LNGX130708R-L55 WKP35G milling insert — rectangular, Tiger‑tec Gold, 0° negative — Walter Tools

The LNGX130708R-L55 WKP35G is a rectangular milling insert engineered for productive machining of steel and cast iron, combining a coated‑carbide grade with a dedicated chipbreaker and a compact corner radius.

• Tiger‑tec Gold coated for wear resistance
• L55 chipbreaker for controlled chip formation
• Rectangular insert with 0° negative rake
• Suited for ISO P (steel) and ISO K (cast iron)

Consistent process reliability through advanced coating and grade

The combination of Tiger‑tec Gold technology and the WKP35G grade provides pronounced wear resistance and thermal stability under typical steel and cast‑iron cutting conditions. This coating stack is designed to reduce flank and crater wear, which translates into longer tool life and fewer insert changes. For production environments, that means higher uptime and a predictable tool‑change rhythm, supporting stable cycle times and repeatable component quality.

Optimised chip control and surface results from the L55 geometry

The L55 chipbreaker is engineered to produce short, controllable chips across a range of feed and depth settings, improving evacuation in both slotting and shoulder milling. Combined with the 0.8 mm corner radius, the geometry helps achieve a balance between edge strength and surface finish: the radius supports edge robustness while the chipbreaker reduces the risk of built‑up edge on cast parts. The result is a reliable surface quality with reduced rework and a lowered risk of workpiece damage.

Geometry and mounting benefits for robust machining

The rectangular shape with a 0° negative rake gives the insert mechanical stability and a consistent cutting edge orientation that suits interrupted cuts and heavy engagement. The compact plate thickness and precise tolerance class G ensure repeatable seating in standard toolholders, which contributes to steady tool performance and simplified inventory management. The insert’s form factor supports productive milling strategies where rigidity and repeatability are decisive.

Application scope and material compatibility

Designed for ISO groups P (steel) and K (cast iron), the grade and coating combination is tuned for the thermal loads and abrasive wear typical of these materials. The wrapped technical concept focuses on adaptable performance for a wide range of steels and grey or ductile cast irons, making the insert a versatile choice in mixed‑workshop environments where quick toolchange decisions and broad material coverage are required. The construction supports both finishing and medium‑duty roughing tasks when paired with appropriate cutting data.

FAQ

What materials is this insert suitable for?
The LNGX130708R-L55 WKP35G milling insert from Walter Tools is designed for machining ISO P (steel) and ISO K (cast iron), with the grade and coating optimised for those material groups.

How does the L55 chipbreaker affect performance?
The L55 chipbreaker on this insert promotes short, controllable chips that ease evacuation and reduce the likelihood of chip accumulation, improving process stability and surface finish in milling operations.

What does the 0° negative rake mean for cutting?
A 0° negative rake provides a mechanically robust cutting edge, better suited to interrupted cuts and higher engagement depths; the geometry helps maintain tool life under heavy loads.

Which benefits does the Tiger‑tec Gold series deliver?
Tiger‑tec Gold coating increases thermal resistance and wear protection, resulting in longer edge life and more predictable performance across a variety of steels and cast irons.

What is the corner radius and how does it influence results?
The corner radius of 0.8 mm offers a compromise between edge strength and surface quality, protecting the cutting edge while enabling good finishing characteristics.
