VCMT160404-RM4 VCMT160404-RM4 WSM30S indexable turning insert for stainless steels and superalloys — Walter Tools

VCMT160404-RM4 WSM30S is an indexable turning insert engineered for demanding turning of stainless steels and heat‑resistant superalloys, combining a coated‑carbide grade with a precision chipbreaker and rhombic 35° geometry

• Coated carbide grade WSM30S, Tiger·tec Silver
• Optimised chip control with RM4 chipbreaker
• Rhombic 35° geometry, 7° relief angle
• Corner radius 0.4 mm for consistent edge strength

Consistent performance on stainless steels and superalloys

The combination of the Tiger·tec Silver technology and the WSM30S coated‑carbide grade targets the specific demands of ISO groups M and S. Where stainless steels tend to work‑harden and superalloys generate heat at the cutting zone, this grade provides improved heat resistance and a stable cutting edge. As a result, cycle times can be kept steady and tool changes reduced, supporting a more predictable production rhythm and fewer unplanned stoppages. The insert’s engineered wear behaviour aids in preserving dimensional accuracy over longer runs.

Geometry and chip control that protect productivity

Geometry plays a decisive role in turning. The rhombic 35° shape with 7° relief offers a versatile cutting angle suited to many external turning operations, while the RM4 chipbreaker is designed to produce short, controlled chips in difficult‑to‑cut materials. This leads to safer chip evacuation, reduced risk of built‑up edge and improved surface quality. The corner radius 0.4 mm balances edge strength and finish—large enough to withstand intermittent cuts yet fine enough to maintain consistent part tolerances and surface integrity.

Integration into machining processes and handling benefits

With tolerance class M and a straightforward form factor, the insert integrates easily into standard toolholders for indexable turning, supporting reproducible set‑ups and quick index changes. The coated‑carbide construction lowers thermal load on the cutting edge, contributing to longer tool life and fewer insert swaps, which in turn reduces handling time and keeps operator intervention minimal. For adaptations to specific fixtures or cutting data, Metav Werkzeuge offers application support and can recommend cutting parameters to match production goals.

FAQ

Which materials is this insert best suited for?
The VCMT160404‑RM4 WSM30S grade is designed primarily for stainless steels (ISO group M) and heat‑resistant superalloys and titanium (ISO group S), providing improved thermal resistance and edge stability for these challenging materials.

What advantage does the RM4 chipbreaker offer?
The RM4 chipbreaker controls chip form in long‑chip prone materials, producing manageable chips that protect the cutting zone and help to maintain consistent surface quality during turning with the VCMT160404‑RM4 WSM30S insert.

How does the Tiger·tec Silver coating impact tool life?
The Tiger·tec Silver coating enhances heat resistance and reduces friction at the tool‑workpiece interface, which supports longer cutting edge life and more stable performance in continuous production environments when using this insert.

What aspects of geometry improve surface finish and edge life?
The rhombic 35° geometry together with a 7° relief and 0.4 mm corner radius provides a balance between cutting forces and edge robustness, resulting in repeatable part tolerances and reliable surface finish under varied cutting conditions.
