LNHU130625R-L55T WKP35G Milling indexable insert — Tiger‑tec Gold, for steel and cast iron (Walter Tools)

LNHU130625R-L55T WKP35G is a rectangular milling insert engineered for medium‑ to heavy‑duty finishing and roughing operations in steel and cast iron, featuring the Tiger‑tec Gold coating and a dedicated L55T chipbreaker

• Tiger‑tec Gold coating for extended tool life
• WKP35G grade for steel and cast iron
• Rectangular insert with 2.5 mm corner radius
• L55T chipbreaker geometry for reliable chip control

Consistent productivity through advanced coating and grade

The Tiger‑tec Gold coating combined with the WKP35G grade provides a balanced solution for frequent, economical machining cycles. Coated carbide technology reduces abrasive wear and supports stable cutting-edge behaviour when machining group P (steel) and group K (cast iron) materials according to ISO designations. This insert’s coating system is tailored to maintain edge integrity under the thermal and mechanical loads typical of steel turning and cast‑iron milling, translating into fewer tool changes and more predictable production output. The result is measurable productivity gains and lower process downtime.

Predictable chip control and surface quality for fewer reworks

Equipped with the L55T chipbreaker, the insert channels chips reliably for both continuous and segmented chip forms, reducing the risk of re-cutting and machine interruptions. The rectangular geometry and 2.5 mm corner radius support consistent tool engagement and help achieve stable surface finish on each pass. Combined with the 0° (negative) rake configuration, the insert excels in applications that demand robustness and resistance to edge chipping, ensuring repeatable part quality and reducing secondary finishing operations.

Application scope and process advantages

This cutting grade is optimised for machining unalloyed and alloyed steel as well as cast iron, offering broad material coverage for job shops and production environments alike. The design supports both high material removal rate operations and finishing passes when process parameters are adapted accordingly. By selecting the appropriate cutting speeds and feeds for the WKP35G grade, operators benefit from improved tool life and consistent dimensional results, which in turn supports tighter process control and lower total cost per component.

Practical integration and handling in production

The insert’s ISO‑style designation and standard rectangular form make it straightforward to integrate into existing toolholder systems that accept this geometry. Identification as a coated carbide insert simplifies tool management and reordering. For assembly, standard mounting practice applies; ensure the seat and clamp are clean and torque is set per the toolholder manufacturer’s guidance to secure repeatable runout and stable cutting conditions. When paired with optimised machining parameters, this insert contributes to a reliable, economical production process.

FAQ

What materials is this insert suitable for?
The LNHU130625R-L55T WKP35G insert (Walter Tools, Tiger‑tec Gold series) is designed for ISO group P (steel) and ISO group K (cast iron) machining.

How does the Tiger‑tec Gold coating benefit production?
The Tiger‑tec Gold coating on the WKP35G grade reduces abrasive wear and improves edge stability, which enhances tool life and supports stable process windows in steel and cast‑iron applications.

What is the function of the L55T chipbreaker?
The L55T chipbreaker promotes reliable chip formation and evacuation for a range of cutting conditions, helping to avoid re‑cutting and machine stoppages.

Can this insert be used for finishing passes?
Yes; when combined with appropriate cutting parameters the rectangular insert with a 2.5 mm corner radius delivers consistent surface quality suitable for finishing operations.

Is the 0° free angle suitable for interrupted cuts?
The 0° (negative) free angle provides increased edge strength and is advantageous in interrupted or heavy engagement cuts where chipping resistance is required.
