CNMG120404-FM5 WSM10S indexable turning insert, Tiger‑tec Silver — for stainless steels and heat‑resistant superalloys | Walter Tools

The CNMG120404-FM5 WSM10S is a rhombic 80° indexable turning insert engineered for secure chip formation and reliable performance when machining stainless steels and heat‑resistant superalloys.

• Tiger‑tec Silver coated carbide grade WSM10S
• Rhombic 80° geometry, 0.4 mm corner radius
• FM5 chipbreaker for secure chip control
• Negative rake 0° for heavy interrupted machining

Consistent machining of hard‑to‑cut alloys for improved throughput

The coated carbide WSM10S grade from the Tiger‑tec Silver family is formulated to support machining of stainless steels and heat‑resistant superalloys with improved edge stability. This composition reduces the tendency for built‑up edge and helps maintain cutting performance over longer tool life. As a result, shorter interruption times and fewer insert changes translate into a more predictable production rhythm and better utilisation of machine time.

Stable cutting edge and surface quality under demanding conditions

The rhombic 80° shape combined with a 0.4 mm corner radius delivers a favourable balance between robustness and finish. The geometry supports repeatable dimensional accuracy and a consistent surface texture in serial production. Where interrupted cuts or variable engagement occur, the negative relief of 0° increases edge strength, reducing the risk of chipping and maintaining component quality across batches.

Precise chip control and thermal resilience for safer processes

Equipped with an engineered FM5 chipbreaker and the high‑performance coating, the insert promotes controlled chip formation and evacuation even in sticky or gummy materials. Improved chip control lowers the risk of entanglement and contributes to safer machining conditions. Enhanced thermal stability from the coating also supports higher cutting parameters without compromising edge integrity, enabling efficient material removal rates.

Designed for integration into robust production routines

The insert’s standard CNMG format and the coated carbide concept make it suitable for automated and semi‑automated manufacturing cells, where repeatability matters. The combination of geometry, grade and chip‑forming features supports consistent results across shifts and operators, helping to reduce rework and increase first‑pass yield. For engineering teams seeking dependable inserts for demanding alloys, this solution offers a practical mix of longevity and performance.

FAQ

Which materials are best suited to this insert?
The CNMG120404-FM5 WSM10S insert is optimised for stainless steels and heat‑resistant superalloys (ISO groups M and S), offering improved edge stability when machining these challenging materials.

What does the FM5 chipbreaker achieve in practice?
The FM5 chipbreaker on this Walter Tools insert creates short, manageable chips and supports reliable evacuation, enhancing process safety and reducing the likelihood of chip‑related interruptions.

Is the geometry suitable for interrupted cuts?
Yes. The combination of rhombic 80° geometry and a negative relief angle of 0° provides increased edge strength, making the insert resilient under interrupted or irregular cutting conditions.

How does the Tiger‑tec Silver coating benefit operation?
The Tiger‑tec Silver coating on the WSM10S grade improves thermal resistance and wear behaviour, allowing for more stable cutting parameters and extended edge life in demanding applications.

Can this insert be used in series production with automated machines?
The standard CNMG format and the robust grade of the insert make it well suited for automated and high‑volume environments where repeatability and tool life are priorities.
