NX2525 Cermet Grade
The NX2525 grade is a specialized titanium-based cermet (ceramic-metal composite). It provides superior resistance to built-up edge (BUE) and crater wear. Unlike carbide, cermet has a low affinity for steel, making this indexable turning insert the premier choice for achieving high dimensional accuracy and exceptional brightness in the final pass.
Chipbreaker Technology
Standard TNMG geometry provides a balanced cutting edge for general-purpose stable turning. The double-sided design offers 6 usable cutting edges, maximizing cost-efficiency for high-volume CNC finishing applications. It excels in chip control across a wide range of feed rates.
Recommended Cutting Parameters
| Material Group | Cutting Speed ($v_c$) | Feed Rate ($f$) | Depth of Cut ($a_p$) |
|---|---|---|---|
| Carbon Steel / Alloy Steel | 150 - 350 m/min | 0.05 - 0.25 mm/rev | 0.2 - 2.0 mm |
| Stainless Steel (Finishing) | 100 - 250 m/min | 0.05 - 0.20 mm/rev | 0.2 - 1.5 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.
