LNGX130712R-L55 WKP25S milling insert (Tiger‑tec Silver) — for Stahl and cast iron | Walter Tools

A LNGX130712R-L55 WKP25S milling insert engineered for robust engagement and reliable chip control in demanding milling operations on Stahl and cast iron.

• Tiger‑tec Silver coating for extended wear life
• WKP25S grade for broad material coverage
• Negative rake 0° for heavy-duty engagement
• 1.2 mm corner radius for secure edge stability

Maximise uptime through wear‑resistant coating and grade

The Tiger‑tec Silver coating combined with the WKP25S carbide grade is designed to reduce flank and crater wear under the thermal and mechanical loads typical of milling Stahl and cast iron. Coating technology improves abrasion resistance and helps to prevent premature edge breakdown; as a result, tool change frequency is lowered and productive machining time is increased. For operations that demand repeatable results, this configuration supports consistent surface quality and process stability.

Reliable machining performance and chip control

Equipped with an L55 chipbreaker and a rectangular geometry, this indexable plate ensures controlled chip formation during roughing and semi‑finishing passes. The 0° negative rake provides robust cutting edge engagement where rigidity is required, while the 1.2 mm corner radius increases edge strength to withstand intermittent cuts. These features combine to give predictable forces and manageable chips, simplifying coolant and chip management in the machining cell.

Suitable applications and installation guidance

The insert is specified for machining applications within the ISO groups P and K, meaning it is suitable for a wide range of Stahl grades and for cast iron components. Its designation and tolerance class support compatibility with standard milling toolholders designed for the LNGX form factor. When selecting cutter bodies, attention to seat geometry and clamping torque is advised so that the plate seating and cutting edge geometry deliver the intended performance and repeatability.

FAQ

What materials is the insert suitable for?
The LNGX130712R-L55 WKP25S insert is suitable for ISO groups P and K, explicitly covering a wide range of Stahl grades and cast iron applications.

How does the Tiger‑tec Silver coating affect performance?
The Tiger‑tec Silver coating on the WKP25S grade increases abrasion resistance and thermal stability, which extends tool life and maintains surface finish over longer machining cycles.

What is the effect of the 0° negative rake on cutting behaviour?
A 0° negative rake produces a more robust cutting edge that tolerates heavy engagement and unstable cutting conditions, making the insert suitable for demanding milling tasks where rigidity is essential.

Which chipbreaker is integrated and why is it important?
The insert features the L55 chipbreaker, designed to produce short, controllable chips and to improve evacuation when machining Stahl and cast iron, aiding process reliability and shop‑floor safety.
