TNMU160508R-G57 WKP25S — indexable milling insert, Tiger‑tec Silver grade for steel and cast iron (Walter Tools)

A TNMU160508R-G57 WKP25S indexable milling insert engineered for high‑productivity milling of steel and cast iron in demanding production environments

• Tiger‑tec Silver coated WKP25S grade
• Triangle 60° geometry for secure seating
• 0.8 mm corner radius for robust cutting edges
• Optimised chip control with G57 chipbreaker

Consistent performance across steel and cast iron

The insert is designed for reliable machining of steel (P) and cast iron (K) according to ISO 513‑aligned applications. The combination of the WKP25S coated carbide grade and the Tiger‑tec Silver coating delivers stable wear behaviour and predictable tool life, which reduces process variability. By focusing on heat and chip formation typical for these material groups, the geometry and grade support consistent surface quality and repeatable cycle times on production runs.

Longer tool life through advanced coating technology

The Tiger‑tec Silver technology provides a balanced coating system that improves resistance to abrasive wear and thermal loading during milling. This results in fewer insert changes and longer intervals between tool interventions, contributing to lower machine downtime and higher overall equipment effectiveness. When paired with the WKP25S substrate, the system is tuned to manage the mechanical and thermal stresses encountered in mixed‑batch work, enabling a better cost‑per‑part ratio for medium to high volumes.

Geometry engineered for stability and repeatable results

The triangular 60° shape and the 0° negative relief create a rigid cutting configuration that supports interrupted and continuous cuts alike. The 0.8 mm corner radius strengthens the insert tip against chipping and provides a reliable cutting edge for semi‑finishing tasks. Tolerance class M and the insert’s form factor contribute to accurate seating in cutter bodies, which helps to maintain dimensional consistency and minimise rework.

Practical use and process support for efficient integration

The integrated G57 chipbreaker assists in predictable chip formation, improving evacuation and reducing the risk of built‑up edge in steel and cast iron applications. The insert is available in a compact size suited to a wide range of milling cutter bodies; consult Metav Werkzeuge for validated cutting data, recommended feeds and speeds, and tooling combinations to match the machining strategy. Technical advice and application support are available when process stability or surface finish are critical.

FAQ

What materials is this insert suitable for?
The TNMU160508R-G57 WKP25S insert is intended for machining steel (P) and cast iron (K) as indicated by its WKP25S grade and Tiger‑tec Silver coating.

How does the Tiger‑tec Silver coating benefit production?
Tiger‑tec Silver on the WKP25S grade improves abrasive and thermal wear resistance, extending tool life and supporting more consistent cycle times in milling operations.

What is the effect of the 0.8 mm corner radius?
A 0.8 mm corner radius increases edge robustness, reducing the likelihood of chipping and enabling stable semi‑finishing passes with good surface quality.

Which chip behaviour can be expected with the G57 chipbreaker?
The G57 chipbreaker promotes controlled chip formation for improved evacuation in interrupted and continuous cuts, enhancing process reliability when machining P and K materials.

Where can validated cutting data and tooling recommendations be obtained?
Validated cutting parameters and tooling pairings are available from Metav Werkzeuge; refer to application specialists for cutter body compatibility and optimisation.
