Consistent productivity for abrasive cast iron

The coated carbide grade WKK20S from the Tiger‑tec Silver series is tuned for the abrasive nature of cast iron, delivering stable chip formation and extended tool life. The combination of a wear-resistant coating and a grade formulated for short, breaking chips reduces flank wear and maintains cutting-edge integrity over longer runs. This results in fewer index changes and a steadier production rhythm, which benefits batch processes and serial turning applications.

Geometry that balances edge stability and versatility

The rhombic 80° shape with an 11° clearance angle and a 0.4 mm corner radius provides a robust cutting edge while allowing flexible approach geometries. The RK6 chipbreaker promotes controlled chip segmentation during interrupted and continuous cuts, improving surface finish and lowering the risk of chip re-cutting. Such geometry is particularly beneficial where a balance between tool life and component quality is required.

Coating and substrate engineered for longevity

The Tiger‑tec Silver coating system combines a resistant surface layer with a tough carbide substrate, creating a microstructure that resists abrasive wear typical of grey and ductile cast irons. The result is improved edge retention and consistent dimensional accuracy in turning operations. For process planners, this means predictable performance across a range of cutting conditions and fewer unexpected tool interventions.

Application-focused advantages and handling notes

Designed for machining cast iron according to ISO material group K, the insert’s chipbreaker and substrate pairing are suited to typical casting irregularities and short-chip tendencies. The insert form and size code support common toolholder platforms for easy integration into existing setups. While the insert offers good wear resistance and chip control, matching cutting parameters and coolant strategy to the specific cast iron grade will ensure optimal balance between productivity and surface integrity.
