SNMG120404‑FM5 WSM20S turning insert — Tiger·tec Silver grade for stainless steel and superalloys (Walter Tools)

SNMG120404‑FM5 WSM20S is a square turning insert designed for demanding roughing and finishing operations in stainless steel and heat‑resistant superalloys

• Tiger·tec Silver coating for high temperature stability
• WSM20S grade for stainless steel and superalloys
• FM5 chipbreaker for reliable chip control
• Square 90° form with 0.4 mm corner radius

Increased cutting security for hard‑to‑machine alloys

The SNMG120404‑FM5 WSM20S insert combines a proven Tiger·tec Silver coating with the WSM20S carbide grade to deliver stable cutting performance where heat and adhesion are critical. This combination reduces the tendency for built‑up edge when machining stainless steel, supporting a robust and predictable cutting process. The result is fewer interrupted cycles and more consistent component quality, which benefits process planners who prioritise uptime and reproducibility.

Controlled chip formation and reduced rework

Equipped with the FM5 chipbreaker geometry and a 0.4 mm corner radius, this square insert is engineered for dependable chip control across varying depths of cut. Effective chip shaping lowers the risk of surface damage and makes chip evacuation more reliable, particularly in long or interrupted cuts. For production teams, this translates into lower scrap rates and reduced manual rework, improving overall throughput without sacrificing surface integrity.

Geometry tailored to versatile turning tasks

The square 90° plate form and a negative 0° relief angle provide a sturdy cutting edge and enhanced edge strength during heavy interrupted cuts. The insert thickness and form support secure clamping and repeatable tool setting, making it suitable for both roughing passes and semi‑finishing operations. Clear geometry choices simplify tool selection and make it easier to standardise tooling across similar stainless steel applications.

Practical benefits for shops and OEMs

Using a coated grade engineered for high thermal loads means longer effective tool life and fewer insert changes per part lot. The WSM20S grade is matched to the demands of stainless steel and heat‑resistant alloys, helping to maintain dimensional accuracy over longer runs. This focused material compatibility aids purchasing decisions by reducing the need for an extensive variety of grades while ensuring consistent performance where it matters most.

FAQ

What materials is this insert suited for?
The SNMG120404‑FM5 WSM20S insert is specified for stainless steel (M) and heat‑resistant superalloys or titanium (S), reflecting the WSM20S grade’s focus on thermal stability and edge integrity.

How does the FM5 chipbreaker affect machining?
The FM5 chipbreaker is designed to create manageable chips and steady cutting forces, which improves surface finish and reduces the chance of chip interference during turning operations with the SNMG120404‑FM5 insert.

Is the Tiger·tec Silver coating beneficial for long runs?
Yes. The Tiger·tec Silver coating provides enhanced resistance to thermal loads and adhesion, extending tool life and supporting consistent performance over extended cycle times when machining stainless steel.

What does the 0.4 corner radius mean for cutting?
A 0.4 mm corner radius balances edge strength and finish capability; it supports robust cutting during heavier passes while still allowing acceptable surface quality for many finishing operations.

Can the insert be used for interrupted cuts?
The square form and negative relief combined with the robust grade make this insert suitable for interrupted cuts, offering improved edge stability compared with finer, less robust geometries.
