CNHU0805PPN-D57T WKP25S — Milling insert (Tiger‑tec Silver) for steel & cast iron by Walter Tools

The CNHU0805PPN-D57T WKP25S is a coated carbide milling insert engineered for productive machining of steel and cast iron, offering a robust geometry and a coating system optimised for long tool life.

• Tiger‑tec Silver coating for long tool life
• Designed for steel and cast iron machining
• Rhombic 80° geometry, 0° negative rake
• Coated carbide, stable chip formation

High-performance coating that extends runtime and reduces cost per part

The combination of the Tiger‑tec Silver technology with the WKP25S grade provides a wear-resistant surface that translates into longer tool life and fewer indexings. The coating is a multi-layer system optimised to reduce flank wear and resist abrasive conditions commonly encountered when machining cast components. For production environments this means improved process reliability and a lower cost per finished piece, as downtimes for tool changes are reduced and consistent surface quality is maintained.

Geometry designed for stable cutting and predictable chip control

The rhombic 80° plate form together with the 0° (negative) relief angle gives a favourable balance between cutting edge strength and accessibility in shoulder milling or trochoidal operations. This geometry supports stable chip formation, particularly when paired with the plate’s D57T chipbreaker, which is tailored to break chips reliably in both short and semi-continuous forms. The result is smoother material evacuation and reduced risk of re-cutting chips, supporting faster cycle times without sacrificing component integrity.

Application range and material compatibility explained

This indexable plate is specifically prepared for machining tasks classified under ISO P (steel) and ISO K (cast iron). That means the substrate and coating system cope with the thermal loads and abrasive wear typical for these groups. When selecting cutting parameters, the plate’s characteristics favour feeds and speeds that exploit its coating and chipbreaker design — leading to consistent surface quality and repeatable cycle results across batch productions.

Integration into production and operational benefits

Tolerance class H, plate size 08 and thickness 05 ensure reproducible seating in standard toolholders while providing the mechanical robustness needed in demanding machining contexts. The use of a coated carbide grade reduces the frequency of tool exchanges and supports high‑rate machining strategies. Combined with the proven heritage of Walter Tools, the insert provides dependable performance for workshops seeking a predictable and productive milling solution.
