DNMG150408-MK5 WKK10S — Indexable turning insert, Rhombus 55°, 0.8 mm corner radius (Walter Tools)

A DNMG150408-MK5 WKK10S indexable insert engineered for high-performance turning of cast iron components in industrial production environments.

• Tiger·tec Silver coating for abrasion resistance
• Optimised MK5 chipbreaker for short chips
• Rhombus 55° geometry for versatile turning
• 0.8 mm corner radius for stable edge life

Consistent performance for cast iron machining

The coated carbide grade WKK10S in the Tiger·tec Silver family is tuned specifically for abrasive cast iron applications. Its microstructure and multilayer coating increase abrasion resistance, reducing flank wear on interrupted and continuous cuts and thus extending productive tool life. As a result, operators benefit from fewer index changes and more consistent part quality over long production runs.

Geometry and chip control that keep production running

The Rhombus 55° plate form combined with an MK5 chipbreaker and a 0° (negative) relief angle provides reliable chip formation for brittle, short-chipping materials. The geometry supports stable contact with the workpiece, while the chipbreaker promotes controlled, small chips that improve process security and reduce the risk of tool or workpiece damage. This contributes directly to shorter cycle times and more predictable machining.

Durable edge life and economical tool usage

A 0.8 mm corner radius and the coated carbide substrate deliver a balance between robustness and fine surface finish. The insert’s design reduces the frequency of tool changes and supports consistent edge strength under varying cutting conditions. Reduced downtime and reliable repeatability make the insert a cost-effective choice for medium- to high-volume turning of cast iron components.

Integration into production and application notes

This insert is intended for ISO group K (cast iron) applications and fits standard indexable turning toolholders that accept DNMG-style plates. The MK5 chipbreaker is particularly effective where short, fragmented chips are desired. For optimal results, pair the insert with cutting parameters recommended for cast iron and consult Metav Werkzeuge for tailored speeds and feeds based on machine rigidity and part geometry.
