DNMG150408-RM5 WSM20S — Turning insert, Tiger·tec Silver, Walter Tools (0° negative, Rhombic 55°)

The DNMG150408-RM5 WSM20S is a rhombic 55° turning insert designed for heavy-duty machining of rostfreier Stahl and heat‑resistant alloys, featuring a coated carbide grade from the Tiger·tec Silver series for enhanced edge stability.

• Tiger·tec Silver coated grade WSM20S
• Optimised RM5 chipformer for secure chips
• Negative rake 0° for stable cutting
• Rhombic 55° form with 0.8 mm corner radius

Consistent cutting performance in rostfreier Stahl and superalloys

The WSM20S grade, part of the Tiger·tec Silver family, is a coated carbide designed for applications with high thermal and mechanical load. Its coating improves heat resistance and reduces adhesion on the cutting edge, which supports stable edge life when machining rostfreier Stahl and nickel‑based alloys. In practice, this means fewer interruptions for edge dressing and more predictable tool change intervals, helping to maintain throughput in serial production.

Reliable chip control and process security with RM5

The RM5 chipbreaker is engineered for dependable chip formation on tough materials. By producing short, controllable chips, the insert reduces the risk of chip snarling and workpiece damage, which contributes to steady cycle times and safer turning operations. For production environments where repeatability and minimal rework are essential, the chip control provided by this geometry supports measurable process improvements.

Robust geometry for demanding turning tasks

The rhombic 55° form combined with a 0° (negative) relief angle and a 0.8 mm corner radius increases insert strength and edge support under heavy cuts. This geometry favours stability when encountering interrupted cuts or hard layers and is compatible with standard toolholders that accept DNMG‑style inserts. The design balances cutting force distribution and edge durability, enabling higher feed rates while maintaining surface quality.

Productivity and predictable tool consumption

Using a coated carbide grade tuned for hard-to‑cut materials leads to longer in‑service life and lower tooling costs per component. The combination of the WSM20S grade and the RM5 chipformer reduces unscheduled downtime and results in a more economical turning process over time. For workshops seeking both performance and repeatability, this insert supports reliable cycle planning and contributes to overall machining efficiency.
