LNGX130708R-L55 WKP25S — Rectangular milling insert, Tiger‑tec Silver grade, for steel & cast iron | Walter Tools

LNGX130708R-L55 WKP25S is a coated indexable milling insert designed for robust performance in general milling of steel and cast iron components.

• Tiger‑tec Silver coating for long tool life
• Suitable for steel (P) and cast iron (K)
• Rectangular 13 mm insert, R0.8 corner
• L55 chipbreaker for stable chip control

Predictable performance thanks to the Tiger‑tec Silver grade

The WKP25S grade, developed within the Tiger‑tec Silver family, is a coated carbide variant optimised for the thermal and mechanical demands of steel and cast‑iron machining. The coating improves wear resistance and reduces flank and crater wear under cyclic loads, so cutting edges retain their geometry longer. In practical terms, this means fewer indexings and more consistent cycle times in production runs. The design is aimed at workshops and production facilities seeking a balance between cost efficiency and repeatable component quality.

Geometry and chip control that stabilise machining processes

The rectangular form with a corner radius R0.8 mm and the dedicated L55 chipbreaker deliver controlled chip formation and evacuation. The insert’s 0° (negative) rake setting promotes a robust cutting edge that is less prone to chipping under interrupted cuts or heavy engagement, making it suitable for moderate roughing and general‑purpose face milling where edge stability is critical. The combination of profile and chipbreaker reduces vibration and supports a predictable surface finish, thereby improving downstream processes like assembly or heat treatment.

Production integration and process reliability for series machining

Designed with a tolerance class G, this insert ensures repeatable seating and alignment in compatible indexable toolholders. The rectangular insert form and standardised dimensions facilitate quick replacement and minimise machine downtime. As a Walter Tools product from the Tiger‑tec Silver series, the insert is intended for industrial environments that prioritise process security and consistent output. For specific cutting data and holder compatibility, technical guidance is recommended to match speeds, feeds and depth of cut to the chosen workpiece and machining strategy.

FAQ

Which materials is this insert designed for?
The LNGX130708R-L55 WKP25S insert from Walter Tools is designed for machining steel (P) and cast iron (K), with the coating and grade tuned to handle the typical heat and chip characteristics of those groups.

What does the WKP25S grade indicate?
WKP25S denotes a Walter Tools coated‑carbide grade within the Tiger‑tec Silver technology, developed for high wear resistance and stable cutting-edge performance in steel and cast‑iron applications.

How does the L55 chipbreaker affect machining?
The L55 chipbreaker promotes short, controlled chips and reliable evacuation, which reduces the risk of built‑up edge and improves surface finish and process stability during continuous milling operations.

What is the significance of the 0° (negative) free angle?
A 0° (negative) free angle provides a robust cutting geometry that supports interrupted cuts and heavier engagements by strengthening the edge, which is beneficial for roughing and heavy milling passes.

Is this insert suitable for high‑speed milling?
The Tiger‑tec Silver coating and the WKP25S grade offer improved wear resistance; suitability for high‑speed milling depends on the specific machine, holder and cutting parameters, so performance should be validated with the chosen setup.
