CCMW09T304-RK6 WKK20S indexable insert for cast iron machining – Walter Tools

A CCMW09T304-RK6 WKK20S rhombic 80° indexable insert engineered for efficient machining of cast iron, combining a Tiger·tec Silver coating with an RK6 chipbreaker for reliable chip control.

• Tiger·tec Silver coating for high wear resistance
• WKK20S grade optimised for cast iron machining
• RK6 chipbreaker for short, controlled chips
• Rhombus 80° shape with 0.4 mm corner radius

Higher productivity through optimised coating and grade

The coated cemented carbide of the WKK20S grade, built on Walter Tools' Tiger·tec Silver technology, is designed to withstand the abrasive wear typical of cast iron. The result is a longer cutting edge life and fewer index changes, which translates directly into improved machine uptime and lower tooling costs per component. The RK6 chipbreaker stabilises chip formation in interrupted and continuous cuts, contributing to repeatable process windows and a consistent surface finish.

Reliable chip control and better surface quality

The combination of the RK6 chipbreaker and the rhombic 80° geometry provides controlled fracture of short chips common with cast iron, reducing the risk of built-up edge and machine interruptions. The 0.4 mm corner radius allows a balance between edge strength and fine finish, making the insert suitable for both semi-finishing and finishing passes on grey and ductile cast irons. Specification and ISO grouping for cast iron (K) mean the insert is matched to the material’s characteristic brittle chip form and abrasive tendencies.

Straightforward integration and flexible application

The CCMW09T304-RK6 form conforms to standard indexable insert interfaces and is available in a T3 thickness with a 7° clearance angle to suit a wide range of toolholders. This standardisation simplifies inventory and tool-change procedures while enabling fast adaptation across turning operations. Technical data such as the rhombus 80° shape and RK6 chipbreaker support predictable regrinding intervals and make the insert a pragmatic choice for batch and series production where consistency and productivity are priorities.

FAQ

What materials is this insert designed for?
The CCMW09T304-RK6 WKK20S insert is designed for machining cast iron (ISO group K) and is optimised for the abrasive wear and short-chip behaviour of those materials.

How does the RK6 chipbreaker affect machining?
The RK6 chipbreaker on the CCMW09T304-RK6 promotes the formation of short, controlled chips, improving process reliability and reducing interruptions during cast iron turning.

Can this insert be used for both finishing and semi-finishing?
Yes, the rhombus 80° geometry with a 0.4 mm corner radius enables both semi-finishing and finishing operations, delivering a compromise between edge strength and surface quality.

Is the Tiger·tec Silver coating beneficial for productivity?
The Tiger·tec Silver coating extends edge life under abrasive conditions typical of cast iron, thereby reducing tool changes and increasing overall productivity when using the CCMW09T304-RK6 WKK20S.

Which tolerance class does the insert conform to?
This indexable insert conforms to tolerance class M, providing consistent geometric accuracy for reliable seating in toolholders.
