CCGT060204-MK4 WKK20S — Indexable turning insert, Rhombic 80°, for cast iron — Walter Tools

A CCGT060204-MK4 WKK20S indexable turning insert designed to provide productive, wear‑resistant performance when machining cast iron components.

• Tiger‑tec Silver coating for long tool life
• Optimised MK4 chipbreaker for cast iron
• Rhombic 80° form for stable cutting
• 7° clearance with 0.4 mm corner radius

Durable coating and grade for higher productivity

The combination of the Tiger‑tec Silver coating and the WKK20S grade creates a coated carbide surface engineered to resist abrasive wear typical of grey irons. This performance focus reduces flank wear and prolongs service intervals, which translates into fewer insert changes and improved uptime on turning centres. For production environments that demand predictable tool life and repeatable results, the advanced coating technology supports higher cutting speeds and stable tool behaviour under interrupted or continuous cuts.

Geometry and chip control that stabilise processes

The MK4 chipbreaker and Rhombic 80° plate shape deliver controlled chip formation and secure cutting engagement. A 7° clearance angle improves cutting edge clearance, while the 0.4 mm corner radius balances edge strength and surface finish. For operators unfamiliar with technical terms: the chipbreaker grooves promote short, controllable chips for cast iron, reducing the risk of entanglement and supporting safer, more efficient material removal. The insert geometry also aids in maintaining consistent part tolerances across production runs.

Application focus and process security for cast iron work

Specified for the ISO group K, this insert is tuned for machining cast iron where fractures and abrasive particles demand robust cutting edges. The insert construction and tolerance class G ensure reliable seating and repeatable indexing in compatible tool holders, contributing to stable machining cycles and consistent workpiece quality. Backed by the Walter Tools product family, the design emphasises dependable performance and predictable maintenance planning for industrial turning operations.

FAQ

Which materials is this insert optimised for?
The CCGT060204-MK4 WKK20S insert is optimised for machining cast iron (ISO group K) and is tuned to handle the abrasive wear and short, brittle chips typical of those materials.

How does the Tiger‑tec Silver coating benefit production?
Tiger‑tec Silver coating on the WKK20S grade enhances wear resistance and thermal stability, allowing higher cutting speeds and longer tool life compared with uncoated grades.

What advantages does the MK4 chipbreaker provide?
The MK4 chipbreaker promotes short, controllable chips when turning cast iron, improving chip evacuation and reducing the likelihood of chip-related interruptions during machining.

Is the Rhombic 80° form suitable for interrupted cuts?
Yes, the Rhombic 80° shape offers stable clamping and multiple effective cutting edges, making it well suited to operations that include intermittent engagement or varying depths of cut.

How should the corner radius be considered when selecting cutting parameters?
The 0.4 mm corner radius balances edge strength and surface finish; smaller depths of cut favour finer finishes while larger engagements benefit from the added robustness of the radius.
