CCMT060208-FK6 WKK20S turning insert for cast iron (Tiger‑tec Silver) by Walter Tools — Rhombic 80°, 0.8 mm corner radius

The CCMT060208-FK6 WKK20S is a rhombic 80° coated carbide turning insert engineered for efficient machining of cast iron components in demanding shop-floor conditions.

• Tiger‑tec Silver coating for wear resistance
• FK6 chipbreaker for short, controlled chips
• Rhombic 80° form with 0.8 mm corner radius

Consistent wear resistance for abrasive cast iron work

The combination of the Tiger‑tec Silver coating and the WKK20S cutting grade is optimised for the abrasive nature and short, breaking chips common to cast iron. The multilayer coating increases wear resistance and reduces flank wear rates, which translates into longer tool life and fewer insert changes. For production environments that require steady mean-time-between-interventions, this grade offers a measurable improvement in process stability without sacrificing edge integrity.

Geometry tuned for repeatable accuracy and surface quality

The rhombic 80° form, together with a 7° relief angle and a 0.8 mm corner radius, provides a balance between cutting-edge strength and accessibility in tight-turning situations. The insert’s tolerance class M supports consistent seating in the toolholder, reducing variability between indexings. These geometric properties help to achieve uniform part-to-part surface finishes while maintaining dimensional control during serial turning operations.

Optimised chip control to increase productivity

The FK6 chipbreaker is specifically designed to produce short, manageable chips when machining cast iron. Improved chip control lowers the risk of chip entanglement and allows closer approach to fixtures and components, which in turn reduces secondary handling and cycle time. The coated-carbide construction supports higher cutting volumes and consistent output, contributing to greater productivity and lower per-part tooling costs over sustained production runs.

Practical application guidance and compatibility

Intended as a drilling/bore and turning indexable insert, the design supports common turning operations in workshops processing cast iron components under ISO 513 group K conditions. The insert’s sizing (plate size 06 and thickness 02) fits standard toolholders designed for CCMT-style geometry; correct seat preparation and recommended cutting data ensure best performance. When used with appropriate cutting speeds and coolant strategies for grey and nodular cast irons, the insert delivers consistent results and predictable wear behaviour.

FAQ

Which materials is this insert designed for?
The CCMT060208-FK6 WKK20S is formulated for machining cast iron (ISO group K), providing controlled wear behaviour and predictable chip formation on abrasive grey and nodular cast irons.

What benefit does the Tiger‑tec Silver coating provide?
The Tiger‑tec Silver coating increases surface hardness and heat resistance, improving wear resistance and extending insert life under typical cast iron cutting conditions.

How does the FK6 chipbreaker affect machining?
The FK6 chipbreaker produces short, controllable chips that reduce chip management issues and enable closer tool-to-fixture work, improving process reliability and safety in automated or manual turning.

What does the rhombic 80° geometry mean for operation?
The rhombic 80° form offers a compromise between strong cutting edge and access to shoulder and groove features, while the 0.8 mm corner radius enhances edge strength for interrupted cuts.

Is the insert suitable for high-production environments?
Yes; the combined coated-carbide grade and the FK6 chip control make this insert suitable for production runs where consistent tool life and low variability are priorities.
