WNMG080412‑MU5 WMP20S indexable turning insert — Trigon 80°, for rostfreier Stahl — Walter Tools

WNMG080412‑MU5 WMP20S is an indexable turning insert engineered for medium to robust turning of rostfreier Stahl in commercial and industrial production environments, providing stable cutting edges and predictable chip formation.

• Tiger·tec Silver coating for stable edges
• Optimised for rostfreier Stahl machining
• Trigon 80° geometry for secure engagement
• MU5 chipbreaker for controlled chip formation

Longer tool life and consistent edge performance

The WNMG080412‑MU5 WMP20S insert combines a coated cemented carbide grade with the Tiger·tec Silver coating technology to deliver improved resistance to wear and thermal loading in rostfreier Stahl applications. The MU5 chipbreaker is designed to support stable chip segmentation, reducing the risk of built‑up edge and facilitating evacuation in interrupted or continuous cuts. This results in fewer tool changes and more reliable cycle times, which supports cost‑efficient production and predictable maintenance intervals.

Confident machining of rostfreier Stahl with controlled forces

Rostfreier Stahl tends to produce tough, adhesive chips and generates high temperatures at the cutting zone. The 0° negative rake and the Trigon 80° insert shape create a stiff cutting geometry that reduces deflection and keeps cutting forces stable during turning operations. The 1.2 mm corner radius provides a robust cutting edge that tolerates moderate variances in feed and depth of cut, improving repeatability on batch work and complex stainless components. For workshops seeking process stability, this combination reduces scrap rates and improves surface consistency.

Practical integration into production for higher throughput

The compact form and standard WNMG designation mean straightforward implementation in common toolholders and turning systems; the insert’s iso code and grade simplify tool management across machines. The hardened, coated substrate and optimised chip control permit higher metal removal rates compared with uncoated grades under comparable conditions, supporting faster cycle times where appropriate. For selection of cutting parameters or when transitioning from a different grade, Metav Werkzeuge provides technical advice and application guidance to align the WMP20S performance with specific rostfreier Stahl alloys and machining setups.

FAQ

What materials is this insert intended for?
The WNMG080412‑MU5 WMP20S insert is specified for machining rostfreier Stahl and is tuned for the tougher, adhesive behaviour typical of those alloys.

How does the MU5 chipbreaker benefit production?
The MU5 chipbreaker promotes controlled chip segmentation and evacuation, reducing built‑up edge and aiding consistent cycle times when using the WMP20S grade.

What does the Trigon 80° shape mean for tool setup?
The Trigon 80° geometry provides a secure insert seating with a compact cutting profile, improving rigidity and repeatable positioning in standard turning toolholders.

Is the WMP20S grade suitable for finishing passes?
Yes—WMP20S offers a balance of wear resistance and edge stability appropriate for finishing and medium stock removal on rostfreier Stahl, depending on selected feeds and speeds.

Which features reduce downtime in series production?
The combination of Tiger·tec Silver coating, a robust 1.2 mm corner radius and the MU5 chipbreaker reduces edge chipping and tool changes, supporting longer uninterrupted production runs.
