XNMF090612-F57 WKP25S — Milling insert XNMF090612-F57 WKP25S, Tiger‑tec Silver, for steel & cast iron — Walter Tools

The XNMF090612-F57 WKP25S is a coated carbide milling insert designed for productive machining of steel and cast iron, combining robust chip control with a geometry optimised for reliable material removal.

• Tiger‑tec Silver coated grade WKP25S
• Optimised chip control with F57 breaker
• Negative 0° rake for reliable roughing
• Suitable for steel and cast iron machining

Boosted productivity through hardened coating technology

The combination of Tiger‑tec Silver coating and WKP25S grade yields a balance of wear resistance and toughness that supports longer cutting intervals and consistent surface finish. This coated carbide composition reduces flank wear under typical milling temperatures, making it well suited to continuous production environments where sustained cutting performance and component repeatability matter. The result is fewer tool changes and improved uptime on the shop floor.

Application-focused compatibility for common engineering materials

Engineered for the ISO P and K groups, this insert excels when machining steel and cast iron. The substrate and coating chemistry are tuned for the thermal and abrasive conditions typical of these materials, enabling controllable chip formation and predictable edge behaviour. For workshops producing structural components or cast parts, the geometry and grade provide a dependable solution for both roughing and mixed finishing operations.

Geometry designed for robustness and chip control

A 0° negative rake provides enhanced edge strength for interrupted cuts and heavy engagement, while the 1.2 mm corner radius contributes to improved insert life and more even wear distribution along the cutting edge. The integrated chipbreaker F57 promotes short, manageable chips that lower the risk of entanglement and improve machine and toolholder safety. Combined, these geometric features reduce the likelihood of edge chipping and support stable cutting forces during demanding operations.

Precision and interchangeability for process stability

Manufactured to tolerance class M with size 09 and thickness 06, the insert fits standard indexable milling cutter systems and enables repeatable positioning after index changes. The consistent manufacturing tolerance supports predictable machining results and easier toolpath optimisation. Together with the grade’s properties, this leads to stable chip formation and reliable surface quality across production batches, contributing to lower scrap rates and improved first‑pass yield.
