CNMG120404-MS3 WSM30S indexable turning insert – Tiger‑tec Silver, for rostfreier Stahl and superalloys, Walter Tools

The CNMG120404-MS3 WSM30S is a rhombic 80° indexable turning insert with a negative 0° rake, designed for demanding turning of rostfreier Stahl and heat‑resistant superalloys.

• Tiger‑tec Silver coating for heat resistance
• Suitable for rostfreier Stahl (ISO M)
• Rhombic 80° geometry for versatile turning
• MS3 chipbreaker for stable chip control

Increased process reliability through thermal stability and wear resistance

The Tiger‑tec Silver technology combined with the WSM30S grade delivers a coated carbide chemistry optimised for applications where heat generation and built‑up edge are critical. The coating improves thermal resistance and reduces flank wear, which means longer tool life and fewer insert changes during production. With the negative 0° rake and a stable chipbreaker, the insert provides consistent cutting forces and reduced vibration, supporting a steady machining process when working with rostfreier Stahl and other hard‑to‑machine alloys.

Geometry tuned for consistent surface quality and edge life

The rhombic 80° form and the 0.4 mm corner radius give a balance between form accuracy and edge strength. This geometry is suited to general turning operations where a robust cutting edge is needed without compromising on surface finish. The insert’s size and thickness deliver predictable contact conditions at the tool tip, contributing to repeatable results and simplified tool set‑up. Clear geometry choices like these reduce the need for frequent parameter adjustments and improve first‑pass yield on serial production.

Practical benefits for productive turning operations

By combining an advanced coating with a defined chipbreaker (MS3) and a strong cutting edge, this insert supports higher stability and predictable chip formation under mixed cutting conditions. That leads to fewer interruptions for manual clearing of chips and more continuous cutting times, increasing throughput. The result is measurable efficiency gains in component output and lower overall tooling consumption, which contributes to a better return on tooling investment in the medium term.

Recommended applications and material scope

This insert is particularly intended for turning of rostfreier Stahl (ISO M) and is also suitable for certain heat‑resistant superalloys and titanium (ISO S) depending on cutting strategy and machine capability. The combination of coating and geometry is aimed at operations where thermal loads and material toughness challenge the cutting edge. For specific machine‑and‑workpiece combinations, Metav Werkzeuge’s technical advisers can help determine the optimal cutting data and holder selection to exploit the insert’s strengths.

FAQ

What materials is this insert best suited for?
The CNMG120404‑MS3 WSM30S indexable turning insert from Walter Tools is optimised for rostfreier Stahl (ISO M) and can also be applied to heat‑resistant superalloys and titanium (ISO S) with suitable machining parameters.

How does the Tiger‑tec Silver coating improve performance?
Tiger‑tec Silver on the WSM30S grade increases thermal resistance and reduces wear at the cutting edge, helping the insert maintain a consistent profile and longer life when machining tough, heat‑generating materials.

Which geometry features support surface finish and edge strength?
The rhombic 80° form and the 0.4 mm corner radius give the insert mechanical robustness while enabling a good surface finish; the negative 0° rake enhances edge stability under high loads.

Is the MS3 chipbreaker suitable for continuous turning operations?
Yes, the MS3 chipbreaker is engineered for controllable chip formation in a range of cutting scenarios, making the insert well suited to semi‑continuous and continuous turning processes.

Can Metav Werkzeuge advise on cutting data and holders for this insert?
Metav Werkzeuge provides application advice for integrating the Walter Tools CNMG120404‑MS3 WSM30S into production, including recommended holders and cutting parameters tailored to the workpiece and machine.
