DNMG150612-MW5 WKK20S indexable turning insert — Tiger‑tec Silver coating, for cast iron, Walter Tools

The DNMG150612-MW5 WKK20S is an indexable turning insert designed for productive finishing and medium-duty roughing of cast‑iron components.

• Tiger‑tec Silver coating for abrasive conditions
• Optimised MW5 chipbreaker for controlled chips
• Rhombic 55° geometry for versatile turning
• Corner radius 1.2 mm for edge stability

Optimised performance for cast‑iron turning

The combination of Tiger‑tec Silver technology and the WKK20S grade delivers increased wear resistance when machining cast iron, where abrasive wear and short, breakable chips are common. The coated carbide substrate provides a predictable tool life and helps maintain dimensional consistency over extended runs. The insert’s profile and coating are tuned to reduce flank wear, resulting in fewer tool changes and improved uptime on the lathe.

Predictable chip control and surface quality

Equipped with an MW5 chipbreaker, the geometry produces short, manageable chips that reduce downtime and improve operator safety. The rhombic 55° form permits a range of turning operations with stable engagement, while the 0° negative clearance enhances cutting edge strength for interrupted cuts. Together these features support a reliable machining process and help achieve consistent surface finish with minimal rework.

Robust edge life and process reliability

The 1.2 mm corner radius provides mechanical strength at the cutting edge, lowering the risk of chipping under variable loads and extending insert life in medium‑to‑high wear situations. This results in fewer indexings per component and a steadier production flow. For production environments requiring repeatable results, the insert’s tolerance class M and stable geometry contribute to reproducible part quality.

Practical fitment and series benefits

Belonging to the Tiger‑tec Silver series, the insert is manufactured to industrial standards for interchangeability and process integration. The DNMG150612-MW5 form factor fits many standard toolholders specified for rhombic 55° turning inserts and is particularly suitable where cast‑iron machinability dictates a specialised grade. The controlled combination of substrate, coating and chipbreaker supports both finishing and general turning tasks.

FAQ

Which materials is this insert intended for?
The DNMG150612-MW5 WKK20S from Walter Tools is optimised for cast iron machining (material group K), where its grade and coating counter abrasive wear and handle short, breaking chips.

What advantage does the Tiger‑tec Silver coating offer?
Tiger‑tec Silver increases abrasion resistance and thermal stability on the cutting edge, so the Walter Tools insert sustains performance longer under abrasive cast‑iron conditions.

How does the MW5 chipbreaker affect machining?
The MW5 chipbreaker ensures controlled, short chips that simplify chip evacuation and reduce entanglement, improving process reliability and operator safety during turning.

Is the insert suitable for interrupted cuts?
The combination of a 0° negative clearance and a 1.2 mm corner radius gives the insert robust edge strength, making it appropriate for intermittent engagement and variable cutting conditions.

What toolholders are compatible with this insert form?
The DNMG150612-MW5 form factor is compatible with standard holders designed for rhombic 55° inserts; consult Metav Werkzeuge for confirmed holder recommendations and clamping systems.
