DNMG150408-FW5 WSM20S indexable turning insert by Walter Tools — Tiger‑tec Silver, rhombic 55°

The DNMG150408-FW5 WSM20S is a Tiger‑tec Silver-coated indexable turning insert engineered for heavy‑duty turning of stainless steels and heat‑resistant superalloys.

• Tiger‑tec Silver coating for thermal stability
• Optimised FW5 chipbreaker for secure chip control
• Rhombic 55° shape for versatile turning
• 0.8 mm nose radius for fine profile accuracy

Process-stable performance for demanding materials

The combination of a coated carbide substrate and the Tiger‑tec Silver technology delivers enhanced thermal resistance and wear behaviour when machining hard‑to‑cut alloys. This results in a stable cutting edge that reduces unexpected tool changes and supports consistent cycle times. The grade WSM20S, designed for materials classified as M and S according to ISO 513, is optimised for applications where heat build‑up, edge wear and workhardening are critical factors. As a consequence, tool life is extended under the higher temperatures encountered when turning stainless steels and superalloys, improving overall process economy.

Reliable chip control and surface quality during turning

Thanks to the FW5 chipbreaker, chip formation is guided into predictable, short chips that are easier to evacuate from the cutting zone. Predictable chip flow reduces rework and helps maintain surface finish, which is particularly important when turning corrosion‑resistant components or parts for the aerospace and energy sectors. The negative relief geometry (negative 0°) and rhombic 55° insert shape support robust clamping and allow stable cutting at varied depths of cut, delivering repeatable dimensional accuracy and fewer surface defects across production batches.

Geometry explained: why nose radius and relief matter

The 0.8 mm nose radius balances profile detail and edge strength: it permits fine contouring while providing sufficient edge support under cutting loads. The negative 0° relief increases edge robustness for interrupted or heavy cuts, making the insert suited to tougher operational conditions than positive‑relief types. The DNMG form (rhombic 55°) is a versatile geometry for external turning and facing; its form helps to distribute cutting forces and enables predictable toolpath strategies on lathes and turning centres. These geometric choices translate into fewer setup adjustments and improved repeatability.

Application scenarios and operational benefits

When machining components in stainless steel or heat‑resistant alloys, the insert’s composition and chip control reduce the tendency for edge build‑up and thermal‑induced failures. This supports higher process security and consistent surface quality for serial production. For workshops aiming to increase productivity, the mix of thermal resilience, chip control and geometric robustness reduces downtime and contributes to a more efficient machining flow. The insert is compatible with standard DNMG toolholders and can be integrated into existing tool arrangements without additional special tooling.
