CPMW09T308-RK6 WKK20S indexable turning insert for cast iron, Tiger·tec Silver – Walter Tools

A high-performance CPMW09T308-RK6 WKK20S indexable turning insert optimised for cast iron machining, offering abrasion resistance and reliable chip control in industrial turning operations

• Tiger·tec Silver coating for abrasion resistance
• WKK20S grade optimised for cast iron
• RK6 chipbreaker for consistent chip control
• Rhombic 80° shape with 0.8 mm corner radius

Maximise productivity and reduce tool changes in cast iron turning

The combination of the Tiger·tec Silver coating and the WKK20S grade is engineered to resist the abrasive wear typical of cast iron applications. The coated carbide substrate reduces flank wear and prolongs cutting edge life, which translates into fewer tool changes and higher machine uptime. For production environments where predictable tool life leads directly to lower running costs, this insert supports a stable process and consistent component quality.

Predictable chips and process stability for safer machining

Equipped with the RK6 chipbreaker, the insert produces short, controlled chips suited to cast iron materials, improving handling in automated and manual setups. The rhombic 80° geometry together with an 0.8 mm corner radius and 11° clearance angle offers a robust cutting edge that resists chipping while providing reliable access to varied turning profiles. Better chip control leads to reduced cycle interruptions and a cleaner machining area, supporting higher throughput and improved surface finish.

Practical dimensions and integration into standard toolholders

The insert size (09) and T3 thickness conform to common tooling systems, allowing straightforward integration into existing toolholders without complex adaptations. The cutting material is a coated carbide optimised for abrasive cast iron work, classified under a medium tolerance class for consistent interchangeability. With Walter Tools' manufacturing standards, the component supports repeatable mounting and predictable performance across batches, simplifying inventory and process planning.
