LNMU080404-F57T WSP45G milling indexable insert by Walter Tools — Tiger·tec Gold PVD, rectangular 0.4 mm radius

The LNMU080404-F57T WSP45G is a rectangular milling indexable insert designed for versatile face and shoulder milling in a wide range of alloys, offering stable cutting performance in demanding operations.

Tiger·tec Gold PVD coating for long tool life
Suitable for steel, stainless steel and superalloys
Rectangular insert with 0.4 mm corner radius
Negative rake 0° for stable cutting edge

High process security from advanced coating and grade

The insert is built on the Tiger·tec Gold platform and uses the WSP45G coated-carbide grade, which combines a hard PVD coating with a tough substrate to resist wear while avoiding brittle fracture. This composition supports secure chip formation when machining common structural steels and steels with higher toughness. The result is consistent tool life and predictable change intervals, which aids production planning and reduces unplanned downtime.

Optimised geometry for reliable milling results

The rectangular form with a 0.4 mm corner radius and the specified chipbreaker F57T provide a balance between edge strength and controlled chip flow. The negative rake configuration (0°) improves cutting-edge stability under intermittent cuts and heavy engagement, reducing the tendency for built-up edge on stainless materials. These geometric choices translate into fewer reworks and higher first-pass yield on challenging components.

Broad application range across demanding materials

Designed for the material groups P, M and S, the grade is suitable for unalloyed and alloyed steel, stainless steel and heat-resistant superalloys or titanium. The insert’s toughness supports the thermal and mechanical loads typical of these groups, while the coating limits flank and crater wear. For manufacturers processing mixed batches or diverse components, this insert reduces tool change complexity and simplifies inventory management.

Practical properties for workshop integration

With an insert size designation of 08 and a thickness code of 04, the part follows common indexing standards for easy replacement in compatible toolholders. The tolerance class M ensures repeatable seating and stable clamping; this contributes directly to dimensional consistency across runs. Together, size, tolerance and coating deliver a practical solution for shops seeking a versatile, durable milling insert from a recognised brand.

FAQ

What materials is this insert suitable for?
The WSP45G grade is designed for machining steel, stainless steel and heat-resistant superalloys/titanium, covering ISO groups P, M and S.

How does the Tiger·tec Gold coating benefit machining?
The Tiger·tec Gold PVD coating on the insert reduces wear and improves thermal resistance, resulting in longer tool life and stable cutting performance under high load.

What does the chipbreaker F57T provide?
The F57T chipbreaker controls chip geometry and evacuation for milling operations, which supports consistent surface finishes and reduces risk of chip re-cutting.

Is the insert compatible with standard toolholders?
The insert follows common indexable plate dimensions (size 08, thickness 04) and tolerance class M, allowing compatibility with matching Walter Tools and other standard toolholders that accept this ISO form.

What advantage does the negative rake angle offer?
A negative rake (0°) increases edge strength and resistance to impact, improving stability in interrupted cuts and when machining tougher materials.
