CCMT060204-FK6 WKK20S turning insert – Rhombus 80° geometry, Tiger·tec Silver coating, Walter Tools

CCMT060204-FK6 WKK20S is a turning insert designed for machining cast iron with a positive geometry and abrasion-resistant coating

• Tiger·tec Silver coating for wear resistance
• WKK20S grade optimised for cast iron machining
• Rhombus 80° geometry for versatile turning
• 0.4 mm corner radius for fine surface finishes

Increased process stability through specialised coating and grade

The Tiger·tec Silver coating paired with the WKK20S carbide grade delivers a balance of abrasion resistance and toughness that is specifically tuned to the abrasive nature of cast iron. The coating reduces flank wear rates under intermittent or interrupted cuts, so tool life is extended and machining intervals are lengthened. This results in a measurable reduction in tool changes and an improvement in overall process reliability for production runs where consistent dimensional accuracy is required.

Geometry and edge design that support quality finishes

The rhombus 80° shape with a 0.4 mm corner radius provides a controlled cutting edge for finishing and semi-finishing operations on grey and nodular cast irons. The positive rake and the nominal 7° free angle produce less cutting force and promote stable, short-breaking chips typical of cast materials. As a consequence, surface quality is improved and workpiece handling can be streamlined, with fewer secondary operations needed to meet dimensional and visual tolerances.

Practical integration and workshop advantages

Supplied in the proven CCMT format, the insert is compatible with a wide range of standard indexable holders used in turning centres and lathes. The FK6 chipbreaker supports predictable chip flow when paired with appropriate feeds, helping to avoid chip entanglement and facilitating unattended machining. The robust design and standardised form factor mean that stocking and tool-change procedures are simplified, contributing to reduced setup times and a more efficient shop-floor workflow.

FAQ

What materials is this insert intended for?
The CCMT060204-FK6 WKK20S insert is intended for machining cast iron, with the WKK20S grade and Tiger·tec Silver coating optimised for abrasive cast materials.

How does the Tiger·tec Silver coating benefit production?
The Tiger·tec Silver coating on the CCMT060204-FK6 reduces abrasive wear and improves edge stability, which extends tool life and supports consistent production quality.

What is the significance of the 0.4 mm corner radius?
A 0.4 mm corner radius offers a compromise between strength and surface finish, enabling fine finishing passes while maintaining edge robustness during light interruptions.
