LNHU160712R-L55T WSP45G milling insert – Tiger·tec Gold, negative 0° (Walter Tools)

The LNHU160712R-L55T WSP45G is a rectangular milling indexable insert designed for versatile face and peripheral milling across steel, stainless steel and superalloys, delivering reliable PVD-coated performance in mixed-production environments

• Tiger·tec Gold PVD coating for high durability
• Designed for steel, stainless steel and superalloys
• Negative 0° rake with 1.2 mm corner radius
• Rectangular insert with L55T chipbreaker

Optimised performance for high-productivity milling

The insert is supplied in the Tiger·tec Gold family and the WSP45G grade, a PVD-coated cemented carbide developed for robust milling. This composition prioritises edge stability and repeatable wear behaviour, which translates into longer intervals between index changes and fewer unplanned tool changes. For production environments with mixed batches, the combination of coating technology and substrate hardness reduces the risk of premature flank wear and supports stable cutting forces, thereby helping to maintain consistent component dimensions and surface finish throughout longer tool cycles.

Predictable cutting behaviour and secure edge life

The negative 0° rake geometry and the 1.2 mm corner radius deliver a secure cutting action that favours controlled chip formation under variable cutting conditions. The integrated L55T chipbreaker promotes short, manageable chips during interrupted cuts and slotting, lowering the chance of re-cutting and tool damage. As a result, machining cycles benefit from enhanced process reliability and fewer interruptions, which improves throughput and supports leaner production planning with predictable tool replacement intervals.

Broad material capability with clear application guidance

This grade is specified for the ISO material groups P / M / S, meaning suitability for unalloyed and alloyed steel, stainless steel and heat-resistant superalloys or titanium. The WSP45G chemistry is tuned to handle the typical heat generation and work-hardening tendencies of these materials while maintaining a stable cutting edge. In practice, this makes the insert suitable for a range of operations from robust roughing passes to medium-finishing, especially where a single insert stock is preferred to reduce tool inventory and changeover time.

Production-ready design and handling benefits

The rectangular form factor and the thickness code support secure clamping and simple indexing, while the tolerance class H ensures repeatable seating in standard toolholders. As a component of the Tiger·tec Gold series, the insert aligns with Walter Tools’ emphasis on process security and consistent surface quality. For workshops aiming to streamline tool management, the robust combination of geometry and coating contributes to fewer stoppages, stable cycle times and ultimately improved overall equipment effectiveness.

FAQ

What materials is the insert suitable for?
The LNHU160712R-L55T WSP45G insert is specified for ISO groups P, M and S, covering steel, stainless steel and high-temperature alloys or titanium.

How does the Tiger·tec Gold grade affect tool life?
The Tiger·tec Gold coating on the WSP45G grade enhances wear resistance and heat management, delivering more predictable tool life and consistent cutting performance in milling operations.

Which machining tasks benefit most from the L55T chipbreaker?
Operations with interrupted cuts, pocketing and general roughing to medium finishing gain from the L55T chipbreaker, which creates short, controlled chips and reduces re-cutting.

Is the negative 0° rake suitable for heavy cuts?
Yes, the negative 0° rake provides a robust cutting edge and is suited to higher radial loads and roughing passes where stability and edge protection are priorities.

What does the thickness code 07 mean for clamping?
The thickness code indicates the insert profile used in standard indexable holders; correct seating and the H tolerance class support repeatable mounting and secure clamping.
