DCMT070208-RM4 WSM20S – Indexable turning insert, Tiger·tec Silver, Walter Tools

The DCMT070208-RM4 WSM20S is an indexable turning insert engineered for secure, repeatable machining of stainless steel and heat‑resistant superalloys in demanding production environments.

• Tiger·tec Silver coated for high process security
• Optimised RM4 chipbreaker for stable chip control
• Rhombic 55° geometry for versatile turning operations
• 0.8 mm corner radius with 7° clearance for edge stability

Longer tool life through thermal and wear resistance

The combination of the Tiger·tec Silver coating with the WSM20S grade creates a coated carbide system designed to withstand the high temperatures and adhesive tendencies of stainless steel. This results in improved edge stability and reduced flank wear compared with uncoated grades, so fewer indexings and longer production runs are achievable. For production planners this means more predictable tool cycles and fewer unscheduled interventions while machining tough alloys.

Reliable chip control for uninterrupted turning operations

The insert’s RM4 chipbreaker is optimised for secure chip control, especially when cutting materials that tend to form long or welded chips. A reliable chip geometry reduces the risk of rework, tool damage and machine stoppages; it also supports consistent surface quality on the workpiece. The insert’s chip evacuation performance contributes directly to higher machine uptime and a smoother, more efficient workflow on the shop floor.

Geometry that combines versatility with stability

The rhombic 55° form and a 0.8 mm corner radius provide a balance between cutting strength and flexibility for a wide range of turning tasks. The moderate nose radius supports finishing while retaining adequate robustness for light roughing, and the 7° clearance helps to prevent rubbing and build‑up of edge material. This geometry allows the insert to be used for external turning, light profiling and facing operations with improved repeatability.

Practical selection and integration in production

With a tolerance class M and an execution suited to demanding materials, the insert is a practical choice for series production and jobbing alike. The WSM20S grade is specifically targeted at stainless steel and the S group of heat‑resistant alloys and titanium, offering a good compromise between wear resistance and toughness. For cutting parameters, start with conservative feeds and speeds and increase once process behaviour is proven; further optimisation and application tables are available on request. Technical queries are welcome — Metav Werkzeuge can provide cutting data and application support by email or phone.

FAQ

Which materials is this insert best suited for? The DCMT070208-RM4 WSM20S insert from Walter Tools is designed principally for stainless steel and for heat‑resistant superalloys and titanium, providing controlled wear and thermal resistance in these groups.

How does the RM4 chipbreaker improve machining? The RM4 chipbreaker on this insert promotes reliable chip control and evacuation, reducing the likelihood of chip entanglement and enabling steadier surface finishes during continuous turning operations.

What advantages does the Tiger·tec Silver coating bring? Tiger·tec Silver on the WSM20S grade enhances thermal stability and wear resistance, which together contribute to longer tool life and consistent cutting performance when machining demanding materials.

Why choose a rhombic 55° geometry and 0.8 mm corner radius? The rhombic 55° geometry combined with a 0.8 mm corner radius offers a compromise between cutting strength and finishing capability, suitable for a variety of turning applications while maintaining edge robustness.

Are there any recommendations for initial cutting data? Begin with conservative speeds and feeds tailored to stainless steel or superalloys and increase gradually as process behaviour stabilises; Metav Werkzeuge can supply application sheets and cutting parameters for the WSM20S grade.
