LNHU080404-B57G WPP35G — Rectangular indexable milling insert, Tiger·tec Gold, for steel machining (0° negative rake) | Walter Tools

The LNHU080404-B57T WPP35G is a rectangular milling indexable insert designed for productive steel machining; it combines a coated cemented-carbide grade with a dedicated chipbreaker and compact corner radius for consistent surface finish and process reliability.

• Tiger·tec Gold coated for high productivity
• WPP35G grade for steel machining
• Rectangular insert with 0.4 mm corner radius
• Negative 0° rake for robust cutting

High-efficiency steel machining with Tiger·tec Gold

The insert uses the Tiger·tec Gold coating together with the WPP35G grade to deliver high cutting performance on ISO P (steel) materials. This combination reduces flank wear and improves tool life, resulting in fewer indexings and less downtime. The coated cemented-carbide substrate promotes consistent edge behaviour under the temperatures typical of steel machining, so cycle times can be shortened without sacrificing component quality. For production environments seeking measurable productivity gains, the coated grade supports stable chip formation and reliable repeatability.

Robust geometry for predictable results and surface quality

A dedicated chipbreaker B57T and a 0.4 mm corner radius provide a balance between strength and finishing capability: the chipbreaker controls curl and evacuation, reducing risk of built-up edge, while the compact radius helps to maintain dimensional accuracy and minimise vibration. The rectangular plate form and negative 0° free angle enhance insert clamping stability, making this solution suitable for heavier radial engagement and roughing passes where consistent cutting forces are required. These geometric choices translate into fewer rejects, steadier surface finish and improved process stability on steels.

Practical application guidance and process benefits

The insert is intended primarily for machining steel (ISO P). The design supports both roughing and mixed rough/finish operations when combined with appropriate cutting data. Choosing the WPP35G grade brings a balance between wear resistance and toughness, which is particularly useful when batches include varying heat treatment states. For production planning, the predictable wear behaviour and the optimized chip control reduce tool-change frequency and support lower overall machining costs. If cutting parameters need tuning for specific grades of steel, Metav Werkzeuge can provide tailored recommendations and trial data to integrate the insert into existing machining cycles.

FAQ

What materials is this insert suitable for?
The Walter Tools LNHU080404-B57T WPP35G is specified for ISO P materials, primarily unalloyed and alloyed steel, leveraging the WPP35G grade and Tiger·tec Gold coating for these applications.

How does the B57T chipbreaker affect machining?
The B57T chipbreaker on the LNHU080404-B57T promotes controlled chip formation and evacuation, improving surface finish and reducing the likelihood of built-up edge during steel machining.

Is the insert suitable for heavy roughing?
Yes. The rectangular plate form combined with a negative 0° free angle and robust corner radius provides stable clamping and cutting-edge support suitable for higher radial engagements.

What benefits does Tiger·tec Gold offer for production runs?
Tiger·tec Gold coating enhances wear resistance and thermal stability, so the WPP35G grade maintains edge condition over longer cycles, supporting consistent part quality and fewer tool changes.

Can Metav Werkzeuge provide cutting-data recommendations?
Metav Werkzeuge offers tailored cutting-data advice for integrating the LNHU080404-B57T WPP35G into specific machining processes and can advise on feeds and speeds for different steel grades.
