Grade: NX2525 Cermet
NX2525 is a high-purity uncoated cermet grade. By combining ceramic stability with metallic toughness, it provides an extremely sharp edge that stays keen longer than traditional carbide when finishing steel. Its resistance to chemical wear makes it ideal for high-speed CNC turning without the risk of workpiece smearing.
0.8mm Radius Strength
The 0.8mm nose radius ($RE$) significantly improves edge strength compared to the 0.4mm version. This allows for higher feed rates and greater stability during continuous cuts. The TCMT positive geometry ensures lower cutting forces, which is essential for indexable finishing inserts in light machining applications.
Recommended Cutting Data

|---|---|---|---|
| Low Carbon Steel | 150 - 350 m/min | 0.10 - 0.25 mm/rev | 0.2 - 1.5 mm |
| Alloy Steel | 120 - 280 m/min | 0.08 - 0.20 mm/rev | 0.2 - 1.2 mm |

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.
