NX2525 Cermet Grade
The NX2525 Cermet is a titanium-based material that provides high hardness and excellent thermal stability. It is specifically designed to prevent built-up edge (BUE), making it a critical long-tail precision tool for high-tolerance automotive and aerospace components requiring a glossy finish.
2G Chipbreaker Advantage
The 2G chipbreaker is a G-class finishing geometry. It features a specialized rake to maintain sharpness while ensuring consistent chip evacuation. This is the go-to geometry for lathe turning when the depth of cut is light but dimensional accuracy is non-negotiable.
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.
