NX2525 Grade & F-Breaker Detail
NX2525 Cermet Grade: Cermet (Ceramic-Metal) grades are the industry secret for high-speed finishing. NX2525 is a non-coated cermet that provides excellent wear resistance and thermal stability. It effectively prevents metal from welding to the tip, ensuring a high surface finish even during long production runs.
F-Breaker (Finishing): The F-type chipbreaker is specifically ground for low depths of cut and light feed rates. It provides exceptional chip control, preventing long, stringy chips from damaging the delicate finished surface of your CNC lathe components.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Carbon Steel | 150 - 350 m/min | 0.03 - 0.12 mm/rev | 0.1 - 0.8 mm |
| Alloy Steel | 100 - 250 m/min | 0.03 - 0.10 mm/rev | 0.1 - 0.5 mm |

NX2525 is the king of finishing steel. However, if your work involves interrupted cutting or stainless steel machining, consider switching to VP15TF (PVD Carbide) for higher toughness. For high-speed production of cast iron, the UC5115 CVD grade is recommended.

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.
