CNMG190616-MK5 WKK10S — Turning insert for cast iron | Walter Tools

A CNMG190616-MK5 WKK10S indexable turning insert designed for productive cast iron machining with the Tiger·tec Silver coating and an MK5 chipbreaker.

• Tiger·tec Silver coating for wear resistance
• Optimised for cast iron (ISO group K)
• Rhombic 80° geometry, 1.6 mm corner radius
• MK5 chipbreaker for controlled chip formation

Increase cutting performance and reduce downtime

The coated cemented carbide combination of Tiger·tec Silver and WKK10S focuses on abrasion resistance and reliable edge stability when turning cast iron. This composition reduces flank wear under interrupted cuts and high abrasive loads, which translates into longer tool life and fewer insert changes. The organised interaction between coating and substrate enables consistent dimensional results and supports higher metal removal rates without sacrificing surface quality.

Achieve safer, more predictable chip control

The integrated MK5 chipbreaker has been engineered to manage short, breaking chips typical of cast iron machining, improving evacuation and reducing built-up edge. The negative 0° relief and Rhombic 80° form increase cutting edge strength, while the 1.6 mm corner radius balances durability with accessibility in many turning profiles. Together these features provide a predictable cutting process, minimising unplanned stoppages and enhancing workplace safety.

Practical compatibility and efficiency in production

With the CNMG190616-MK5 WKK10S insert, workshops benefit from a straightforward technical fit into standard toolholders for rhombic inserts and from a clear materials focus: optimised for the ISO group K. This simplifies grade selection and reduces trial-and-error on new jobs. If additional machining data or suitability checks are required, Metav Werkzeuge provides application consulting and fast technical responses to support integration into existing processes.
