CCMT060204-RK4 WKK10S indexable turning insert with Tiger‑tec Silver, for cast iron — Walter Tools

The CCMT060204-RK4 WKK10S is a rhombic 80° indexable insert designed for productive turning of cast iron, combining a coated carbide grade with a dedicated chipbreaker for controlled, repeatable machining.

• Tiger‑tec Silver coating for high wear resistance
• Optimised for cast iron (ISO K)
• Rhombic 80° geometry for versatile cutting angles
• 0.4 mm corner radius, 7° clearance for stable cuts

Increased productivity through optimised coating and grade

The combination of the Tiger‑tec Silver coating with the WKK10S grade is engineered for abrasive cast iron applications. The coated carbide provides improved wear resistance and extended tool life, which directly reduces tool change frequency and downtime. The insert’s chipbreaker RK4 is tailored to the typically short, brittle chips of cast iron, promoting consistent chip segmentation and safe evacuation. This results in a measurable increase in machining efficiency and predictable cycle times. For production environments, the technical choice of a coating‑grade pair tuned to the workpiece material translates into lower running costs and higher throughput.

Precision and process reliability from geometry and tolerance

A rhombic 80° insert form offers a robust seating and versatile cutting edge orientation for a variety of turning operations. The 0.4 mm corner radius and 7° clearance deliver a balance between edge strength and surface finish: the radius supports a stable cutting edge under intermittent loads, while the clearance minimises rubbing. The insert is supplied in tolerance class M, ensuring repeatable location and consistent cutting behaviour across indexed positions. Those aspects reduce set‑up variability and support reliable surface quality in series production, making the component well suited for demanding cast iron turning tasks where consistency matters.

Practical advantages and support for shopfloor decisions

Choosing this insert provides a clear operational benefit: controlled chip formation, improved tool life and straightforward indexability. The insert form and chip control reduce the risk of chip jamming and protect downstream equipment. For users less familiar with tooling specifics, the terminology means the following in practice: a coated carbide insert (Tiger‑tec Silver) resists abrasive wear common with cast iron; RK4 denotes the chipbreaker style tuned to produce short, manageable chips; the rhombic 80° shape allows flexible toolholder set‑up. If additional machining data or optimisation tips are required, Metav Werkzeuge’s technical advisers are available to assist with feed and speed recommendations tailored to specific cast iron grades.
