, resulting in superior surface brightness and dimensional accuracy during high-speed finishing.
F Chipbreaker (Fine Machining)
The F chipbreaker is specifically optimized for precision turning at light depths of cut. Its rake geometry ensures excellent chip evacuation even in ductile materials, preventing workpiece scratching. This right-hand (R) configuration is perfect for standard OD turning and facing operations.

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.
