NX2525 Cermet Advantage
The NX2525 grade is Mitsubishi's premier Cermet. Unlike standard carbide, cermet has a low affinity for metal-to-metal bonding, which effectively eliminates built-up edge (BUE). This property is crucial for lathe turning operations requiring tight dimensional tolerances and a high-gloss finish.
FS Chipbreaker Technology
The FS chipbreaker is a G-class super-finishing geometry. It features an ultra-sharp rake and positive angle to minimize cutting resistance. It excels at chip evacuation during very light depths of cut, ensuring no "birds-nesting" occurs in internal boring cycles.

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.
