WNMG080408-MM5 WMP20S Trigon 80° indexable turning insert for rostfreier Stahl — Walter Tools

The WNMG080408-MM5 WMP20S is a trigon 80° indexable turning insert engineered for medium to robust turning of rostfreier Stahl components in demanding production environments.

• Tiger·tec Silver coating technology
• MM5 chipbreaker for stable chip control
• Trigon 80° geometry for robust cutting
• 0° (negative) free angle for heavy cuts

Proven process security through coating and chip control

The combination of the Tiger·tec Silver coating and the WMP20S grade provides a durable, heat-resistant surface that stabilises the cutting edge under elevated temperatures typical for rostfreier Stahl machining. The coated carbide technology reduces adhesion and protects the substrate, which results in fewer interruptions for edge maintenance and a more predictable lifetime. The MM5 chipbreaker is designed to produce consistent, controllable chips, lowering the risk of built-up edge and improving surface finish in continuous and interrupted cuts.

Geometry and edge form that support robust turning

A Trigon 80° shape with an 0° (negative) free angle makes the insert ideal for heavier cuts and interrupted cutting conditions where rigidity and cutting stability are priorities. The relatively large 0.8 mm corner radius distributes cutting forces across a broader edge, increasing resistance to edge chipping and contributing to longer tool life under medium to robust cutting regimes. These geometric choices favour manufacturers seeking reliable, repeatable results when processing rostfreier Stahl.

Practical integration into production workflows

The insert’s standard designation and compatibility simplify tooling inventory and setup: the ISO-style designation aligns with common toolholders and the compact plate size facilitates fast indexing and replacement. Because the grade is aimed at rostfreier Stahl applications, process engineers can expect improved repeatability and fewer rejects when the cutting data is adapted to the material’s heat generation and tendency to work-harden. For customers less familiar with chipbreaker selection or feed/speed optimisation, the technical guidance available from Metav Werkzeuge helps to translate geometry and coating advantages into measurable productivity gains.

FAQ

What materials is this insert suitable for?
The WNMG080408-MM5 WMP20S is designed primarily for rostfreier Stahl; the grade and coating support chip control and edge stability under the higher heat and work-hardening tendencies of these materials.

What does the Tiger·tec Silver coating provide?
Tiger·tec Silver is a multi-layer coating technology that enhances thermal resistance and reduces adhesion, allowing the Walter Tools grade WMP20S to maintain a stable cutting edge for longer and improve process repeatability.

How does the MM5 chipbreaker influence performance?
The MM5 chipbreaker promotes consistent chip formation and evacuation, which reduces the likelihood of built-up edge and supports a better surface finish when turning rostfreier Stahl with the WNMG080408-MM5 insert.

When is a 0° (negative) free angle advantageous?
A 0° (negative) free angle is beneficial for heavier cuts and interrupted machining where a stronger cutting edge and increased radial support are required to avoid chipping and ensure stable cutting forces.

Is the Trigon 80° shape universal for all turning operations?
The Trigon 80° form is particularly effective for medium to robust turning tasks and offers flexibility in a variety of external and face-turning operations; decisions on holder selection and feeds should be made based on the specific application.
