LNMU100508-F57T WKP25S milling indexable insert by Walter Tools — coated carbide grade for steel and cast iron machining

LNMU100508-F57T WKP25S is a rectangular milling insert designed for robust, repeatable performance in general steel and cast iron applications

• Tiger·tec Silver coated for extended life
• Optimised chip control with F57T chipbreaker
• Rectangular 10 mm form with 0.8 mm radius
• Suited for steel and cast iron machining

Stable wear behaviour reduces machining interruptions

The WKP25S grade, realised in the Tiger·tec Silver family, combines a hard, wear-resistant coating with a tough substrate to reduce flank and crater wear during continuous operation. This engineering reduces unscheduled tool changes and contributes to a higher overall equipment effectiveness (OEE). For machining tasks in the steel and cast iron groups the grade is tuned to the typical heat and chip characteristics of these materials, which results in predictable tool life and lower per-part tooling cost.

Precise chip control for improved surface quality

The dedicated F57T chipbreaker is engineered to control chip form in interrupted and continuous cuts, which eases evacuation and minimises recutting of chips. The rectangular geometry combined with a 0.8 mm corner radius supports stable cutting edges and consistent surface finish on workpieces, while the negative 0° rake provides edge strength for tougher engagement conditions. The result is less manual deburring and reduced downstream processing, supporting faster cycle times and improved part quality.

Series integration for efficient production planning

Produced to tolerance class M and available in the Tiger·tec Silver series, this insert supports standardisation across tool inventories and predictable replacement intervals. The clear size designation and chipbreaker coding simplify automatic bill-of-materials and tool-life tracking, enabling leaner stock levels and faster changeovers in high-mix production. Where catalogue-dependent geometry applies, the insert offers a balance of process reliability and adaptability for a wide range of turning and face-milling tasks.

FAQ

What materials is this insert suitable for?
The LNMU100508-F57T WKP25S insert from Walter Tools is specified for steel (P) and cast iron (K) machining according to the grade characteristics.

How does the Tiger·tec Silver coating help in production?
The Tiger·tec Silver coating on the WKP25S grade increases wear resistance and thermal stability, which supports longer tool life and more consistent component quality under continuous cutting.

What effect does the F57T chipbreaker have on chips?
The F57T chipbreaker promotes controlled chip segmentation and evacuation, reducing the risk of chip entanglement and improving surface finish when using the LNMU100508-F57T WKP25S insert.

Is the 0.8 mm corner radius suitable for finishing?
A 0.8 mm corner radius offers a compromise between edge strength and surface quality; with the WKP25S grade this supports both robust roughing and good surface integrity in many milling operations.

Can this insert handle interrupted cuts?
Yes, the rectangular form, negative rake geometry and the WKP25S grade combine to provide edge strength suitable for conditions with intermittent engagement.
