LNGX130725R-L55 WKP35G milling indexable insert — Tiger‑tec Gold coated, for steel and cast iron (Walter Tools)

The LNGX130725R-L55 WKP35G is a rectangular milling insert engineered for reliable chip control and sustained performance when machining steel and cast iron.

• Tiger‑tec Gold coated for long life
• WKP35G grade for steel and cast iron
• L55 chipbreaker for controlled chips
• Rectangular insert with 2.5 corner radius

Boost cycle times with a robust grade and coating

The combination of Tiger‑tec Gold technology and the WKP35G grade provides a balance of wear resistance and thermal stability that translates into higher throughput and fewer tool changes. As a coated carbide solution, this insert resists abrasive wear typical for cast components while remaining stable under the heat generated when machining unalloyed and alloyed steel. The result is a productive cutting edge that contributes to lower overall machining costs and improved process reliability.

Maintain consistent chip control through dedicated geometry

The L55 chipbreaker is designed to promote predictable chip formation across a range of cutting depths, reducing the risk of snarled chips and tool interruption. Paired with the insert’s rectangular form and a 2.5 corner radius, the geometry supports robust entry conditions and even wear distribution. The 0° negative rake helps to strengthen the cutting edge for roughing operations, making the insert particularly suitable where edge stability and fracture resistance are priorities.

Clear application scope for planning and tooling

This insert is specified for machining groups P and K, i.e. steel and cast iron, and is therefore a practical choice for mixed-production workshops handling both material families. The design is compatible with indexable milling cutters that accept this rectangular format; selecting a matching cutter body and correct seat geometry ensures the insert’s performance advantages are realised. For production environments seeking predictable tool life and repeatable results, this insert provides an efficient, versatile option.

Confidence through manufacturing tolerances and series quality

Tolerance class G and the Tiger‑tec Gold series background indicate manufacturing consistency and reliable interchangeability. The insert’s execution and measurables — including plate size and thickness — align with standard cutter systems that accept the LNGX series geometry. This predictability simplifies tool inventory management and reduces setup variability, supporting steady production flow and easier quality control.

FAQ

What materials is this insert intended for?
The LNGX130725R-L55 WKP35G from Walter Tools is intended for machining steel and cast iron, corresponding to the P and K ISO material groups, and is optimised for the chip and wear behaviours typical of those materials.

What advantages does the WKP35G grade provide?
The WKP35G grade, part of the Tiger‑tec Gold range, delivers enhanced wear resistance and stable cutting performance through its coated carbide construction, supporting longer tool life under mixed production loads.

How does the L55 chipbreaker influence machining?
The L55 chipbreaker promotes short, controlled chips and consistent breakage across varied cutting parameters, which reduces rework time and improves process security during interrupted cuts or heavy roughing.

Which geometry features deliver reliable performance?
Reliable performance is supported by the rectangular form, 2,5 corner radius and 0° negative rake, combined with tolerance class G, which together ensure a robust edge, predictable wear, and straightforward indexing.
