DCMT11T308-FK6 WKK20S indexable turning insert – FK6 chipbreaker, Tiger‑tec Silver, for cast iron (Walter Tools)

The DCMT11T308-FK6 WKK20S is an indexable turning insert designed for machining cast iron, combining a chip‑controlling FK6 breaker with a wear‑resistant Tiger‑tec Silver coating for stable production.

• Tiger‑tec Silver coated grade WKK20S
• Optimised for cast‑iron machining
• FK6 chipbreaker for controlled chips
• Rhombic 55° with 0.8 mm corner radius

Consistent metal removal and predictable tool life for cast‑iron work

The grade WKK20S is specifically matched to the demands of cast iron machining: it is a coated carbide designed to handle abrasive wear and the short, breaking chips typical of these materials. The FK6 chipbreaker promotes controlled chip formation, reducing the risk of built‑up edge and machine interruptions. For production environments this results in more predictable tool life, fewer unscheduled stops and a steadier output quality when turning grey or nodular castings.

Durable cutting edge and process security thanks to advanced coating

Equipped with Tiger‑tec Silver technology, the insert offers a coating system that enhances thermal resistance and abrasion protection compared with uncoated grades, delivering process reliability across extended runs. The combination of coated carbide and the specified tolerance class M ensures reproducible seating and repeatable cutting performance in indexable tooling systems, which supports stable cycle times and simplified tool management on the shop floor.

Geometry that balances edge strength and surface finish

The rhombic 55° form together with a 0.8 mm corner radius and a 7° relief angle creates an insert geometry that balances robustness and finishing capability. The moderate radius increases edge strength for interrupted cuts, while the 55° orientation provides good access on facing and light turning operations. The insert thickness T3 adds mechanical rigidity to withstand typical turning forces in cast‑iron applications, helping to reduce vibration and improve surface consistency on the workpiece.

FAQ

What materials is this insert suitable for?
The DCMT11T308-FK6 WKK20S from Walter Tools is formulated primarily for cast iron applications and is optimised for the abrasive and chipping characteristics of those materials.

How does the FK6 chipbreaker benefit production?
The FK6 chipbreaker on the WKK20S insert promotes safe, short chip formation and easier evacuation, which helps maintain process stability and reduces interruptions during cast‑iron turning.

What advantages does Tiger‑tec Silver provide?
The Tiger‑tec Silver coating increases wear resistance and thermal stability of the coated carbide, supporting longer tool life and consistent cutting performance under typical turning conditions.

Is the insert suitable for interrupted cuts or heavy machining?
The combination of a 0.8 mm corner radius, T3 thickness and rhombic 55° geometry provides enhanced edge strength that is beneficial for interrupted cuts and routine turning tasks in cast‑iron components.
