WNMG080404-FM5 WSM20S — Turning insert, Tiger-tec Silver, Trigon 80° (Walter Tools)

The WNMG080404-FM5 WSM20S is a triangular 80° coated carbide turning insert engineered for heavy-duty and finish turning of stainless steel and heat-resistant superalloys.

• Tiger·tec Silver coating for extended tool life
• Designed for stainless steel and superalloys
• FM5 chipbreaker for controlled chip formation
• Negative 0° rake for secure, stable cutting

Longer tool life through advanced coating and grade

The combination of the Tiger·tec Silver coating with the WSM20S grade provides a balance of thermal resistance and edge stability that benefits long uninterrupted cuts. The coated carbide composition means improved resistance to abrasive wear and thermal cracking compared with uncoated grades. For operations involving stainless steel or heat-resistant alloys, this results in fewer insert changes and more consistent component quality. The applied coating technology supports a reliable cutting edge under elevated temperatures, which in turn reduces the frequency of tool interventions and helps to keep production running smoothly.

Geometry that improves process stability and surface quality

The Trigon 80° form together with the FM5 chipbreaker and a 0.4 mm corner radius is tailored to combine rigidity and chip control. The negative 0° (negativ) rake angle increases edge strength for interrupted cuts and heavy cross-sections, while the chipbreaker promotes predictable chip breaking and evacuation. These attributes reduce vibrations and the risk of build-up on the cutting edge, which produces more repeatable surface finishes and lowers the need for manual rework. In practical terms, the geometry supports both secure roughing passes and controlled finishing, depending on the chosen cutting data.

Reliable productivity and clear application range

With tolerance class M and the specification aimed at groups S and M (titanium/superalloys and stainless steels), the insert suits machining tasks where heat and workpiece toughness place high demands on the tool. The FM5 chip control and the WSM20S coated carbide together contribute to predictable wear behaviour and extended effective life per insert, improving overall cost-efficiency in production. The insert's design permits consistent tool performance on CNC lathes and turning centres, supporting stable process windows and reducing unplanned downtime. For customers seeking process security and repeatability, this insert offers a robust option within the Tiger·tec Silver family.

FAQ

What materials is this insert suitable for?
The WNMG080404-FM5 WSM20S turning insert (Walter Tools) is specified for stainless steel and for heat-resistant superalloys/titanium as indicated by its S / M suitability.

How does the Tiger·tec Silver coating affect tool life?
The Tiger·tec Silver coating on the WSM20S grade enhances thermal and abrasive resistance, improving edge life and enabling longer uninterrupted cutting periods in demanding turning tasks.

What is the advantage of the FM5 chipbreaker?
The FM5 chipbreaker is designed to promote consistent chip formation and evacuation, which reduces build-up and helps to maintain a stable cutting edge for improved surface quality.

Can this insert handle interrupted cuts?
Yes, the negative 0° rake and the robust Trigon 80° geometry of the WNMG080404-FM5 insert provide increased edge strength suitable for interrupted and heavy turning operations.

What does tolerance class M indicate for this insert?
Tolerance class M denotes the manufacturing precision of the insert; in practice it supports consistent seating and repeatable performance in tool holders and turning applications.
