LNHU090412R-L55T WKP35G — indexable milling insert for steel and cast iron (Walter Tools), Tiger‑tec Gold, 0° negative rake

LNHU090412R-L55T WKP35G is a rectangular indexable milling insert engineered for demanding milling operations in steel and cast iron, combining a coated‑carbide grade with a dedicated chipbreaker for reliable chip control and extended tool life.

• Tiger‑tec Gold coating extends tool life
• Optimised for steel and cast iron machining
• 0° negative rake for robust cutting
• Corner radius 1.2 mm for consistent surface finish

Reliable cutting performance through advanced grade and coating

The WKP35G grade, implemented within the Tiger‑tec Gold technology, is a coated carbide solution designed for high process stability and improved resistance to abrasive wear. This combination reduces flank and crater wear during continuous and interrupted cuts, delivering longer tool life and fewer index changes. The included L55T chipbreaker is tailored to the grade’s wear behaviour, improving chip control when machining typical ISO P and ISO K groups, which translates into higher machining uptime and more predictable tool costs per component.

Geometry optimised for stability and surface quality

A rectangular insert form with a 0° negative rake provides a robust cutting geometry that stands up to heavy engagement and interrupted cuts. The corner radius 1.2 mm helps absorb cutting forces and contributes to a consistent surface finish on every pass, while the plate thickness and size code ensure precise clamping and repeatable positioning in the toolholder. These geometric attributes support both roughing and semi‑finishing strategies, permitting higher material removal rates with reduced vibration and a stable cutting edge for repeatable component quality.

Application guidance and process advantages

The insert is specified for machining in steel (ISO P) and cast iron (ISO K), making it suitable for a broad range of general engineering applications where a balance of wear resistance and edge stability is required. The tolerance classification H indicates consistent manufacturing accuracy for predictable assembly and runout control. For process planning, pairing this grade with suitable spindle speeds and feed per tooth adapted to the workpiece material will realise the benefits of the coated substrate and chipbreaker design, reducing rework and improving overall productivity.

FAQ

Is this insert suitable for stainless steel applications?
The data for the LNHU090412R-L55T WKP35G insert indicates suitability for steel (ISO P) and cast iron (ISO K); stainless steel is not specified for this grade.

What advantages does the Tiger‑tec Gold technology provide?
Tiger‑tec Gold offers a coated‑carbide structure that improves wear resistance, edge stability and process security, leading to longer tool life for the LNHU090412R-L55T WKP35G insert in applicable materials.

Which chipbreaker is incorporated and what is its purpose?
The insert uses the L55T chipbreaker, which is designed to enhance chip formation and evacuation, reducing the risk of built‑up edge and improving surface quality during milling.

How does the 0° negative rake affect cutting behaviour?
A 0° negative rake produces a stronger cutting edge and better resistance to edge chipping, making the insert more robust in heavy or interrupted cuts while maintaining dimensional stability.
