LNHU130612R-L55T WKP35G Fräswendeschneidplatte — Tiger‑tec Gold, for steel and cast iron (Walter Tools)

The LNHU130612R-L55T WKP35G is a rectangular milling indexable insert engineered for efficient removal of material in steel and cast iron applications, combining Walter Tools' Tiger‑tec Gold coating with a chipbreaker optimised for consistent chip control

• Tiger‑tec Gold coating for extended tool life
• WKP35G grade optimised for steel and cast iron
• Rectangular geometry with 1.2 mm corner radius
• 0° negative rake with L55T chipbreaker

Extended life and wear resistance for demanding turning and milling

The combination of Tiger‑tec Gold coating and the WKP35G coated-carbide grade delivers a measurable improvement in wear resistance and edge stability under typical steel and cast-iron cutting conditions. The coating technology reduces abrasive wear and heat-related edge degradation, which translates into longer intervals between indexings and fewer tool changes. Designed with ISO 513 workpiece groups in mind, this grade is adapted to the thermal loads and chip behaviour characteristic of steel (P) and cast iron (K). The result is predictable performance across a broad range of geometries and cutting speeds, supporting higher process reliability and lower overall tooling costs.

Consistent chip control and surface quality through geometry

The rectangular plate form and the L55T chipbreaker are matched to provide controlled chip formation and evacuation during interrupted and continuous cuts. A 0° negative rake contributes to a robust cutting edge that resists chipping under heavy engagement, while the 1.2 mm corner radius helps distribute cutting forces to improve surface finish and reduce notch wear. These geometric features support stable machining conditions, minimise secondary machining steps and aid in achieving repeatable dimensional results. For production environments where cycle time and component quality are both critical, this geometry offers a balance between cutting strength and finished-surface integrity.

Productivity gains and process security for batch production

Using this insert in the Tiger‑tec Gold series supports higher material removal rates and predictable tool life, which helps to shorten cycle times and increase throughput. The WKP35G grade and coating combination is designed to maintain a stable cutting edge, allowing for consistent feed and speed settings across multiple workpieces. That stability reduces setup variance and contributes to overall process security. Paired with the correct toolholder and machining parameters, the insert enables economical, repeatable machining in small to medium batches — a pragmatic choice for workshops seeking a robust, high‑performance solution from Walter Tools.

FAQ

What materials is this insert suitable for?
The LNHU130612R-L55T WKP35G insert is specified for steel (P) and cast iron (K), reflecting the WKP35G grade and the Tiger‑tec Gold coating designed for these ISO workpiece groups.

How does the Tiger‑tec Gold coating benefit machining?
Tiger‑tec Gold on this insert reduces abrasive wear and improves edge stability under thermal load, extending tool life and supporting consistent performance when machining steel and cast iron.

What is the effect of the 0° negative rake on cutting performance?
A 0° negative rake gives the insert a robust cutting edge that tolerates heavy engagement and intermittent cutting, increasing resistance to chipping and enhancing process security.

Which chipbreaker is fitted and what advantage does it provide?
The insert features the L55T chipbreaker, which is optimised for controlled chip formation and evacuation, helping to maintain surface quality and reduce the risk of chip-related interruptions.

Are there recommended applications for the rectangular geometry and 1.2 corner radius?
The rectangular form with a 1.2 corner radius is well suited to operations requiring strength at the cutting edge and improved surface finish, making it a solid choice for general milling tasks in steel and cast iron.
