SCMT09T304-FM4 WSM20S – indexable turning insert (Tiger·tec Silver, FM4) by Walter Tools

A robust SCMT09T304-FM4 WSM20S indexable turning insert engineered for secure chip formation and edge stability during the machining of rostfreier Stahl and high‑temperature alloys.

• Tiger·tec Silver coating for edge stability
• Suitable for rostfreier Stahl and superalloys
• FM4 chipbreaker for secure chip control
• Square 90° geometry with 0.4 mm corner radius

Consistent performance where heat and toughness challenge process stability

The combination of Tiger·tec Silver coating and the WSM20S grade targets applications with elevated temperatures and adhesive tendencies, notably rostfreier Stahl and nickel‑based alloys. The coating enhances thermal resistance and reduces flank wear, which translates into longer tool life and fewer interruptions for index changes. For production environments where cycle time and component surface quality are measured, this insert supports a predictable tool change interval and a stable cutting process.

Chip control and surface quality that support reliable throughput

Equipped with an FM4 chipbreaker and a 0.4 mm corner radius, the insert promotes controllable chip formation even under unfavourable cutting conditions. Controlled chips minimise machine downtime and ease chip evacuation in automatic systems, while the square 90° geometry contributes to robust axial engagement and consistent part geometry. Together these features improve first‑pass yields and reduce the need for secondary finishing on sensitive parts.

Practical selection and machining guidance for workshop integration

The insert's specification—short relief angle 7°, thickness T3 and tolerance class M—makes it suitable for turning operations where edge strength and stable geometry are priorities. In practice, select cutting parameters that balance speed and feed to exploit the grade’s thermal properties: modest increases in feed can often improve chip breaking without compromising surface finish. For assistance tuning parameters to specific machines or material batches, Metav Werkzeuge consultants provide application support and cutting‑data recommendations.

FAQ

What materials is this insert suitable for?
The SCMT09T304-FM4 WSM20S indexable turning insert from Walter Tools is designed for rostfreier Stahl and heat‑resistant superalloys (ISO groups M and S), providing improved thermal resistance and edge stability.

How does the FM4 chipbreaker affect machining?
The FM4 chipbreaker on the Walter Tools insert shapes chips for secure evacuation and reduced entanglement, which supports continuous operation and simplifies handling in automated turning processes.

What benefits does the Tiger·tec Silver coating provide?
Tiger·tec Silver increases thermal stability and wear resistance for the WSM20S grade, helping to maintain a stable cutting edge and extend index intervals under demanding conditions.

Is the 0.4 mm corner radius suitable for finishing?
A 0.4 mm corner radius offers a compromise between edge strength and surface finish; it helps to avoid premature edge failure while still allowing for good workpiece quality in medium‑ to finishing cuts.

Can this insert be used interchangeably in standard toolholders?
The insert conforms to the SCMT geometry and can be mounted in compatible toolholders designed for 09‑size, square 90° inserts; verify holder compatibility before assembly.
