TNMG160404-FM5 WMP20S indexable turning insert for rostfreier Stahl — Walter Tools

TNMG160404-FM5 WMP20S is a triangular indexable insert designed for turning operations in rostfreier Stahl and similar demanding materials

• Tiger·tec Silver coating for extended tool life
• Optimised for rostfreie Stähle (M) and stable chips
• Triangle 60° form with 0.4 mm corner radius
• FM5 chipbreaker for consistent surface finish

Long-lasting performance for demanding rostfreier Stahl turning

The insert combines the Tiger·tec Silver coating with the WMP20S grade to deliver enhanced wear resistance and stable edge behaviour when machining rostfreier Stahl. The coated carbide construction supports sustained cutting under the high temperatures and adhesion tendencies typical of these alloys, reducing the frequency of tool changes and helping to maintain consistent component tolerances. By favouring a cutting grade tuned to the material group M, the insert promotes secure chip formation and fewer built-up edges, which in turn helps to preserve machine uptime and improve overall process efficiency.

Geometry and chip control that reduce rework and improve surface quality

A triangle 60° configuration paired with a 0.4 mm corner radius provides a reliable balance between strength and form accuracy for turning profiles. The FM5 chipbreaker is engineered to control swarf and support even chip evacuation in interrupted or continuous cuts, lowering the risk of re-cutting and surface defects. The 0° (negative) relief angle offers a robust cutting edge for heavier feed and depth of cut conditions, enabling stable performance on components where repeatability matters. These geometry choices make the insert suitable for a range of turning tasks where surface finish and dimensional stability are priorities.

Process security, workshop efficiency and integration into production

Designed for reliable, repeatable results, this insert supports productive machining cycles and reduced scrap rates. The combination of coating technology and dedicated chip control contributes to predictable tool life and machining behaviour, which simplifies process planning and reduces inspection overhead. For application support or to confirm suitability in a specific turning cell, Metav Werkzeuge provides technical advice and can assist with selecting matching toolholders and cutting parameters; contact details are available for straightforward consultation. The insert is a practical choice where consistent surface quality and stable manufacturing flow are required.

FAQ

What materials is this insert intended for?
The TNMG160404-FM5 WMP20S insert from Walter Tools is optimised for rostfreier Stahl and performs reliably under the characteristic thermal and adhesion challenges of these alloys.

What does the WMP20S grade indicate?
WMP20S denotes Walter’s coated-carbide grade within the Tiger·tec Silver family, selected for stable chip formation and wear resistance when machining material group M (rostfreier Stahl).

How does the FM5 chipbreaker improve turning results?
The FM5 chipbreaker provides controlled chip formation and evacuation, helping to reduce re-cutting and deliver a more consistent surface finish when using the TNMG insert.

Is the TNMG160404-FM5 compatible with standard TNMG toolholders?
The triangular 60° TNMG form matches standard toolholders for TNMG inserts; verify the seat and clamping type to ensure correct fit for the intended holder.
