NX2525 Cermet Advantage
The NX2525 Cermet grade is specifically optimized for steel finishing. Because Cermet has a low affinity for steel, it effectively prevents material welding (BUE) on the cutting edge. This leads to a significantly longer tool life during high-speed finishing operations and provides a vastly superior surface luster compared to standard tungsten carbide.
TPMN Flat-Top Precision
The TPMN series features a flat-top (no chipbreaker) design. This is often preferred in stable finishing environments where the material creates manageable chips naturally at high speeds. It offers a strong, sharp edge for precision boring and light finishing passes where consistency is the top priority.

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.
