VNMG160408-FM5 WSM20S – Indexable turning insert with Tiger·tec Silver, for rostfreier Stahl and superalloys (Walter Tools)

VNMG160408-FM5 WSM20S is a rhombic 35° indexable turning insert designed for heavy-duty and heat-resistant alloys, offering a coated carbide grade for stable cutting and controlled chip formation

• Tiger·tec Silver coating for high temperature stability
• Optimised FM5 chipbreaker for reliable chip control
• Rhombic 35° shape with 0.8 mm corner radius
• Negative 0° rake for stable cutting performance

Consistent cutting on tough materials for fewer interruptions

The combination of the Tiger·tec Silver coating and the WSM20S grade delivers improved heat resistance and a reliable cutting edge when machining rostfreier Stahl and heat-resistant superalloys. The coated carbide substrate supports stable chip formation, reduces the tendency for built-up edge and extends effective tool life. For production environments where unpredictable tool wear causes downtime, this insert helps to maintain cycle times and component quality without frequent regrinds, so machining remains predictable and cost-efficient.

Precise chip control and predictable surface quality

The FM5 chipbreaker is engineered to produce short, consistent chips on a range of feeds and depths, improving swarf handling and process security. Combined with the rhombic 35° geometry and a 0.8 mm corner radius, the insert balances edge strength and cutting access, enabling smooth surface finishes with fewer passes. The negative 0° rake increases edge stability for intermittent cuts and heavy cross-sections, resulting in fewer edge failures and more consistent part tolerances during serial production.

Practical selection for workshop and production use

As part of the Tiger·tec Silver series, this insert integrates into standard VNMG toolholder systems and is available under the ISO designation VNMG160408-FM5 WSM20S, simplifying inventory and tool choice. The specification supports machining of both the M and S ISO groups (rostfreier Stahl; heat‑resistant superalloys and Titan), which reduces the need for multiple special grades and streamlines process planning. For tailored recommendations on feeds, speeds and holder choice, technical advice is available via Metav Werkzeuge — contact details are provided for rapid consultation.

FAQ

Which materials is this insert best suited for?
The VNMG160408-FM5 WSM20S from Walter Tools is optimised for rostfreier Stahl and for heat‑resistant superalloys and Titan, reflecting the S and M ISO material groups listed for this grade.

How does the FM5 chipbreaker affect production?
The FM5 chipbreaker produces controlled, compact chips that improve swarf evacuation and reduce the risk of chip entanglement, enhancing process reliability with the VNMG160408-FM5 WSM20S insert.

Is the geometry suitable for finishing and heavy cuts?
The rhombic 35° geometry with a 0.8 mm corner radius and negative 0° rake provides a robust edge for heavier engagements while still allowing for good surface quality in finishing passes on demanding materials.

Can this insert be used in standard VNMG toolholders?
Yes, the VNMG form follows the common ISO VNMG specification, making the VNMG160408-FM5 WSM20S compatible with standard toolholders designed for VNMG inserts.

Where to get application data for cutting speeds and feeds?
Application parameters depend on component material, machine rigidity and coolant use; for specific recommendations for the VNMG160408-FM5 WSM20S, Metav Werkzeuge can provide tailored guidance.
