WNMA060404-RK5 WKK10S — indexable turning insert, Trigon 80° geometry, Tiger‑tec Silver (Walter Tools)

The WNMA060404-RK5 WKK10S is an indexable turning insert engineered for efficient machining of cast‑iron components, combining a Trigon 80° form with a dedicated RK5 chipbreaker for controlled, repeatable chip formation.

• Tiger‑tec Silver coated carbide grade WKK10S
• Optimised for cast‑iron machining
• Trigon 80° geometry with 0.4mm corner radius
• Negative 0° rake for stable cutting

Consistent chip control for uninterrupted production

The RK5 chipbreaker is designed specifically for the short, brittle chips typical of cast‑iron machining. By promoting predictable chip segmentation and evacuation, the insert reduces the risk of chip buildup and tool interference, which leads to fewer interruptions at the machine and more stable cycle times. The combination of Trigon 80° geometry and the RK5 form provides a balance between entry strength and chip formation, helping to maintain process continuity in both roughing and medium finishing operations.

Long tool life through optimised coating and grade

The WKK10S grade, realised via the Tiger‑tec Silver coating technology, addresses the abrasive wear common with grey and nodular cast irons. This coated carbide composition offers improved resistance to flank and crater wear, extending the usable life of the insert under standard industrial cutting conditions. The result is reduced tooling consumption and a lower cost per part in high‑volume turning tasks where abrasive constituents accelerate wear on uncoated grades.

Geometry and mechanical stability for demanding cuts

The Trigon 80° insert form with a 0.4 mm corner radius and a negative 0° rake provides mechanical robustness at the cutting edge, increasing stability during interrupted cuts and heavy cross‑section removal. The geometry supports a secure seat in standard indexable toolholders and helps to maintain dimensional consistency across multiple indexings. This mechanical reliability improves part quality and reduces the need for frequent re‑setups.

Application spectrum and process benefits

Intended primarily for machining cast‑iron (ISO group K), this insert performs well in applications requiring effective chip breaking and wear resistance. The coated grade and RK5 chip control make it suitable for both conventional lathes and CNC turning centres handling engine components, housings, and other cast parts. Choosing this insert supports predictable tool change intervals and contributes to stable surface finish outcomes without complex process adjustments.
