LNHU100508-F57T WSP45G milling indexable insert – rectangle, 0° rake, Walter Tools

The LNHU100508-F57T WSP45G is a rectangular milling indexable insert designed for versatile face and shoulder milling of steel, stainless steel and heat-resistant superalloys in industrial production.

• Tiger·tec Gold PVD-coated carbide grade WSP45G
• Suitable for steel, stainless steel and superalloys
• Negative rake 0° for robust cutting
• Rectangle 10 format with 0.8 mm corner radius

High-performance grade for consistent chip control and edge life

The Tiger·tec Gold WSP45G grade combines a PVD coating with a tough substrate to deliver stable chip formation and improved resistance against abrasive wear. This results in more predictable tool behaviour during interrupted cuts and high-temperature cutting typical for stainless steel and nickel‑base alloys. The result is fewer unplanned tool changes and a more productive machining cycle. For planners and process engineers, the coated carbide’s balance between toughness and wear resistance supports longer tool life while maintaining dimensional stability on critical faces and shoulders.

Robust geometry that supports heavy and interrupted milling

The insert’s 0° negative rake and rectangular form provide a conservative cutting geometry that favours mechanical strength at the cutting edge. Combined with a 0.8 mm corner radius, this geometry reduces the risk of edge chipping during interrupted cuts and when machining difficult alloys. The integrated F57T chipbreaker is tuned to promote manageable chip shapes across a range of feeds, which simplifies evacuation and reduces heat concentration at the tool tip. Production managers will appreciate the reliability this brings to mix-and-match machining operations where varying workpiece materials are processed on the same machine.

Practical process benefits and application guidance

Intended for face and slot milling, the insert is compatible with steel (P), stainless steel (M) and high‑temperature alloys (S) as defined by ISO 513, so a single grade can cover multiple workpieces in a cell. The insert’s tolerance class H and the U execution contribute to consistent seating and repeatable clamping, which supports process stability and quality assurance. Where higher cutting speeds and improved surface finish are required, the Tiger·tec Gold technology helps maintain a stable cutting edge under thermal load, enabling tighter control of surface roughness without sacrificing tool life.

FAQ

What materials is this insert suitable for?
The LNHU100508-F57T WSP45G from Walter Tools is specified for steel (P), stainless steel (M) and heat‑resistant superalloys/titanium (S) according to the ISO groupings listed for the grade.

How does the 0° negative rake affect cutting performance?
A 0° negative rake gives the insert mechanical robustness and reduced tendency to chipping under interrupted cuts; the LNHU100508-F57T WSP45G benefits from this geometry when facing tough or abrasive workpieces.

What role does the F57T chipbreaker play?
The F57T chipbreaker promotes controlled chip breakage and evacuation across a range of feed rates, improving surface quality and lowering the risk of built‑up edge when using the WSP45G grade.
