CNHQ0805PPN-A57T WKP35S — Fräswendeschneidplatte for Steel and Cast Iron | Walter Tools

The CNHQ0805PPN-A57T WKP35S is a rhombic 80° milling insert engineered for high‑productivity roughing and finishing of steel (ISO group P) and cast iron (ISO group K)

• Tiger‑tec Silver coating for extended tool life
• WKP35S grade for robust, repeatable cutting
• Rhombic 80° insert for versatile milling strategies
• Chipbreaker A57T for reliable chip control

Higher throughput through advanced coating and grade

The combination of the Tiger‑tec Silver coating and the WKP35S carbide grade delivers a clear productivity advantage in mixed‑batch and series production. The coating reduces adhesive wear and improves thermal resistance, while the substrate offers a robust cutting edge that maintains dimensional stability over longer tool life. For operations that require consistent cycle times, this means fewer insert changes and more uptime. The engineering of the coating and substrate is optimised for the thermal and mechanical demands of machining steel and cast iron, so the insert supports efficient chip formation and reduced flank wear during sustained use.

Geometry and chip control for predictable results

The rhombic 80° form combined with a 0° (negative) rake and the A57T chipbreaker promotes controlled chip flow and stable cutting forces, which benefits surface finish and process stability. This geometry suits a range of milling strategies, from shoulder milling to light contouring, and enables effective engagement angles on demanding features. The insert dimensions (size 08, thickness 05) and the tolerance class H support repeatable clamping and positional accuracy in indexable toolholders. For users transitioning between cast iron and steel components, the chip control characteristics reduce downtime related to chip evacuation and surface defects, translating into measurable process reliability.

Compatibility, handling and process support

As part of the Tiger‑tec Silver series, the insert is specified for ISO groups P (steel) and K (cast iron), making it suitable for a wide materials portfolio in general engineering and automotive workshops. The product comes in the execution marked Q and is identified as CNHQ0805PPN‑A57T WKP35S; compatible holders and tool systems should be selected according to the insert form and size. For application selection or cutting‑parameter recommendations, Metav Werkzeuge offers technical support to align feed and speed with workpiece requirements, ensuring a balance between productivity and tool life. The series design emphasises economical machining through stable chip formation and predictable edge behaviour.
