SCMT09T308-FK6 WKK20S indexable turning insert – Tiger·tec Silver, for cast iron, Walter Tools

The SCMT09T308-FK6 WKK20S is a square indexable turning insert designed for efficient machining of cast iron components, combining a robust coated-carbide grade with a chipbreaker tuned for short, brittle chips.

• Tiger·tec Silver coating for extended tool life
• Optimised for cast iron machining (ISO group K)
• FK6 chipbreaker for controlled chip formation
• Square 90° insert with 0.8 mm corner radius

Higher throughput with predictable tool life

The coated-carbide WKK20S grade from the Tiger·tec Silver family is engineered to resist the abrasive wear typical of cast iron machining. The combination of a wear-resistant coating and a tough substrate means fewer interruptions for tool changes and more consistent component quality, which translates into measurable production gains. The insert’s economy becomes apparent over multi-shift runs where tool life stability reduces scrap and rework, supporting a more efficient machining cycle.

Secure chip control and stable cutting performance

A dedicated FK6 chipbreaker and the square 90° geometry provide controlled chip formation and evacuation when machining grey or ductile cast iron. The 0.8 mm corner radius softens the cutting edge load, improving edge strength without compromising dimensional stability. The 7° clearance angle supports smooth entry and exit of the insert, reducing vibration and improving surface integrity. These features together deliver reliable cutting behaviour, simplifying process parameter selection and reducing the need for frequent adjustments.

Seamless integration and dependable manufacturing support

The insert is produced to a tolerance class M and a plate thickness code T3, with the standard 09 size format for broad compatibility with common toolholders. As a square insert, it offers four usable cutting edges, enhancing cost-efficiency per indexation compared with single-edge alternatives. The coated carbide composition and chipbreaker design make the insert particularly suitable for abrasive cast iron alloys (ISO group K), ensuring repeatable results in serial production and repair tasks.
