CCMT060208-MK4 WKK20S — Turning/Boring Insert for Cast Iron — Walter Tools

The CCMT060208-MK4 WKK20S is a rhombic 80° indexable insert designed for productive turning and boring of cast iron components with optimised chip control and wear resistance.

• CCMT060208-MK4 WKK20S insert by Walter Tools
• Tiger‑tec Silver coating for high wear resistance
• Optimised MK4 chipbreaker for cast iron chips
• Rhombic 80° form, 0.8 mm nose radius

Increased tool life through optimised coating and grade

The combination of Tiger‑tec Silver coating and the WKK20S grade provides enhanced resistance against the abrasive wear typical of cast iron machining. This coated carbide formulation is tailored for the short, breaking chips and abrasive particles found in grey and nodular cast irons, leading to a more stable cutting edge and extended indexable-insert life. Fewer tool changes reduce machine downtime and contribute directly to lower production costs per component.

Predictable chip control for uninterrupted production

An MK4 chipbreaker specifically adapted to cast iron promotes immediate chip fragmentation and reliable evacuation. The result is reduced risk of chip entanglement, fewer surface blemishes and less operator intervention during long turning cycles. With consistent chip behaviour, process parameters can be standardised, increasing reproducibility across batches and supporting higher throughput without compromising surface integrity.

Geometry designed for finish and strength

The rhombic 80° form paired with a 0.8 mm corner radius balances profile accuracy and cutting-edge robustness. The moderate nose radius improves surface finish while maintaining strength at the cutting edge, making the insert suitable for a range of turning operations from semi-finishing to finishing. A relief angle of 7° ensures good contact geometry with many common toolholders, supporting steady cutting forces and minimised chatter on medium- to heavy-duty lathe work.

Practical integration into machining workflows

As a standard CCMT insert, the component fits commonly used toolholders, simplifying inventory and changeover. The plate thickness and size ensure mechanical stability under typical cast iron cutting conditions. Given its design focus, the insert is particularly suited to production environments and job shops machining cast iron where predictable performance and long runtimes matter.

FAQ

What materials is this insert intended for?
The CCMT060208-MK4 WKK20S insert and its WKK20S grade are engineered for cast iron machining and perform well with the abrasive wear and short, breaking chips typical of that material.

How does the MK4 chipbreaker improve machining?
The MK4 chipbreaker promotes reliable fragmentation of cast iron chips, reducing entanglement and improving surface quality, which helps maintain uninterrupted production runs.

What effect does the 0.8 mm nose radius have on finish and strength?
A 0.8 mm corner radius provides a practical balance between edge strength and surface finish, allowing for controlled cutting forces during semi-finish and finish turning operations.

Is the rhombic 80° geometry widely compatible with holders?
The rhombic 80° form is a standard geometry for many CCMT-style toolholders; verification of specific holder compatibility is recommended before mounting.

How does the Tiger‑tec Silver coating benefit shop-floor processes?
The Tiger‑tec Silver coating enhances wear resistance and thermal stability, extending tool life under the abrasive conditions encountered when turning cast iron.
