CNMG120404-MS3 WSM20S Tiger·tec Silver indexable insert – Rhombic 80°, 0° negative rake (Walter Tools)

The CNMG120404-MS3 WSM20S is an indexable turning insert engineered for machining stainless steels and heat‑resistant superalloys, offering a robust coated‑carbide grade within the Tiger·tec Silver series.

• Tiger·tec Silver coating WSM20S
• For stainless steels & superalloys
• Rhombic 80° form, negative 0° rake
• MS3 chipbreaker for controlled chips

High-performance grade for challenging materials

The WSM20S grade, part of the Tiger·tec Silver family, is a coated carbide engineered for difficult‑to‑cut materials. Its coating system and substrate combination deliver improved thermal stability and wear resistance, which results in longer tool life and fewer indexings in serial production. Because the grade supports secure chip formation, process stability is increased when turning tough stainless steels and heat‑resistant alloys, helping to maintain component quality during sustained runs.

Geometry and chip control for consistent turning results

The rhombic 80° plate shape with a 0° negative rake and a 0.4 mm corner radius provides a balance between edge strength and achievable surface finish. The MS3 chipbreaker is designed to support controlled chip segmentation under moderate cutting depths, which reduces the risk of entangling swarf and improves evacuation in confined toolpaths. When mounted in compatible toolholders, the CNMG geometry enables repeatable seating and predictable cutting forces, translating into consistent dimensional accuracy and reduced vibration.

Practical benefits for workshop productivity

With a tolerance class of M and execution G, this insert is produced for reliable interchangeability and stable mounting in standard tool assemblies. The combination of the coated WSM20S grade and the MS3 chipbreaker reduces downtime from premature edge failure and supports steady production rates, especially on components made from stainless steels or superalloys. Application guidance and cutting‑parameter recommendations are advised for optimising feed and speed; matching insert geometry to the turning task will maximise economy and surface quality.

FAQ

What materials is this insert suitable for?
The CNMG120404-MS3 WSM20S insert is suitable for stainless steels and heat‑resistant superalloys (material classes S and M), as indicated by the WSM20S grade properties.

What advantage does the Tiger·tec Silver series provide?
The Tiger·tec Silver treatment combines a resilient coating and substrate to improve thermal stability and wear resistance, which extends edge life under demanding turning conditions.

How does the MS3 chipbreaker affect machining?
The MS3 chipbreaker promotes controlled chip formation and easier evacuation, reducing the likelihood of swarf buildup and supporting stable cutting forces in turning operations.

Is the CNMG120404-MS3 geometry compatible with standard toolholders?
Yes, the CNMG120404 geometry is a standard indexable insert form; correct seating and clamping in a compatible holder are required to ensure the rated performance and tolerance class M.

What cutting parameters are recommended for best results?
Cutting parameters depend on the workpiece material and machine rigidity; for the WSM20S grade, moderate speeds with steady feeds and appropriate coolant or dry‑cutting strategy are typically advised—Metav Werkzeuge can provide tailored recommendations.
