LNHU090420R-L55G WSP45G — Milling insert for Stahl, rostfreier Stahl and superalloys (Walter Tools)

The LNHU090420R-L55T WSP45G is a rectangular milling insert designed for secure chip control and long tool life in a broad range of milling operations, suitable for Stahl, rostfreier Stahl and high-temperature alloys.

• Tiger·tec Gold coating for extended tool life
• WSP45G grade for P / M / S materials
• 0° negative rake for robust milling
• L55T chipbreaker for controlled chips

High-performance coating and material adaptability for efficient machining

The combination of the Tiger·tec Gold coating and the WSP45G carbide grade delivers a reliable balance between wear resistance and edge stability. This engineered coating system supports stable cutting when machining Stahl, rostfreier Stahl and demanding heat-resistant alloys, reducing the frequency of tool changes and helping to sustain cycle times. The result is an insert that keeps machining economical under variable process loads while providing consistent surface quality.

Controlled chip formation and mechanical robustness for stable production

The rectangular geometry with the integrated L55T chipbreaker governs chip shape and evacuation, especially in interrupted or trochoidal milling strategies. A 0° negative rake increases mechanical strength at the cutting edge, which is advantageous when higher feed rates or heavier cuts are required. The corner radius 2 contributes to edge toughness and improved tool life in roughing passes, while the design still supports acceptable finishing performance when machining components that demand repeatable accuracy.

Application guidance and process integration for reliable results

As a versatile indexable solution, the insert suits a wide range of milling tasks from slotting and shoulder milling to more demanding side-milling in nickel‑base or titanium alloys. The designation reflects its form and chipcontrol characteristics, making process planning and tool selection straightforward in production environments. For process optimisation, pairing the insert with a suitably rigid cutter body and adapting cutting parameters to the workpiece group (P / M / S) will yield predictable tool wear and part quality.

FAQ

Which materials can be machined with this insert?
The insert is suitable for Stahl (P), rostfreier Stahl (M) and heat‑resistant superalloys/titanium (S) thanks to the WSP45G grade and Tiger·tec Gold coating.

What does the designation LNHU090420R-L55T indicate?
The designation specifies form and functional details: rectangular form, size code 09, thickness 04, corner radius 2 and chipbreaker L55T, as used in the Walter Tools milling programme.

How does the L55T chipbreaker influence machining?
The L55T chipbreaker promotes controlled chip formation in milling, improving evacuation and reducing the risk of built-up edge under varying cutting conditions.

Is the negative 0° relief angle a disadvantage for finishing operations?
A 0° negative rake increases edge strength for heavy cutting; finishing can still be achieved by optimising feeds and speeds or by using the insert with smaller radial engagement where surface finish is critical.

What installation considerations are important for this rectangular insert?
Ensure a compatible, rigid cutter body and correct seat geometry for the rectangular shape; secure clamping and appropriate parameter selection for the workpiece group (P / M / S) will support consistent performance.
