CCMT120404-RK4 WKK10S – Indexable insert for boring and turning, cast iron, Walter Tools

The CCMT120404‑RK4 WKK10S is a rhombic insert designed for efficient machining of cast iron components in demanding production environments.

• Tiger‑tec Silver coating for extended life
• WKK10S grade optimised for cast iron
• RK4 chipbreaker for short, controllable chips
• Rhombic 80° geometry for flexible cutting

Consistent performance on abrasive cast iron

The combination of the Tiger‑tec Silver coating and the WKK10S substrate delivers high wear resistance specifically tuned for the abrasive nature of cast iron. Coated carbide provides a protective layer that reduces flank wear and thermal damage during interrupted cuts. For production shops, this means fewer insert changes and a steadier process window, leading to improved process reliability and predictable part quality.

Geometry tailored for chip control and edge stability

The rhombic 80° form together with the RK4 chipbreaker and a 0.4 mm corner radius produces short, repeatable chips that evacuate reliably from the cutting zone. The 7° clearance angle reduces rubbing while maintaining a robust cutting edge. These geometric choices lower the risk of built‑up edge and support consistent surface finishes, particularly in turning and boring operations where chip behaviour and edge strength determine productivity.

Practical benefits for workshop productivity

As an indexable insert, the CCMT120404‑RK4 WKK10S simplifies tool management: a single insert type covers a range of turning and boring tasks on cast iron, reducing inventory complexity. Improved tool life and controlled chip formation translate directly to fewer interruptions and higher throughput. For operations aiming to balance tooling cost and cycle time, this insert provides a measurable advantage in overall equipment effectiveness.

FAQ

Is this insert suitable for machining cast iron?
Yes. The CCMT120404‑RK4 WKK10S is specifically optimised for cast iron, with a coated carbide grade and chipbreaker designed for abrasive, short‑chipping materials.

Can the insert be used in both turning and boring operations?
The rhombic 80° geometry and robust chip control make the insert suitable for a variety of turning and boring tasks where cast iron is the workpiece material.

What are the key advantages of the Tiger‑tec Silver series for this grade?
The Tiger‑tec Silver coating enhances wear resistance and thermal stability, which helps to extend the service life of the insert under interrupted cuts and abrasive conditions typical of cast iron machining.

How does the RK4 chipbreaker influence productivity?
The RK4 chipbreaker produces short, controllable chips that evacuate easily, reducing downtime from chip issues and improving process stability during continuous production.

Is the corner radius specified important for surface finish?
Yes. The 0.4 mm corner radius contributes to edge strength and affects the achievable surface finish and dimensional stability during finish‑oriented turning passes.
