VCMT110304-RM4 WSM30S turning insert — Tiger·tec Silver, RM4 chipbreaker (Walter Tools)

VCMT110304-RM4 WSM30S is a coated turning insert designed for secure chip control and long edge life when machining stainless steel and heat‑resistant superalloys

• Tiger·tec Silver coating for robust edge life
• Optimised RM4 chipbreaker for stable chips
• Rhombic 35° geometry for versatile turning
• Suitable for stainless steel and superalloys

Consistent performance in demanding materials

The VCMT110304‑RM4 WSM30S insert combines a Tiger·tec Silver coating with a coated carbide substrate to deliver sustained performance when turning materials that generate heat and strain the cutting edge. The grade WSM30S is formulated for stainless steel and high‑temperature alloys, promoting secure chip formation where workpiece ductility and built‑up edge are typical challenges. The RM4 chipbreaker is engineered to stabilise chips under interrupted or continuous cuts, which reduces tool‑holder vibration and contributes to predictable machining cycles. This results in fewer unplanned tool changes and improved process reliability for production environments.

Geometry engineered for surface quality and flexibility

The insert’s Rhombic 35° form and a 0.4 mm corner radius offer a balanced compromise between strength and finish capability. A 7° clearance angle reduces rubbing while maintaining cutting stability, which is particularly beneficial during semi‑finishing passes. The compact insert size and profile enable access to a variety of turning tasks, including light profiling and shoulder work, with the RM4 chipbreaker optimised to produce short, controllable chips that are easier to evacuate from the cut. For shops aiming to combine repeatable surface quality with efficient chip handling, this geometry supports consistent results across batch production.

Process security, economics and tool life

Delivered within the Tiger·tec Silver series, the insert benefits from a coating system that enhances thermal resistance and protects the cutting edge against abrasion and adhesion. The combination of coated carbide and a tailored chipbreaker reduces the rate of edge deterioration, improving cycle time efficiency and lowering total machining cost per component. Walter Tools’ manufacturing standards and the insert’s microgeometry ensure reproducible cutting performance, making it suitable for setups where minimised downtime and stable tool life are priorities. For production lines machining stainless steel or nickel‑based alloys, the insert provides a technically sound choice that supports predictable component quality.

FAQ

What materials is this insert best suited for?
The VCMT110304‑RM4 WSM30S insert is intended for stainless steel and heat‑resistant superalloys, with the WSM30S grade optimised to support secure chip formation and thermal resistance in such materials.

How does the RM4 chipbreaker affect machining?
The RM4 chipbreaker produces short, controlled chips and promotes stable cutting, which helps to reduce tool‑holder vibration and supports consistent surface finish during turning operations.

Is the Rhombic 35° geometry suitable for finishing?
Yes; the Rhombic 35° form combined with a 0.4 mm corner radius provides a balance between edge strength and achievable surface quality, making it suitable for semi‑finishing and finishing passes where access permits.

Does the Tiger·tec Silver coating extend tool life?
The Tiger·tec Silver coating increases thermal resistance and abrasion protection of the coated carbide substrate, which contributes to longer edge life and more predictable performance in demanding cutting conditions.

Can this insert be used for titanium machining?
The WSM30S grade is developed for heat‑resistant alloys and, depending on tool geometry and process parameters, can be applied to titanium and similar difficult‑to‑machine materials.
