CCMW120412-RK6 WKK20S indexable turning insert – Tiger·tec Silver, for cast iron machining (Walter Tools)

CCMW120412-RK6 WKK20S is a rhombic 80° indexable turning insert designed for productive machining of cast iron with a robust RK6 chipbreaker and Tiger·tec Silver coating.

• Tiger·tec Silver coating for wear resistance
• Optimised for cast iron machining
• RK6 chipbreaker for controlled chips
• Rhombic 80° geometry for universal turning

Durable coating and material pairing for longer tool life

The coated cemented‑carbide grade WKK20S, part of the Tiger·tec Silver series, is formulated to resist the abrasive wear typical of cast‑iron workpieces. This combination reduces flank wear and extends effective tool life under interrupted and continuous cuts. For production environments the result is fewer index changes and less unplanned downtime, which supports predictable machining cycles and improves overall process economy.

Geometry and chip control that stabilise the cutting process

The insert’s RK6 chipbreaker, together with the rhombic 80° cutting geometry and a corner radius of 1.2 mm, provides stable cutting and repeatable chip formation when machining cast iron. The specified 7° clearance angle helps avoid rubbing while maintaining adequate edge support. These design choices translate into consistent surface finish and reliable chip evacuation, reducing the need for manual intervention during turning operations.

Integration into the production flow and performance benefits

As an indexable turning insert, this component enables fast re‑indexing and predictable performance across tool changes. The combination of a purpose‑matched grade and controlled chipbreaking improves cut stability and often allows higher material removal rates compared with non‑optimised grades. For workshops aiming to raise throughput, this insert contributes to steady manufacturing output and reduced overall tooling costs per part without sacrificing surface quality.

FAQ

Is this insert suitable for cast iron?
Yes. The CCMW120412‑RK6 WKK20S insert by Walter Tools is specifically formulated for cast‑iron machining and is designated for material group K.

What advantages does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating on the WKK20S grade improves abrasive wear resistance and supports longer, more consistent tool life in cast‑iron applications.

What is the function of the RK6 chipbreaker?
The RK6 chipbreaker controls chip shape and evacuation during turning, aiding in stable cutting and reducing interruptions from poor chip formation.

Which operations suit the rhombic 80° geometry?
Rhombic 80° geometry is versatile for general turning tasks, offering good access to shoulders and allowing a wide range of cutting angles for effective material removal.

How is edge strength balanced against surface finish?
With a 1.2 mm corner radius and 7° clearance, the insert balances edge support and cutting sensitivity to achieve reliable surface finish while maintaining robustness.
