LNHU100508-F57T WKP25S rectangular milling insert – Tiger·tec Silver grade by Walter Tools

The LNHU100508-F57T WKP25S is a rectangular milling insert designed for productive machining of steel and cast iron, offering high process stability and optimised chip formation.

• Tiger·tec Silver coating for enhanced wear resistance
• Optimised F57T chipbreaker for stable chips
• Rectangular form with 0.8 corner radius
• Negative 0° clearance for secure cutting

Greater uptime through proven coating and grade

The combination of the Tiger·tec Silver coating with the WKP25S carbide grade delivers extended tool life and predictable wear behaviour, which translates directly into longer uninterrupted production runs. The coating reduces abrasive wear on the cutting edge, while the grade is tuned for the heat and chip conditions encountered in machining steel and cast iron. For production engineers this means fewer tool changes and a cleaner planning horizon for machining cycles, improving overall efficiency and lowering per-part costs.

Stable cutting and reproducible chip control for consistent surfaces

The insert’s F57T chipbreaker is engineered to form short, controlled chips when cutting P- and K-group materials. The rectangular shape combined with a 0.8 corner radius and a 0° (negative) clearance angle provides robust edge support and reduced vibration during milling passes. The result is a consistent surface finish and reliable dimensional control across batches. For less experienced staff, the chipbreaker’s geometry simplifies process setup by reducing sensitivity to slight feed or speed variations.

Practical application, compatibility and process benefits

This insert is suitable for a wide range of milling operations where machining steel and cast iron is required; the designation adheres to ISO material groupings P and K for straightforward process selection. The geometry and coating make it well suited to both roughing operations that demand high material removal rates and semi-finishing where surface quality matters. As part of a systematic tooling strategy with matching toolholders, the insert supports predictable cycle times and consistent tool life, enhancing shop-floor planning and inventory control.

FAQ

What materials is this insert intended for?
The insert is specified for steel (ISO group P) and cast iron (ISO group K); the WKP25S grade and Tiger·tec Silver coating are optimised for those material groups.

How does the F57T chipbreaker affect machining?
The F57T chipbreaker produces short, controlled chips that improve chip evacuation and reduce the risk of built-up edge, supporting stable cutting and consistent surface quality.

Can this insert be used for finishing passes?
Yes, the insert’s geometry and 0.8 corner radius allow semi-finishing and certain finishing applications where a balance between tool life and surface quality is required.

Which series and grade does this insert belong to?
This insert is part of the Tiger·tec Silver series and uses the WKP25S carbide grade, combining coating technology with a carbide substrate tuned for machining steel and cast iron.
