CCGT060208‑MK4 WKK20S — Rhombic 80° turning/boring insert, Tiger‑tec Silver by Walter Tools

CCGT060208‑MK4 WKK20S is a rhombic 80° insert engineered for machining cast iron under demanding industrial conditions

• Tiger‑tec Silver coating for long tool life
• WKK20S grade optimised for cast iron
• Rhombic 80° geometry for versatile turning/boring
• MK4 chipbreaker for controlled chip formation

Optimised for abrasive cast‑iron machining

The insert is manufactured from coated carbide according to the WKK20S specification and benefits from the Tiger‑tec Silver coating technology. This combination is tailored to the high abrasive wear and the frequently short, brittle chips encountered when machining cast iron. The rhombic 80° form and a corner radius of 0.8 mm balance edge strength and dimensional control, helping to maintain consistent tolerances and surface integrity over longer tool life. The chipbreaker MK4 actively shapes and breaks chips for reduced evacuation issues, which translates into fewer interruptions and a steadier metal‑removal rate on production lines.

Consistent chip control that raises productivity

Stable chip formation, made possible by the integrated MK4 chipbreaker, reduces the risk of built‑up edge and improves process reliability. A clearance angle of 7° ensures effective cutting geometry while limiting flank contact, preserving the cutting edge and improving surface finish on critical components. Compared with generic grades, this grade and coating combination offers a pragmatic balance between wear resistance and toughness, yielding repeatable results and increased productivity in batch machining. For operations seeking predictable performance and lower tool‑change frequency, the insert’s design supports cost‑efficient throughput without compromising component quality.

Easy integration into existing tooling systems and practical benefits

The insert designation CCGT060208‑MK4 WKK20S identifies size, chipbreaker and grade to simplify tool planning and inventory management. The rhombic 80° geometry fits widely used holders for both turning and boring tasks, enabling straightforward integration into established tool‑holders and turret systems. The coated carbide composition and the specified tolerance class (G) support stable machining parameters and reduce trial‑and‑error during process set‑up. For supplementary cutting data or holder recommendations, Metav Werkzeuge can provide application‑specific advice and documented starting values suitable for shop‑floor implementation.

FAQ

What materials is the insert suitable for machining?
The insert is designed primarily for cast iron machining (ISO group K); the WKK20S grade and Tiger‑tec Silver coating are optimised for abrasive, short‑chip cast materials.

How does the MK4 chipbreaker improve production?
The MK4 chipbreaker controls chip formation and assists in producing short, manageable chips, which reduces evacuation issues and machine stops during continuous turning and boring.

What are the key geometry values that affect performance?
The insert features a rhombic 80° shape, a 7° clearance angle and a 0.8 mm corner radius; these parameters support edge strength, effective cutting action and consistent surface quality.

Can the insert be used in standard CCGT holders?
Yes, the CCGT form is compatible with widely used turning and boring holders; the clear designation CCGT060208‑MK4 WKK20S helps to match holders and tool‑post configurations.

What advantages does the Tiger‑tec Silver series provide?
The Tiger‑tec Silver technology combines coating performance with substrate toughness to extend tool life under abrasive conditions and to maintain dimensional stability in production runs.
