LNHU130608R-L55T WKP25S milling indexable insert – Tiger‑tec Silver, for steel & cast iron | Walter Tools

The LNHU130608R-L55T WKP25S is a rectangular milling insert designed for productive machining of steel and cast iron, featuring a Tiger‑tec Silver coating and a 0° negative rake for robust cutting performance

• Tiger‑tec Silver coating for edge stability
• Grade WKP25S for steel and cast iron
• Negative 0° rake for robust cutting
• 0.8 mm corner radius for edge strength

Higher throughput through a wear‑resistant grade

The combination of Tiger‑tec Silver technology and the WKP25S grade provides a wear‑resistant, coated carbide solution that is optimised for the ISO material groups P and K. This means the insert copes with the typical heat and chip formation of steels while also resisting the abrasive nature of cast iron. The result is consistent edge life and fewer unscheduled tool changes, which supports continuous production and predictable machining costs. Where process stability matters, this grade delivers reproducible results without complex intervention.

Reliable chip control that keeps the process running

Built with the chipbreaker L55T and a rectangular form, the insert promotes controlled chip formation and efficient evacuation during peripheral and face milling operations. The 0° rake (negative) gives the geometry robustness for interrupted cutting and heavy engagement, helping to avoid unstable cuts and tool damage. Better chip control reduces machine stoppages and makes coolant and chip‑conveyance strategies more effective, supporting a smoother workflow on the shop floor.

Robust geometry for repeatable surface quality

With a 0.8 mm corner radius and a defined tolerance class H, the insert offers a balance between edge strength and achievable surface finish. The insert's geometry maintains dimensional consistency across tool changes, aiding process repeatability and helping to meet tightening component tolerances. The combination of stable cutting edge and reliable dimensions supports both serial production and demanding one‑off components where reproducible results and minimal rework are required. The LNHU130608R‑L55T WKP25S is thus a practical choice for production environments that prioritise uptime and quality.

FAQ

What materials is this insert suitable for?
The LNHU130608R‑L55T WKP25S milling indexable insert from Walter Tools is specified for ISO groups P and K, i.e. steel and cast iron, and its WKP25S grade and Tiger‑tec Silver coating are adapted to those material behaviours.

How does the chipbreaker L55T affect machining?
The chipbreaker L55T on this insert promotes controlled chip formation and evacuation, which improves process stability and reduces the risk of recut chips during milling with the LNHU130608R‑L55T WKP25S insert.

What does the 0° rake mean in practice?
A 0° rake (negative) creates a robust cutting edge that tolerates heavier engagement and interrupted cuts; this geometry favours durability and secure cutting conditions with the Walter Tools insert.

Is the corner radius suitable for finishing?
The 0.8 mm corner radius on the insert increases edge strength while still allowing good surface quality in many general machining tasks; selection should be matched to the required surface finish and cutting parameters.

What does tolerance class H indicate for this insert?
Tolerance class H denotes the insert's dimensional specification and consistency; for the LNHU130608R‑L55T WKP25S this supports repeatable positioning and predictable results in fixture and toolholder setups.
