WNMA100612-RK5 WKK10S – Trigon 80° turning insert by Walter Tools (Tiger·tec Silver, for cast iron)

The WNMA100612-RK5 WKK10S is a trigon 80° turning insert designed for efficient machining of cast iron components with a coated carbide grade optimised for abrasive wear and short, breaking chips.

• Tiger·tec Silver coating
• Optimised for cast iron (ISO K)
• Trigon 80° geometry
• Robust RK5 chipbreaker

Increased throughput through targeted wear resistance

The combination of the Tiger·tec Silver coating and the WKK10S grade delivers higher tool life when machining abrasive grey and nodular cast iron. The advanced coating technology reduces flank wear and extends the productive life of the insert, which leads to fewer tool changes and improved machine uptime. For production environments where cycle time and repeatability matter, this turning insert supports a more economical process by maintaining cutting performance over longer tool intervals.

Predictable chip control and surface consistency

The RK5 chipbreaker and Trigon 80° geometry were developed for controlled chip formation in interrupted and continuous cutting of cast iron. The controlled chip flow reduces the risk of built-up edge and improves surface finish consistency. Operators with limited experience in insert selection benefit from the stable behaviour of this geometry, since the chipbreaker is tuned to transform brittle cast-iron chips into easily manageable segments, lowering the workload at the machine and on downstream handling.

Robust geometry for secure clamping and reproducible results

The insert’s corner radius of 1.2 mm and negative 0° clearance are engineered to provide a strong cutting edge and predictable cutting forces, which helps maintain dimensional accuracy across serial production. The trigon shape gives multiple cutting edges per insert, reducing tooling costs per component and enabling quick index changes. Combined with the coated carbide substrate, the design supports reliable performance where abrasive wear is the principal limitation.

FAQ

Is this insert suitable for all types of cast iron?
The WNMA100612-RK5 WKK10S insert by Walter Tools is optimised for ISO group K and performs well on common cast-iron grades, offering reliable chip control and wear resistance for typical cast-iron turning operations.

Can the insert be used for stainless steel or hardened materials?
This insert is designed specifically for cast iron (ISO K). It is not recommended for stainless steel or significantly hardened steels; alternative grades and coatings are available for those applications.

How does the RK5 chipbreaker help in interrupted cuts?
The RK5 chipbreaker promotes short, manageable chips and stabilises cutting forces, which improves performance in interrupted cuts commonly encountered with cast-iron workpieces when using the WKK10S grade.

What advantage does the Trigon 80° shape provide?
The trigon 80° form offers multiple cutting edges per insert and a robust edge geometry, supporting economical indexing and consistent results in serial production.

Is the WKK10S grade suitable for high-production environments?
Yes; the wear-resistant WKK10S grade with Tiger·tec Silver coating is engineered for productivity and stable wear behaviour in cast-iron machining, making it well suited to high-production settings.
