DCMT11T304-FK6 WKK20S indexable turning insert — Tiger·tec Silver grade for cast iron, Walter Tools

The DCMT11T304-FK6 WKK20S is a rhombic 55° indexable turning insert engineered for efficient and repeatable machining of cast iron components.

• Tiger·tec Silver coated grade WKK20S
• Optimised for cast iron (ISO group K)
• FK6 chipbreaker for controlled chips
• Rhombic 55° form with 0.4 mm nose radius

High abrasion resistance for consistent productivity

The coated carbide grade WKK20S from the Tiger·tec Silver family is formulated to resist the abrasive wear typical of cast iron machining. This results in a stable cutting edge and prolonged tool life when facing the short, brittle chips that cast materials generate. Thanks to the dedicated material focus (ISO group K), the insert supports more consistent cycle times and reduces unexpected rework, helping maintain throughput in serial production and maintenance tasks.

Improved chip control reduces interruptions

The FK6 chipbreaker is designed to shape and break chips reliably when cutting cast iron, lowering the risk of entanglement and tool damage. Controlled chip formation improves process security on lathes and turning centres and minimises manual clearing interventions. A well-managed chip flow also contributes to a steadier surface finish and fewer machine stops, which supports higher overall equipment effectiveness in daily operations.

Geometry tailored for versatile turning operations

The rhombic 55° geometry with a 0.4 mm nose radius and 7° relief angle offers a balance between cutting strength and access to varying part profiles. This geometry is suitable for both light finishing cuts and more robust profiling where a compact entry angle is beneficial. The T3 thickness and the M tolerance class ensure dependable seating and repeatable indexing in standard toolholders, aiding quick tool changes and stable cutting conditions.

Application support and practical use cases

Primarily intended for cast iron turning, this insert performs well in medium to high material removal scenarios where abrasion resistance and chip control are priorities. When paired with appropriate holder geometry and rigid setup, the combination of Tiger·tec Silver coating and FK6 chipbreaker supports productive machining of brake discs, housings and similar grey or nodular cast-iron components. For tailored cutting parameters and process optimisation, Metav Werkzeuge provides consulting to match feed, speed and depth of cut to specific machines and setups.

FAQ

What materials is this insert suited for?
The DCMT11T304-FK6 WKK20S is designed primarily for cast iron applications (ISO group K) and performs best where abrasive wear and short, breaking chips are expected.

How does the Tiger·tec Silver grade benefit machining?
The Tiger·tec Silver coating on the WKK20S grade improves abrasion resistance and cutting-edge stability, leading to longer tool life and more consistent component quality in cast iron turning.

What advantage does the FK6 chipbreaker provide?
The FK6 chipbreaker promotes controlled chip formation and breaking when machining cast iron, reducing downtime for chip removal and improving process reliability.

Is the rhombic 55° form suitable for profiling?
Yes, the rhombic 55° geometry with a 0.4 mm nose radius offers a versatile compromise between accessibility for profiling and the cutting strength required for stable turning.
