LNHU090416R-L55G milling indexable insert — Tiger·tec Gold, for steel, stainless and superalloys (Walter Tools)

A LNHU090416R-L55T WSP45G milling insert engineered for versatile milling operations in steel, stainless steel and heat-resistant superalloys, offering high process security and consistent results

• Tiger·tec Gold PVD-coated carbide
• WSP45G grade for P / M / S materials
• Negative rake 0° for edge stability
• Corner radius 1.6 mm, rectangular form

Consistent machining performance and longer tool life

The combination of the Tiger·tec Gold coating and the WSP45G grade provides a PVD-coated carbide formulation optimised for toughness and thermal resistance. This composition improves chip formation and supports a stable cutting edge under the thermal loads typical of milling steels and stainless steels, as well as heat-resistant superalloys. The integrated chipbreaker L55T promotes predictable chips, reducing the risk of built-up edge and interruptions in the production flow; the result is fewer tool changes and improved overall productivity. For shops aiming to raise process efficiency, these material and coating choices translate directly into measurable operational benefits.

Robust geometry that secures cutting conditions

A neutral, negative rake 0° strengthens the cutting edge and enhances resistance to edge chipping during interrupted or heavy engagement cuts. The rectangular plate geometry combined with a corner radius of 1.6 mm provides a solid contact area and distributes cutting forces evenly, improving stability in roughing and semi-finishing passes. The tolerance class H ensures consistent seating and repeatable positioning in the toolholder, which is essential for reproducible part quality and minimal set-up variation. Operators and planners gain predictable behaviour from the tooling, which supports tighter process control and reduced scrap rates.

Wide applicability and straightforward integration into production

Designed for a broad material spectrum — steel, stainless steel and superalloys/titanium — this insert offers versatility for mixed-production environments. The PVD coating enhances surface finish and wear resistance without compromising the substrate toughness, so reliable performance is maintained across varying cutting conditions. As part of the Tiger·tec Gold series, the insert supports stable machining where both thermal load and adhesion risks are present. For application selection and parameter tuning, technical advisers at Metav Werkzeuge can provide guidance on speeds, feeds and toolholder choices to integrate the insert into existing machining strategies with minimal downtime.

FAQ

Which materials are suitable for this insert? The LNHU090416R-L55T WSP45G insert is specified for machining steel (P), stainless steel (M) and heat-resistant superalloys/titanium (S), reflecting the versatility of the Tiger·tec Gold grade.

What coating and grade does the insert use? This milling insert uses the Tiger·tec Gold PVD coating and the WSP45G grade, a PVD-coated carbide formulation optimised for toughness and thermal stability.

What is the corner radius and why does it matter? The corner radius is 1.6 mm; this radius increases edge strength and contributes to stable cutting conditions, especially under interrupted or high-load milling operations.

Is the insert suitable for interrupted cuts or heavy engagement? Yes. The negative rake 0° geometry reinforces the cutting edge and, together with the rectangular shape, supports robust performance during interrupted cuts and heavy material removal.

How does the tolerance class affect tooling performance? Tolerance class H ensures repeatable seating in the toolholder, which improves positional accuracy and contributes to consistent surface quality and process reliability when using this Walter Tools milling insert.
