CNMG120408-FM5 WMP20S — Indexable turning insert, Tiger‑tec Silver coating by Walter Tools

A CNMG120408-FM5 WMP20S indexable insert designed for medium to robust machining of rostfreier Stahl, offering stable cutting behaviour and predictable tool life for production environments

• Tiger‑tec Silver coating for long edge life
• Optimised for rostfreier Stahl machining
• Rhombic 80° geometry for versatile turning
• FM5 chipbreaker for stable chip control

High-performance coating for consistent productivity

The Tiger‑tec Silver coating combines wear resistance with thermal stability to extend the service intervals between edge changes. For operations on rostfreier Stahl, which typically generates heat and tends to form built-up edge, this coated carbide grade promotes stable chip formation and reduces the risk of premature flank wear. The result is a measurable increase in productive cutting time and fewer interruptions for tool indexing, supporting cost-effective batch production.

Geometry engineered for secure cutting and chip guidance

The Rhombus 80° shape with a 0.8 mm corner radius and negative 0° relief creates a robust cutting edge suited to transverse and profile turning tasks. The FM5 chipbreaker is engineered to control chip flow under medium to heavy cut conditions, lowering the incidence of entangled swarf and minimising surface defects. This geometry translates into more predictable process windows, reduced rework and improved cycle-time stability on rostfreier Stahl components.

Robust substrate and grade for demanding applications

WMP20S is a coated carbide grade within the Tiger‑tec Silver family formulated to handle the typical challenges of rostfreier Stahl: toughness, adhesive tendencies and high thermal loads. The combination of substrate and coating yields a reliable cutting edge across varied feed and speed ranges. When integrated into an optimised machining strategy, the insert contributes to repeatable surface finishes and consistent dimensional accuracy over long production runs.

Practical integration into the workshop and process benefits

Compatibility with common CNMG toolholders and standard clamping systems allows straightforward replacement and inventory management. The insert’s balanced performance helps reduce tool-change frequency and supports leaner tooling stocks. For process planning, the data supplied (geometry, chipbreaker and grade) can be used to define cutting parameters that favour both productivity and component quality, making the insert a pragmatic choice for serial turning of rostfreier Stahl parts.

FAQ

What materials is this insert intended for?
The CNMG120408-FM5 WMP20S insert by Walter Tools is optimised for machining rostfreier Stahl and is specified for medium to robust cutting conditions.

How does the FM5 chipbreaker affect machining?
The FM5 chipbreaker on this Walter Tools insert improves chip control and reduces the likelihood of built-up edge when machining rostfreier Stahl, promoting a steadier surface finish.

What does the negative 0° relief mean in practice?
A negative 0° relief provides a stronger cutting edge and better resistance to edge chipping under heavier cuts; the CNMG120408-FM5 geometry is therefore suited to robust turning operations.

Is the insert compatible with common CNMG toolholders?
Yes, the CNMG120408-FM5 WMP20S is manufactured to standard CNMG dimensions and is compatible with standard holders designed for that ISO designation.

What benefit does the Tiger‑tec Silver coating provide?
The Tiger‑tec Silver coating increases wear resistance and thermal stability, extending tool life and improving consistency when turning rostfreier Stahl.
