LNHU080304-B57G WPP35G — Milling indexable insert, 0° negative rake, 0.4 mm radius, Walter Tools

The LNHU080304-B57T WPP35G is a rectangular milling indexable insert engineered for high-performance steel machining, combining Tiger‑tec Gold coating with a B57T chipbreaker for stable chip formation.

• Tiger‑tec Gold coating for long tool life
• Optimised for steel machining (ISO P)
• 0° negative rake for robust cutting
• 0.4 mm corner radius for precise edge strength

Increase productivity with an advanced coating technology

The use of Tiger‑tec Gold in this cutting grade provides a measurable advantage in machining cycles by enhancing thermal resistance and wear protection. This results in longer tool life and fewer indexings per production batch, which lowers downtime and reduces tooling costs. The coated insert tolerates elevated cutting speeds typical in steel production and helps maintain consistent surface quality over extended runs. Evidence-based selection of coating technology supports predictable tool performance and process stability.

Consistent chip control tailored for steels

Designed for the ISO P material class, the WPP35G grade and B57T chipbreaker focus on reliable chip formation when machining steel, including unalloyed and alloyed variants. Stable chip flow reduces the risk of built-up edge and improves machinability in both semi-finishing and finishing passes. This characteristic contributes to repeatable part quality and simplifies downstream handling, helping to avoid rework and maintain throughput in serial production environments.

Geometry that supports dependable machining results

The rectangular plate form, combined with a 0° negative rake angle and a 0.4 mm corner radius, provides a sturdy cutting edge that resists mechanical shock and edge chipping. This geometry is particularly useful in interrupted cuts and heavy engagement milling where edge strength is essential. The plate thickness and dimensional tolerance class H promote secure clamping and positional repeatability in toolholders, which together ensure consistent cutting behaviour and predictable tool life per index.

Easy integration and predictable process behaviour

Marked as LNHU080304-B57T and produced by Walter Tools, the insert fits typical compatible milling bodies and is straightforward to index and replace. The combination of clear designation, stable coating and chip control simplifies tooling selection for production planners and reduces setup time at the machine. For operations seeking to balance productivity with operational reliability, this grade offers a pragmatic choice that aligns with modern machining strategies and lean process demands.
