CNMG120408-FM5 WMP20G — Walter Tools indexable turning insert, Tiger·tec Gold, for rostfreier Stahl

The CNMG120408-FM5 WMP20G is a Tiger·tec Gold coated indexable turning insert engineered for secure and productive machining of rostfreier Stahl under medium to robust cutting conditions

• Tiger·tec Gold coating for wear resistance
• Optimised FM5 chipbreaker for stable chips
• Rhombic 80° geometry, 0.8 mm corner radius
• Negative 0° rake for robust engagement

Reliable cutting dynamics and process security

The Tiger·tec Gold technology in this grade promotes consistent edge performance and improved wear resistance, which translates into predictable tool life and less process fluctuation. The combination of the FM5 chipbreaker and the coating supports controlled chip formation when working with rostfreier Stahl, a material group known for its toughness and tendency to form built-up edge. The insert’s cutting geometry reduces thermal loading at the cutting edge, so operations remain stable even under intermittent or interrupted cuts, making it a sound choice where process reliability is paramount.

Geometry engineered for strength and versatility

A rhombic 80° shape paired with a 0.8 mm corner radius delivers a favourable balance between edge robustness and versatility in turning applications. The negative 0° rake provides a solid cutting edge for heavier engagement and interrupted cuts, helping to maintain dimensional accuracy and surface finish over longer tool life. The compact insert format supports common toolholder systems and simplifies indexation, while the FM5 chip control promotes predictable evacuation in turning passes, reducing cycle interruptions and tool-change frequency.

Economical machining and application guidance

The Walter Tools grade WMP20G is optimised for machining rostfreier Stahl in medium to robust conditions, offering a productive compromise between wear resistance and edge stability. In many production scenarios this leads to lower overall tooling costs through fewer indexations and more consistent component quality. If uncertainty exists regarding cutting data or application parameters, Metav Werkzeuge provides technical advice and can supply further specification details and recommendations to match the machining task.

FAQ

Is this insert suitable for rostfreier Stahl?
Yes. The CNMG120408-FM5 WMP20G is specifically graded for rostfreier Stahl, with Tiger·tec Gold coating and an FM5 chipbreaker designed to manage chip formation and thermal load on such alloys.

What does the FM5 chipbreaker deliver in practice?
The FM5 chipbreaker in this Walter Tools insert improves chip control and evacuation, which reduces the risk of entanglement and supports stable cutting forces during turning operations.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius increases edge strength and resistance to chipping, offering a more robust cutting edge for semi-finishing and general turning where occasional interruptions occur.

Which toolholders are compatible with the CNMG120408-FM5 form?
The rhombic 80° insert form fits standard indexable turning toolholders designed for CNMG-style inserts; confirm holder compatibility and clamping geometry prior to setup.
