TNMG160408-FW5 WSM20S – Indexable turning insert, Tiger·tec Silver, Walter Tools (for stainless steel and superalloys)

A TNMG160408-FW5 WSM20S indexable turning insert engineered for demanding turning operations in stainless steel and heat‑resistant superalloys.

• Tiger·tec Silver coating for thermal stability
• WSM20S grade optimised for stainless steels
• Triangle 60° geometry with 0.8 mm corner radius
• Negative 0° rake for secure chip control

Consistent edge life for difficult materials

The Tiger·tec Silver coating and the WSM20S grade are formulated to maintain a stable cutting edge under the thermal and mechanical loads typical when machining stainless steel and superalloys. This results in longer tool life and fewer interruptions in the production flow, improving cost-efficiency per part. The combination of coating technology and substrate hardness supports a controlled wear pattern, reducing the risk of built-up edge and unexpected tool changes. The design therefore contributes to predictable cycle times and reliable surface finishes.

Precise geometry that improves process reliability

The triangular 60° geometry with a 0.8 mm corner radius and the negative 0° rake angle are configured to deliver secure engagement in turning applications, especially where robustness is required. The FW5 chipbreaker aids chip formation and evacuation, lowering the chance of entanglement and minimising rework. These geometric choices support a consistent cutting action, which makes the insert particularly suitable for interrupted cuts and tougher workpiece conditions. Result: increased machine uptime and repeatable part quality.

Clear application focus for machining specialists

Designed for machinability groups S and M according to ISO classification, this insert is targeted at work involving stainless steel and heat‑resistant superalloys, including titanium alloys depending on operation. The cutting grade excels where heat generation and adhesion tendencies would otherwise shorten tool life. For engineering teams seeking stable process windows and fewer tool interventions, the insert provides a pragmatic balance between wear resistance and edge stability, enabling productive turning without sacrificing surface integrity.

FAQ

What materials is this insert suitable for?
The TNMG160408-FW5 WSM20S insert from Walter Tools is suitable for stainless steel and for heat‑resistant superalloys (group S) and is optimised for demanding turning tasks.

How does the Tiger·tec Silver coating benefit the operation?
Tiger·tec Silver increases thermal resistance and supports a stable cutting edge on the WSM20S grade, which helps to reduce wear and maintain consistent performance in high‑temperature cutting of stainless steels.

What advantages does the Triangle 60° geometry provide?
The triangular 60° geometry with a 0.8 mm corner radius offers a robust cutting profile for finishing and semi‑finishing, while the FW5 chipbreaker improves chip control during interrupted and continuous cuts.

Is the negative 0° rake suitable for interrupted cuts?
Yes, the negative 0° rake of this insert enhances edge strength and contributes to secure chip control, making the insert well suited to interrupted or heavy engagement turning operations.

Can this insert be used on titanium alloys?
Depending on the machining parameters and insert geometry, the WSM20S grade can be employed on titanium and similar difficult‑to‑cut alloys, provided appropriate cutting data and coolant strategies are used.
