DNMG150412-MM5 WSM20S turning insert — Tiger·tec Silver, 0° negative rake — Walter Tools

The DNMG150412-MM5 WSM20S is a coated indexable turning insert designed for demanding turning of stainless steel and heat-resistant alloys

• Tiger·tec Silver grade for thermal resistance
• Optimised MM5 chipbreaker for stable chips
• Rhombic 55° form with 1.2 corner radius
• 0° negative rake for robust edge support

Stable cutting in heat‑generating materials

The WSM20S grade in the Tiger·tec Silver family combines a wear-resistant coating and substrate balance that promotes stable chip formation and reduces edge build-up when machining stainless steel or nickel‑base alloys. The tailored coating lowers friction and improves heat management at the cutting zone, which translates into longer in‑service edge life and fewer unscheduled tool changes. This yields measurable gains in productivity and process predictability for serial or batch turning operations.

Geometry engineered for repeatable surface quality

The rhombic 55° plate form and the 1.2 corner radius offer a compromise between strength and finishing capability: the geometry supports heavier cuts while maintaining a regular contact line for consistent surface finish. The insert’s MM5 chipbreaker is optimised for the tendencies of stainless and high‑temperature alloys, producing controlled chip shapes that evacuate reliably and protect the cutting edge. With a 0° negative rake the design prioritises edge security under interrupted cuts and unstable feeds, reducing the risk of chipping in roughing applications.

Process integration and predictable performance

As a series item from Tiger‑tec Silver, the insert is intended for stable, productive turning cycles where reproducible results matter. The combination of grade and chip control makes the insert suitable for both high‑temperature alloy roughing and finishing passes in stainless steel, reducing cycle time and scrap. Technical data sheets and recommended cutting parameters are available to align speeds and feeds with machine capability; Metav Werkzeuge can support selection and provide cutting charts to match the insert to specific workpiece conditions. The result is improved process security and a consistent surface quality across batches.

FAQ

Is this insert suitable for machining stainless steel?
Yes. The WSM20S grade in the Tiger·tec Silver series is expressly designed for stainless steel, supporting stable chip formation and reduced built‑up edge under the high temperatures typical of such materials.

Which applications benefit most from this insert?
The insert is suited to turning operations that require robust edge support and reliable chip control, such as heavy roughing and semi‑finishing in stainless steel and heat‑resistant superalloys.

What does the MM5 chipbreaker deliver in practice?
The MM5 chipbreaker promotes controlled chip shapes for efficient evacuation, which helps maintain cutting edge integrity and reduces interruptions caused by poor chip management.

How does the 0° negative rake affect cutting?
A 0° negative rake increases edge strength and resistance to mechanical shock, which is advantageous for interrupted cuts or when machining tough, work‑hardening materials.

Can Metav Werkzeuge supply cutting data for this insert?
Yes. Metav Werkzeuge can provide recommended speeds, feeds and cutting conditions matched to the Walter Tools WSM20S grade and the specific stainless steel or alloy being machined.
