WNMG060408-MM5 WSM20S – Indexable turning insert (Tiger‑tec Silver) for stainless steel & superalloys | Walter Tools

The WNMG060408-MM5 WSM20S is an 80° Trigon indexable insert from the Tiger‑tec Silver series, designed for robust turning of stainless steels and heat‑resistant superalloys in demanding production environments.

• Tiger‑tec Silver coated carbide grade WSM20S
• Optimised for stainless steel and superalloys
• Trigon 80° geometry for robust cutting edges
• 0.8 mm corner radius with 0° negative rake

Consistent edge performance in demanding materials

The coated carbide grade WSM20S from the Tiger‑tec Silver family is formulated for applications where temperature and material toughness challenge the tool life. The combination of a thermally stable coating and a wear‑resistant substrate promotes stable cutting edge behaviour, which reduces the risk of built‑up edge and unplanned rework when turning stainless steels or nickel‑based alloys. This translates into predictable component quality and fewer interruptions on the shop floor, supporting steady production flow and repeatable results.

Geometry that improves surface quality and chip control

The Trigon 80° profile with the MM5 chipbreaker and a 0.8 mm corner radius provides a balance between edge strength and surface finish. The negative 0° rake enhances robustness under heavy engagement, while the chipbreaker is designed to split and control chips generated from tough materials. Controlled chip formation reduces workpiece marking and helps maintain consistent surface integrity; the result is better first‑pass quality and less downstream finishing.

Raise productivity with fewer tool changes and higher process security

A coated carbide insert like this one extends effective cutting life compared with uncoated grades, increasing uptime and lowering tool consumption per component. The stable edge and reliable wear behaviour contribute to process security and predictable tool change intervals, which in turn improve overall shop productivity. For production setups where tool availability and cycle time matter, this insert supports economical machining by reducing changeover frequency and maintaining consistent part tolerances.

Practical selection and shop‑floor integration

The ISO designation and indexable format make integration into existing tool holders straightforward; the insert format is compatible with common turning systems. The size and thickness data allow planners to match the insert to the holder and the intended operation type. For practical application, the WNMG060408-MM5 WSM20S performs best when cutting parameters are adapted to the material class and machine capability—Metav Werkzeuge can advise on parameter windows and holder choices for a specific turning centre or lathe. The insert suits operations from robust semi‑finishing to controlled finishing, depending on feed and speed.

FAQ

Which materials are recommended for this insert?
The WNMG060408-MM5 WSM20S is intended for stainless steels (M) and heat‑resistant superalloys/titanium (S); the WSM20S grade and Tiger‑tec Silver technology help manage heat and support stable chip formation when machining these classes.

What is the role of the MM5 chipbreaker?
The MM5 chipbreaker shapes and shortens chips produced during cutting, aiding chip control and evacuation. For tough materials, this reduces the risk of long stringy chips and helps preserve surface quality.

Can this insert be used for finishing stainless steel components?
Yes—depending on machine rigidity and cutting parameters, the Trigon 80° geometry with a 0.8 mm corner radius can achieve good surface quality; selection of feed and speed should be matched to the material and desired finish.

How does the 0° negative rake affect cutting performance?
A 0° negative rake increases edge robustness and resistance to chipping under heavy engagement, making the insert suitable for demanding turning where edge strength and process security are priorities.

Is Tiger‑tec Silver a coating or a substrate technology?
Tiger‑tec Silver denotes a coated carbide technology combining a wear‑resistant coating with a tailored substrate; this improves thermal stability and wear resistance in high‑temperature turning operations.
