LNGX130712R-L55 WSP45G rectangular milling insert, Tiger·tec Gold, Walter Tools

LNGX130712R-L55 WSP45G is a rectangular indexable milling insert designed for versatile milling in steel, stainless steel and heat-resistant alloys

• Tiger·tec Gold PVD coating for long life
• Suitable for steel, stainless steel and superalloys
• Negative 0° rake for stable cutting
• Rectangular insert with 1.2 mm corner radius

High-performance coating for longer tool life

The insert’s Tiger·tec Gold coating combined with the WSP45G grade provides a balance of wear resistance and toughness that is optimised for milling operations. This PVD-coated carbide formulation reduces flank wear and supports a stable cutting edge under cyclic thermal loading, which in turn extends tool life and reduces downtime. For process planners this means fewer tool changes and a more predictable maintenance schedule, contributing directly to productive machining cycles and improved overall equipment effectiveness.

Stable chip control and consistent surface finish

The L55 chipbreaker and the negative 0° rake were developed to promote secure chip formation and evacuation during face and peripheral milling. Together they produce short, controllable chips that reduce the risk of re-cutting and minimise surface damage. The result is a consistent surface finish and reduced secondary operations. This characteristic is particularly valuable in series production where cycle-time reduction and repeatability are decisive for cost-efficiency and quality assurance.

Versatile application across demanding materials

Engineered for the ISO groups P / M / S, the insert performs well on unalloyed and alloyed steel, stainless steel and heat-resistant superalloys or titanium-based materials. The grade’s toughness supports machining of materials that generate built-up edge or high temperatures, while the coating protects the cutting edge from abrasive wear. For manufacturers working with mixed-batch production, this versatility reduces the need for multiple specialised grades and simplifies tool inventory management.

Design details that support secure clamping and accuracy

The rectangular geometry (size 13) with a 1.2 mm corner radius offers a reliable cutting edge for both heavy and finishing passes, while the 07 plate thickness code and G tolerance class ensure consistent seating and repeatable tool-to-tool accuracy. The insert is supplied in the LNGX130712R-L55 designation and matches standard Walter Tools milling cutter bodies for quick index changes. These design choices help to reduce set-up time and support stable machining processes in both job-shop and production environments.

FAQ

What materials is this insert suitable for?
The LNGX130712R-L55 WSP45G insert is suitable for ISO groups P, M and S, meaning it can be used for machining steel, stainless steel and heat-resistant superalloys or titanium.

How does the Tiger·tec Gold coating benefit machining?
The Tiger·tec Gold coating on this Walter Tools insert increases wear resistance and temperature stability, which helps to extend tool life and maintain a consistent cutting edge over longer production runs.

Is the insert intended for heavy roughing or finishing?
With its rectangular shape and 1.2 mm corner radius, the insert suits both heavy passes and finishing work; the L55 chipbreaker promotes controlled chips across a range of cutting conditions.

Can this insert be used in standard Walter milling cutters?
Yes, the LNGX130712R-L55 designation corresponds to standard Walter Tools cutter bodies designed for quick indexable insert changes and secure clamping.

What does the negative 0° free angle mean in practice?
A negative 0° free angle gives a neutral rake geometry that improves edge stability under high cutting forces, which is beneficial when machining tougher materials or when increased robustness is required.
