CNMG160616-RP5 WKK20S indexable turning insert for cast iron, Rhombic 80° — Walter Tools

A CNMG160616-RP5 WKK20S indexable insert engineered for efficient machining of cast iron components, offering Tiger‑tec Silver coating and RP5 chip control for stable, productive turning.

• Tiger‑tec Silver coating for wear resistance
• Grade WKK20S tuned for cast iron
• Rhombic 80° form for stable cutting
• RP5 chipbreaker for controlled chips

High productivity through tailored coating and grade

The combination of the Tiger‑tec Silver coating and the WKK20S carbide grade delivers superior wear resistance specifically for abrasive cast‑iron applications. The coating reduces flank wear and thermal loading, which in turn stabilises cutting performance and extends tool life. For production environments that require consistent cycle times, this insert reduces the frequency of index changes and supports a smoother machining process. The RP5 chipbreaker is optimised to handle the typically short, brittle chips from cast iron, improving evacuation and reducing the risk of recutting while maintaining dimensional stability.

Robust geometry for repeatable dimensional accuracy

The rhombic 80° shape combined with a 1.6 mm corner radius and a 0° negative clearance provides a balance between edge strength and access to tight contours. The geometry supports reliable edge retention under interrupted cuts and helps maintain surface finish when moderately aggressive feeds are applied. With tolerance class M and execution G, the insert ensures predictable seating in toolholders and repeatable positioning, which is vital for batch production and multi‑station setups. The result is fewer regrinds, less scrap and improved process security.

Application guidance and process integration

Designed for the ISO group K (cast iron), this insert is suitable for a wide range of cast‑iron grades and turnover tasks that demand steady productivity. The series provides good chip control and long‑term stability, making it a practical choice for both single‑piece flow and volume turning. For integration into existing tool systems, match the CNMG seat and clamping to standard toolholders for rhombic inserts; fine‑tune feeds to favour chip formation with the RP5 breaker and adjust cutting speeds upwards within the limits of machine rigidity and coolant strategy to benefit from Tiger‑tec Silver's thermal protection. For specific cutting data and holder recommendations, consult the supplier for tailored parameters.

FAQ

Which materials is this insert designed for?
The CNMG160616-RP5 WKK20S insert from Walter Tools is optimised for cast iron (ISO group K) and performs reliably on abrasive grey and nodular cast‑iron grades.

What advantage does the Tiger‑tec Silver coating provide?
Tiger‑tec Silver on the WKK20S grade improves heat resistance and reduces flank wear, enabling longer tool life and more consistent performance during cast‑iron turning.

How does the RP5 chipbreaker affect machining?
The RP5 chipbreaker promotes short, manageable chips in cast‑iron applications, enhancing evacuation and reducing the risk of chip entanglement when using the CNMG160616-RP5 WKK20S insert.

What does the rhombic 80° form mean for cutting strategy?
The rhombic 80° geometry offers a robust cutting edge and good approach angles for turning operations, supporting stable cuts and accessible tool paths for typical cast‑iron components.
