DNMG110408-MU5 WSM20S – indexable turning insert, Tiger·tec Silver, Walter Tools

The DNMG110408-MU5 WSM20S is a rhombic 55° indexable turning insert engineered for reliable machining of stainless steels and heat‑resistant superalloys in demanding production environments.

• Tiger·tec Silver coating for high thermal resilience
• Optimised MU5 chipbreaker for stable chip control
• Rhombic 55° form with 0.8 mm corner radius
• Suited for stainless steel and superalloys

Consistent performance in hard‑to‑cut materials

The combination of the WSM20S grade and the Tiger·tec Silver coating provides a resilient cutting edge for materials that generate heat and work‑hardening. Thanks to a coated carbide substrate, the insert sustains edge stability under thermal stress, reducing the tendency for built‑up edge when turning stainless steels. This translates into fewer interruptions for edge dressing and a smoother process flow, which supports predictable cycle times and improved component quality.

Improved chip control and surface quality

The integrated MU5 chipbreaker has been optimised for secure chip formation when machining tough alloys. Controlled chip segmentation reduces the risk of entanglement and promotes uninterrupted cutting, which benefits both automatic and manual operations. As a result, finishing passes can achieve better surface integrity, lowering the need for secondary operations and increasing first‑pass yield in series production.

Geometry that boosts productivity and tool life

The rhombic 55° shape and 0.8 mm corner radius offer a balanced compromise between strength and cutting versatility. The negative 0° rake (negative geometry) enhances edge robustness for medium to heavy cuts, while the compact corner radius supports repeatable dimensional results on turned features. For workshops focused on productivity, this geometry helps maintain stable tool life and consistent component tolerances across batches.
