WNMA060412-RK5 WKK10S — indexable turning insert (Trigon 80°) by Walter Tools, Tiger‑tec Silver, RK5

The WNMA060412-RK5 WKK10S is an indexable turning insert engineered for productive machining of cast iron, combining a Tiger‑tec Silver coated carbide grade with a controlled-chip RK5 breaker for consistent performance in demanding turning operations.

• Tiger‑tec Silver coated carbide for long life
• Optimised for cast iron (ISO K) machining
• Trigon 80° form, 1.2 mm corner radius
• RK5 chipbreaker for controlled chip formation

Increased productivity for cast iron with a coated carbide grade

The Tiger‑tec Silver coating provides a wear-resistant surface that supports longer tool life and steady performance when machining abrasive cast iron grades. This coated carbide formulation is tuned to handle the short, brittle chips typical of cast iron, so production runs remain consistent. The result is fewer insert changes and more uptime on lathes and turning centres, which directly improves throughput and lowers process interruptions.

Robust geometry that resists breakage in interrupted cuts

The Trigon 80° insert form with a 1.2 mm corner radius and a 0° negative rake gives a mechanically strong cutting edge well suited to interrupted or heavy cuts. The acute trigonal form supports secure seating in toolholders and allows stable cutting forces, which reduces vibration and the risk of premature edge chipping. This geometry benefits shops seeking dependable performance in short-chipping materials.

Precise chip control for safer, cleaner machining

Equipped with the RK5 chipbreaker, the insert produces reliably formed chips that evacuate predictably from the cutting zone. Controlled chip formation reduces the need for manual intervention and improves operator safety, while also supporting consistent surface finishes. For series production or heavy-duty turning operations, predictable chips mean fewer process halts and simplified downstream handling.

Practical benefits for workshop planning and tool selection

Using a grade selected for cast iron (ISO group K) streamlines tool choice for mixed-shop environments where abrasive grey or nodular cast irons are common. The combination of coating, geometry and chipbreaker means the insert can be specified as the standard solution for cast iron turning tasks, simplifying inventory and making tool management more economical and efficient.
