Take advantage of the combination of Tiger‑tec Silver coating and the WSM20S grade for stable chip control and extended tool life; the rhombic 55° geometry with 0° negative rake and a 0.4 mm corner radius supports consistent surface quality in demanding stainless and heat‑resistant alloy turning operations — order original Walter Tools inserts via Metav Werkzeuge or consult our specialists for application advice.

DNMG150404‑MM5 WSM20S indexable turning insert — Tiger‑tec Silver coating, for stainless steels and superalloys (Walter Tools)

A DNMG150404‑MM5 WSM20S indexable insert engineered for reliable machining of stainless steel and heat‑resistant superalloys, combining a robust chipbreaker with a compact rhombic geometry for secure cutting across roughing and near‑finish operations.

• Tiger‑tec Silver coated carbide grade WSM20S
• Optimised MM5 chipbreaker for secure chips
• Rhombic 55° geometry with 0° negative rake
• Suitable for stainless steel and superalloys

Increased productivity through coating and grade optimisation

The Tiger‑tec Silver coating together with the WSM20S grade is designed to resist abrasive wear and to maintain a stable cutting edge when machining stainless steel and high‑temperature alloys. This combination reduces flank wear and supports a predictable tool life, which in turn lowers process interruptions and increases component throughput. The coated cemented carbide substrate was developed for enhanced thermal resistance; as a result, machining parameters can be stabilised and cycle times improved without compromising surface integrity.

Geometry and chip control that protect component quality

The rhombic 55° insert shape and the MM5 chipbreaker deliver controlled chip formation and good access to interrupted or profile cuts. A 0.4 mm corner radius provides a balance between edge strength and achievable surface finish, while the 0° negative rake angle increases cutting edge robustness for tougher engagement conditions. These geometric attributes mean the insert is suitable for a range of turning tasks where consistent surface quality and predictable dimensional results are required.

Application focus and process reliability for production workshops

Intended for the machining of stainless steel (ISO group M) and heat‑resistant alloys (ISO group S), this insert supports operations where material toughness and thermal load are significant factors. Stable chip evacuation, promoted by the MM5 chipformer, reduces the risk of built‑up edge and tool damage, helping to minimise rework. The solution is well suited to batch production and mixed‑lot environments where repeatability and tool‑change predictability are priorities; technical consultation via Metav Werkzeuge can help match cutting data to the specific machine and workpiece material.

FAQ

What materials is this insert best suited for?
The DNMG150404‑MM5 WSM20S insert is optimised for stainless steel (ISO group M) and for heat‑resistant superalloys (ISO group S), offering thermal stability and reliable chip control for these challenging materials.

How does the Tiger‑tec Silver coating improve performance?
The Tiger‑tec Silver coating enhances wear resistance and heat management on the cutting edge of the insert, helping the WSM20S grade to provide longer tool life and steadier performance under elevated cutting temperatures.

What is the effect of the MM5 chipbreaker?
The MM5 chipbreaker is engineered for consistent chip segmentation and evacuation; this reduces the risk of built‑up edge and facilitates stable machining in both roughing and more delicate cutting passes.

Which cutting tasks benefit most from the 0.4 mm corner radius?
A 0.4 mm corner radius offers improved edge strength for interrupted cuts and allows acceptable surface finish in semi‑finishing and finishing applications, without overly increasing cutting forces.

Is this an original Walter Tools product and where to obtain it?
The insert is an original Walter Tools product — genuine items and application advice can be obtained through Metav Werkzeuge, who can support grade and geometry selection for specific production needs.
