WNMA080408-RK5 WKK10S indexable turning insert — Trigon 80°, RK5 chipbreaker by Walter Tools

The WNMA080408-RK5 WKK10S is an indexable turning insert designed for machining cast iron, combining a Trigon 80° shape with a 0.8 mm corner radius for robust edge strength and repeatable results

• Tiger·tec Silver coating for wear resistance
• Optimised for cast iron machining
• Trigon 80° geometry for stable cutting
• 0.8 mm corner radius for precise edge

Consistent machining performance through advanced coating technology

The Tiger·tec Silver coating together with the WKK10S grade is engineered for the abrasive wear typical of cast iron. This pairing improves resistance to flank and crater wear, which extends effective tool life and reduces frequency of indexable-insert changes. As a result, cycle times remain stable over longer production runs and tool-change downtime is reduced, supporting a more continuous manufacturing flow.

Geometry and chip control that stabilise turning operations

The Trigon 80° form with the RK5 chipbreaker is designed to deliver consistent chip formation when machining brittle cast-iron microstructures. The 0.8 mm corner radius increases edge robustness, while the 0° (negative) relief aids in interrupted and heavy-duty cuts by providing a stronger cutting edge. These geometrical features lead to improved surface finish and lower risk of edge chipping under fluctuating loads.

Reliable grade and execution for predictable tool life

The WKK10S coated carbide grade offers a balance between wear resistance and toughness suitable for the ISO group K. The insert’s execution A and tolerance class M ensure dimensional stability and interchangeability in production environments, contributing to process reliability. Using a grade tuned for cast iron lowers scrap rates and supports consistent workpiece tolerances across batches.

Practical integration into production and machining planning

As an indexable insert, this product fits standard toolholders matching the WNMA geometry and allows fast index changes to restore cutting performance. Its focus on cast-iron applications means selection of cutting data should favour chip breakage and moderate cutting speeds appropriate for the workpiece grade. For straightforward implementation, confirm holder compatibility and check recommended machining parameters from production datasheets before machining.
