LNMU130608R-L55T WSP45G milling indexable insert by Walter Tools — Tiger·tec Gold, rectangle 0.8 mm corner radius

LNMU130608R-L55T WSP45G is a coated carbide milling insert designed for versatile milling tasks in steel, stainless steel and superalloys, offering robust edge integrity for demanding production environments.

• Tiger·tec Gold PVD-coated grade WSP45G
• For steel, stainless steel and superalloys
• Stable cutting edge for demanding milling
• Rectangle form with 0.8 mm corner radius

Coating and grade that sustain productivity

The Tiger·tec Gold technology and WSP45G grade deliver a PVD-coated surface engineered for wear resistance and consistent performance. This coating reduces flank and crater wear, enabling longer periods between index changes and thus higher effective machining time. For industrial milling applications the combination of a tough substrate and PVD layers supports reliable chip formation across the P, M and S ISO material groups, translating directly into improved process stability and fewer unplanned tool changes.

Geometry tuned for edge security and surface quality

The rectangular geometry with a 0.8 mm corner radius and the L55T chipbreaker are configured to promote stable cutting conditions in interrupted and continuous milling. A modest corner radius strengthens the cutting edge against mechanical and thermal loads, reducing the risk of chipping when machining challenging alloys. The negative 0° relief (negative rake) enhances edge robustness under heavy engagement, which helps maintain repeatable surface finishes and predictable tool life in series production.

Application scope and machining behaviour

Engineered for a wide range of workpieces, this insert is suitable for unalloyed and alloyed steel, austenitic and other stainless steel grades, and heat-resistant superalloys and titanium. The grade is formulated to balance toughness and wear resistance so that chip control and edge life remain dependable even under higher temperatures typical when machining S group materials. The design supports secure chip evacuation and reduces built-up edge tendencies, which is especially relevant when removing material at moderate to heavy depths of cut.

Production benefits and cost-efficient handling

As an indexable solution, the insert reduces downtime by allowing quick replacement without regrinding a solid tool body. The combination of a robust cutting edge and the WSP45G coating results in predictable tool-change intervals and simplified inventory planning. In mixed-production environments the insert’s versatility lowers the number of different tool grades required, contributing to lower tooling overhead and a streamlined tool management process in the workshop.
