CNMG120408‑MS3 WSM20S indexable turning insert — for stainless steels and superalloys, Walter Tools

The CNMG120408‑MS3 WSM20S is a rhombic 80° indexable turning insert designed for heavy‑duty finishing and semi‑finishing of stainless steels and heat‑resistant superalloys.

• Tiger‑tec Silver coating for high process security
• Optimised MS3 chipbreaker for stable chip control
• Rhombic 80° form with 0.8 mm corner radius
• Suitable for stainless steel and superalloys (M/S)

Reliable machining of demanding materials with predictable edge behaviour

The combination of the WSM20S grade and the Tiger‑tec Silver coating provides a rational foundation for consistent production results when working with tough, heat‑sensitive alloys. The coated carbide substrate supports stable chip formation, reducing the risk of built‑up edge and thermal overload; this translates into fewer interruptions on the shop floor and improved process security. For operations that require repeatable part tolerances, the coated grade offers improved surface finish and tool life compared with uncoated grades, making it a cost‑effective choice across small and large batch runs.

Geometry engineered to prolong tool life and improve surface quality

The insert’s rhombic 80° geometry and 0.8 mm corner radius deliver a balanced combination of strength and cutting performance. A 0° negative rake increases edge robustness in interrupted cuts and heavy feeds, while the MS3 chipbreaker is optimised to control swarf and evacuate chips reliably. These features reduce rework and inspection cycles by helping to maintain a consistent cutting edge, which benefits productivity and lowers overall machining cost per component. The result is a measurable improvement in both component finish and tool longevity.

Easy integration into existing turning tool systems and workflows

With the standard CNMG form factor and the series’ focus on process stability, the insert integrates smoothly into established tooling setups, minimising change‑over time. The grade’s suitability for group M (stainless steels) and group S (heat‑resistant superalloys and titanium) makes inventory management simpler by covering a wide material range with one insert family. Technical enquiries regarding application parameters or grade selection can be addressed quickly by the supplier to ensure the insert performs as intended in specific cutting conditions.

FAQ

What materials is this insert best suited for?
The CNMG120408‑MS3 WSM20S insert is designed primarily for stainless steels (M) and heat‑resistant superalloys/titanium (S), where the Tiger‑tec Silver coating aids thermal resistance and chip control.

How does the MS3 chipbreaker benefit machining?
The MS3 chipbreaker provides consistent chip formation and evacuation for finishing and semi‑finishing cuts, reducing the likelihood of built‑up edge and improving process stability with the CNMG120408‑MS3 insert.

Can this insert withstand interrupted cuts?
Yes. The combination of a 0° negative rake and the rhombic 80° geometry gives the insert enhanced edge strength suited to interrupted cuts and heavy feed conditions.

Is the insert compatible with standard CNMG tool holders?
The insert follows the CNMG form factor and is compatible with standard CNMG tool holders; correct clamping and seat cleanliness ensure repeatable performance.

What improvements in surface finish can be expected?
The WSM20S grade and coating improve edge stability and reduce thermally induced roughness, resulting in a more consistent surface finish compared with uncoated alternatives.
