CCMT120408-MK4 WKK10S turning insert – Tiger·tec Silver grade for cast iron by Walter Tools

CCMT120408-MK4 WKK10S is a versatile boring and turning indexable insert, designed for reliable performance in abrasive cast iron applications.

• Tiger·tec Silver coating for high wear resistance
• Optimised for cast iron machining
• Rhombus 80° geometry for versatile turning
• MK4 chipbreaker for consistent chip control

Durable coating that extends cutting life for abrasive materials

The Tiger·tec Silver coating delivers enhanced resistance to abrasive wear and improved thermal stability, which translates into longer tool life when working with cast iron. As a coated carbide grade, WKK10S is tailored to the typical short, brittle chips and abrasive cutting conditions of cast materials, reducing flank wear and preserving cutting-edge integrity. This results in fewer insert changes and steadier production cycles, supporting cost-effective machining without compromising component quality.

Geometry and chip management for predictable surface finish

The Rhombus 80° insert form combined with the MK4 chipbreaker ensures stable chip formation and evacuation during turning and boring operations. The edge radius 0.8 mm increases strength at the cutting edge, improving resistance to impact and helping to achieve a consistent surface finish on castings. The 7° clearance angle contributes to reduced rubbing and lower cutting temperatures, enabling controlled metal removal and repeatable dimensional results in series production.

Practical application benefits and process reliability

Classified for ISO group K, this insert is particularly suited to cast-iron machining, where abrasive wear and fragmenting chips are common. The combination of grade, coating and geometry provides a balance of wear resistance and toughness suitable for a wide range of cast materials. Using this insert supports predictable tool life and stable cutting conditions, which helps to reduce downtime and improve throughput. For integration into existing tool systems, the insert designation and form are compatible with standard CCMT toolholders for turning and boring tasks.
