CCMW120408-RK6 WKK20S indexable turning insert, RK6 chipbreaker, for cast iron — Walter Tools

The CCMW120408-RK6 WKK20S is an indexable turning insert designed for productive cast iron machining, featuring the Tiger·tec Silver coating and a compact 0.8 mm corner radius for stable finishing and roughing tasks

• Tiger·tec Silver coated for high wear resistance
• Optimised for cast iron machining (ISO group K)
• Rhombic 80° geometry with 0.8 mm corner radius
• RK6 chipbreaker for stable chip control

Longer tool life through advanced coating and grade selection

The combination of a Tiger·tec Silver coating and a coated carbide substrate results in markedly improved wear resistance, which extends tool life and reduces changeover frequency. The applied coating technology is engineered to withstand the abrasive nature of cast iron, so cutting intervals are extended and process interruptions are minimised. This yields a clear economic advantage by reducing tool consumption per workpiece while maintaining consistent surface quality.

Geometry and chip control that support consistent production

The Rhombic 80° shape delivers positive engagement and good edge support, while the 0.8 mm corner radius balances strength and surface finish. The RK6 chipbreaker is tailored to the typical short, brittle chips produced when machining cast iron, promoting predictable chip formation and evacuation. These geometric features enable higher productivity through reliable cutting forces and reduced risk of chip re-cutting, which helps maintain cycle times and machine uptime.

Application focus and process reliability for cast iron components

Engineered specifically for ISO group K materials, this insert is suited to common cast iron applications where abrasive wear and intermittent chip breakage are typical challenges. Because the grade is matched to the material, the insert provides reproducible performance across batch production and one‑off jobs alike. The resulting process reliability supports planning certainty and contributes to stable manufacturing output with fewer corrective interventions.
