DCMT11T308-RK4 WKK10S – Indexable turning insert, Rhombus 55°, for cast iron · Walter Tools

DCMT11T308-RK4 WKK10S is a coated carbide indexable insert engineered for productive turning of cast iron components in industrial metal‑cutting operations

• High wear resistance with Tiger‑tec Silver
• Optimised RK4 chipbreaker for cast iron
• Rhombic 55° geometry for flexible turning
• 0.8 mm corner radius for robust edge stability

Consistent machining performance for cast iron components

The insert delivers predictable performance on abrasive cast iron thanks to the Tiger‑tec Silver coating and the WKK10S carbide grade. The coating improves resistance to abrasive wear while the grade balances toughness and edge retention, resulting in longer service intervals and fewer index changes. With the RK4 chipbreaker, the insert controls short, brittle chips typical of cast iron, reducing interruptions and improving process stability. This leads to higher machine utilisation and a smoother production flow for series and batch turning operations.

Geometry engineered for dimensional reliability and surface quality

A rhombic 55° insert geometry combined with a 7° clearance angle and a 0.8 mm corner radius provides a strong, reliable cutting edge that tolerates interruptions and deflections. The combination of geometry and edge preparation supports consistent component tolerances and an improved surface finish under varying cutting conditions. The tolerance class M ensures reproducible form and fit when using standard toolholders, making the insert suitable for repeatable production processes and tool management systems.

Practical process advantages and integration into tooling systems

Specified as a coated carbide insert from the Tiger‑tec Silver series, the design focuses on abrasion resistance and efficient chip control when machining cast iron. The insert thickness T3 and plate size code 11 suit common toolholder interfaces and make replacement straightforward within established tooling inventories. As an indexable solution, the insert reduces tooling cost per part compared with solid‑carbide alternatives and simplifies on‑machine reversal of cutting edges, supporting both economical and flexible manufacturing. For engineers and process planners, the insert represents a balance of life, performance and predictable behaviour in demanding cast iron applications.
