DNMG150608-FM5 WSM20S indexable turning insert — Walter Tools, Tiger·tec Silver, for rostfreier Stahl and superalloys

DNMG150608-FM5 WSM20S is an indexable turning insert designed for reliable performance in rostfreier Stahl and heat-resistant alloys, offering a coated carbide grade optimised for stable chip formation and long tool life

• Tiger·tec Silver coated carbide for wear resistance
• WSM20S grade for rostfreier Stahl and superalloys
• Rhombic 55° form for versatile insert positioning
• FM5 chipbreaker for consistent chip control

Increased process security for demanding materials

The WSM20S grade, integrated in the Tiger·tec Silver series, is a coated carbide engineered to cope with the specific challenges of rostfreier Stahl and heat-resistant superalloys. Its coating system and substrate combination support stable chip formation, reduce built-up edge and extend the effective cutting life. For production environments where part consistency and reduced rework are priorities, this insert delivers measurable improvements in process reliability and reproducibility while maintaining acceptable surface quality.

Geometry tailored to durability and surface finish

The rhombic 55° format combined with a 0° (negative) rake angle and a 0.8 mm corner radius provides a robust cutting edge that resists chipping under interrupted cuts and heavy engagement. The FM5 chipbreaker is designed to promote predictable chip flow and reduce vibration, which aids in achieving consistent finishes and dimensional control. Thanks to this geometry, toolholders maintain stability and cutter changes become a controlled, low-risk step in the workflow.

Practical application advice and efficiency gains

This insert is intended for turning operations where material behaviour demands both edge stability and thermal resistance. Use in medium to heavy finishing passes or light roughing of difficult-to-machine alloys is typical; the combined properties of the coating and substrate help to lower downtime through fewer indexings and predictable wear patterns. Pairing the insert with a properly configured holder and a cooling strategy tuned to the workpiece material results in longer service intervals and improved productivity.

FAQ

Which materials is this insert suitable for?
The DNMG150608-FM5 WSM20S is suitable for rostfreier Stahl (ISO group M) and for heat-resistant superalloys and titanium (ISO group S), thanks to the Tiger·tec Silver coated carbide and the WSM20S grade design.

What advantage does the FM5 chipbreaker provide?
The FM5 chipbreaker promotes controlled chip formation and evacuation, improving consistency in cutting forces and surface finish while reducing the risk of entangling chips.

How does the 0° negative rake affect machining?
A 0° (negative) rake enhances edge strength and resistance to chipping, making the insert better suited to interrupted cuts and tougher engagements where a robust cutting edge is required.

Which toolholders are compatible with this insert?
This insert conforms to the DNMG seating standard and is compatible with turning toolholders designed for DNMG inserts; verify seat size and clamping method with the holder specification.
