LNHU090404R-L55T WSP45G rectangular milling insert by Walter Tools — Tiger·tec Gold PVD, chipbreaker L55T

LNHU090404R-L55G WSP45G is a PVD-coated, rectangular milling insert designed for productive milling of steel, stainless steel and heat-resistant alloys

• Tiger·tec Gold coating for extended life
• Suitable for steel, stainless and superalloys
• Negative 0° relief for stable cutting
• Rectangular shape with 0.4 mm corner radius

Reliable wear resistance for productive milling

The combination of the Tiger·tec Gold coating and the WSP45G grade produces a PVD-coated carbide body that is optimised for the thermal and mechanical loads typical of milling steel, stainless steel and superalloys. The coating reduces flank wear and enhances resistance to built-up edge, which translates into longer tool life and fewer indexings. For production environments this means more predictable tool-change intervals and improved part-to-part consistency. The technical advantage of a coated grade is that it supports secure chip formation under variable cutting conditions and contributes directly to lower unit costs in series machining.

Geometry engineered for cutting stability and edge strength

The rectangular plate form with a negative 0° relief provides a mechanically strong cutting edge that tolerates interruptions and heavy engagement without premature chipping. The 0.4 mm corner radius increases edge strength for robust profile milling and shoulder operations, while the L55T chipbreaker supports controlled chip flow, reducing the risk of clogging in slotting or higher-feed passes. Negative relief geometry also improves vibration damping and makes the insert suitable for higher-depth cuts where stability is critical. These design choices ensure a balance between reliable edge life and the capacity for demanding material removal.

Process reliability, suitability and application guidance

Classified in tolerance H and delivered within the Tiger·tec Gold series, this insert is intended for versatile milling duties across ISO groups P, M and S (steel, stainless steel and heat-resistant alloys). The WSP45G grade favours secure chip control and stable cutting edges during continuous and interrupted cuts. In practice, the insert benefits job shops and production lines requiring repeatable surface quality and machining economy; lower downtime and predictable wear behaviour enhance overall productivity. For specifics on cutting data and adaptation to a given machine or workpiece material, the Metav Werkzeuge technical team can provide application-oriented guidance and cutting-parameter recommendations.

FAQ

What materials is this insert suitable for?
The LNHU090404R-L55T WSP45G insert is specified for ISO groups P, M and S, making it suitable for steel, stainless steel and heat‑resistant superalloys in milling applications.

How does the Tiger·tec Gold coating benefit tool life?
The Tiger·tec Gold PVD coating on the WSP45G grade reduces flank wear and supports stable chip formation, which extends insert life and improves process stability in series milling.

Why choose a negative 0° relief insert for milling?
A negative 0° relief increases edge robustness and resistance to chipping during interrupted cuts; this geometry supports higher engagement and improved vibration damping for consistent surface quality.

What role does the L55T chipbreaker play?
The L55T chipbreaker promotes controlled chip breaking and evacuation, lowering the risk of chip congestion in slotting and improving heat management at the cutting zone.

Is this insert appropriate for heavy-duty shoulder milling?
Yes; the rectangular form combined with a 0.4 mm corner radius and the WSP45G grade provides the edge strength required for heavier passes and shoulder milling with enhanced reliability.
