VCMT160404-RK4 WKK10S Walter Tools — indexable turning insert, Tiger‑tec Silver coating, for cast iron

A VCMT160404-RK4 WKK10S indexable turning insert engineered for productive cast iron machining, combining a robust coated carbide grade with a controlled chipbreaker and a compact rhombic 35° form.

• Tiger‑tec Silver coating for extended tool life
• Optimised for cast iron (ISO group K)
• Rhombic 35° form with 0.4 mm corner radius
• RK4 chipbreaker for controlled chip formation

Extend productive cutting time and reduce interventions

The combination of the Tiger‑tec Silver coating and a coated carbide grade provides significantly improved resistance against abrasive wear typical for cast iron applications. By reducing flank and crater wear, this insert extends tool life, which in turn reduces changeover frequency and contributes to more predictable cycle times. The insert’s design targets the short, brittle chips produced when machining grey and ductile cast irons, so process stability is improved without sacrificing productivity. For operations where run-time and repeatability matter, the robust coating technology supports continuous production with fewer unplanned interruptions.

Achieve consistent chip control and surface quality

Built with an RK4 chipbreaker and a rhombic 35° geometry, the insert promotes reliable chip formation and evacuation. The moderate approach angle inherent to the rhombic form balances cutting forces and allows for dependable removal of short cast-iron chips, helping to protect both the workpiece and the tool holder. The 0.4 mm corner radius supports edge strength and contributes to a stable cutting edge that maintains surface finish across extended tool lives. This geometry is particularly advantageous in finishing and semi-finishing passes where repeatable dimensional results and consistent roughness are required.

Grade and application focus for dependable cast iron machining

The WKK10S grade, part of the Tiger‑tec Silver series, is specifically tuned for ISO group K — cast iron — addressing the abrasive wear and fracturing chip behaviour typical of these materials. The insert’s format and cutting-edge specifications make it a suitable choice for a range of turning tasks from profile turning to shoulder cuts where cast iron is the primary workpiece material. The compact design ensures compatibility with standard VCMT tool holders and enables flexible setup in automated turning centres. Operators and process engineers benefit from a balanced solution that prioritises stability, reproducibility and efficiency in cast-iron production environments.
