LNHU080404-F57T WSM35G milling indexable insert – Tiger·tec Gold, 0° negative rake (Walter Tools)

The LNHU080404-F57T WSM35G is a rectangular milling indexable insert developed for robust chip control and edge stability during the machining of stainless steel and other difficult‑to‑cut alloys.

• Tiger·tec Gold coated cutting grade WSM35G
• Optimised chip control F57T geometry
• 0° negative rake, rectangular insert form
• 0.4 mm corner radius for robust edges

High‑performance coating for consistent machining results

The Tiger·tec Gold coating combined with the WSM35G grade provides a balance of heat resistance and wear protection that is especially beneficial when working with stainless steel and heat‑resistant superalloys. This coated cemented carbide composition supports a stable cutting edge under elevated temperatures and reduces the risk of build‑up on the tool flank. The result is a reproducible surface finish and predictable tool life, which simplifies process planning and reduces downtime caused by premature insert changes.

Optimised chip control and secure cutting geometry

The F57T chipbreaker geometry is engineered to produce controlled, segmented chips rather than long, tangled swarf, improving evacuation in interrupted cuts and deep pocketing. The combination of chipbreaker and the insert’s 0.4 mm corner radius maintains edge strength while enabling fine finishes in finishing passes. For milling operations requiring repeatable chip shape and reliable evacuation, this geometry reduces cycle times and supports higher productive feeds without compromising workpiece integrity.

Robust negative rake and rectangular form for heavy cuts

A 0° negative rake configuration increases the robustness of the cutting edge by distributing cutting forces across the insert body, which is beneficial for interrupted cuts, heavy radial engagement or unstable clamping conditions. The rectangular form delivers predictable seating in suitable toolholders and helps maintain alignment during index rotations, so less re‑adjustment is required. This construction is aimed at stable, repeatable performance in demanding milling tasks where edge stability is a priority.

Application guidance for stainless steel and superalloys

This indexable insert is particularly suitable for machining stainless steel and Group S alloys according to ISO classifications, where thermal resistance and edge security are paramount. Use the insert in tool assemblies and conditions that favour stable clamping and controlled cooling; the coated grade helps mitigate adhesion and heat‑related wear. For turning strategies that require chip segmentation, the F57T chipbreaker and rectangular shape support predictable results and simplified post‑process handling, improving overall process efficiency.

FAQ

What materials is this insert suited for?
The LNHU080404-F57T WSM35G insert from Walter Tools is designed primarily for stainless steel and heat‑resistant superalloys (ISO groups M and S), offering heat resistance and stable chip formation.

How does the F57T chipbreaker improve milling performance?
The F57T geometry produces segmented chips and promotes secure evacuation during milling; in combination with the WSM35G coating it reduces the risk of built‑up edge and supports consistent surface quality.

Can the rectangular form be used in standard milling holders?
Yes, the rectangular form of this indexable insert is compatible with suitable milling cutter bodies designed for rectangular inserts; correct toolholder seating ensures reliable indexing and repeatable results.

What is the benefit of the 0° negative rake for heavy operations?
A 0° negative rake increases edge robustness by distributing cutting forces more evenly, which is advantageous in interrupted cuts or heavy radial engagement and helps protect the cutting edge under severe conditions.
