CCMT120408-FK6 WKK10S — Boring/Turning Indexable Insert for Cast Iron (Walter Tools)

CCMT120408-FK6 WKK10S is a coated indexable insert designed for productive turning and boring operations in cast iron components, combining a robust chipformer with the Tiger·tec Silver coating for consistent tool life.

• Tiger·tec Silver coating for wear resistance
• WKK10S grade optimised for cast iron machining
• Rhombic 80° shape for versatile turning and boring
• FK6 chipformer for stable, short chips

High productivity through optimised coating and grade

The combination of the Tiger·tec Silver coating and the WKK10S grade is engineered for abrasive cast iron applications. The coating reduces flank and crater wear, which extends tool life and reduces changeover frequency; the grade is tuned to the short, breaking chips typical of cast iron. This results in measurable productivity gains: longer uninterrupted cutting times and fewer insert replacements, contributing to a smoother production flow and predictable process windows.

Geometry that balances strength and flexibility

The rhombic 80° outline and the 0.8 mm corner radius provide a resilient cutting edge that performs well across a range of turning and boring tasks. The 80° shape offers a compromise between access and edge strength, while the 7° clearance angle maintains a stable cutting contact, reducing rubbing and heat build‑up. Together these geometric choices improve surface finish and make the insert suitable for both roughing and finishing passes where repeatable results are required.

Consistent chip control for safer machining

Equipped with the FK6 chipformer, this insert produces short, controllable chips in cast iron, lowering the risk of entanglement and improving evacuation from the cutting zone. Short chips help to protect the workpiece and the toolholder, support higher metal removal rates and simplify automatic handling. The product is specified to tolerance class M, ensuring consistent dimensions and reliable seating in the toolholder, which is particularly important for high‑precision or automated setups.

Application clarity and selection guidance

The insert is intended primarily for machining cast iron as specified under ISO recommendations for the K group; the construction is coated carbide suited to abrasive materials. For operations requiring different chip behaviour or tougher steels, alternative grades and chipformers should be considered. Technical documentation supplied by Walter Tools clarifies the recommended cutting parameters; for specific process recommendations and to verify suitability for particular cast iron grades, Metav Werkzeuge offers application support and cutting data.

FAQ

What materials is this insert designed for?
The CCMT120408-FK6 WKK10S insert is designed primarily for machining cast iron and is optimised for the abrasive and short‑chip characteristics of those materials.

What is the benefit of the Tiger·tec Silver coating?
The Tiger·tec Silver coating on the CCMT120408-FK6 WKK10S reduces wear and improves thermal stability, extending tool life and maintaining cutting performance in abrasive cast iron applications.

How does the FK6 chipformer affect machining?
The FK6 chipformer promotes short, controllable chips during turning and boring, improving chip evacuation and reducing the risk of entanglement or surface damage.

Is this insert suitable for finishing passes?
Yes; with the rhombic 80° geometry and a 0.8 mm corner radius, the insert can be used for both productive roughing and controlled finishing operations, offering a balance between edge strength and surface quality.

What does tolerance class M indicate?
Tolerance class M denotes medium precision in dimensional tolerances, ensuring consistent seating and repeatable tool offsets in standard toolholders.
