Consistent performance on cast iron with Tiger·tec Silver

The coated Tiger·tec Silver grade WKK10S is developed for the typical abrasive wear and short, breaking chips associated with cast iron. This turning grade combines a wear-resistant coated carbide substrate with a tailored surface layer to extend tool life under intermittent contact and heavy interrupted cuts. In practice, the insert reduces the frequency of edge changes and supports predictable process windows, which helps maintain steady production throughput and lower overall machining costs.

Stable cutting geometry for improved surface quality

The Rhombic 55° form and a 1.2 mm corner radius provide a balanced combination of cutting edge strength and accessibility in shoulder and general turning operations. The MK5 chipbreaker promotes the formation of short, segmented chips that are easier to evacuate from the cutting zone, lowering the risk of surface damage and workpiece rework. A 0° negative rake enhances edge robustness in grooving and finishing cuts, delivering reliable dimensional consistency when machining intricate cast iron components.

Productivity gains through reduced downtime and repeatable results

Thanks to its focused design for K (cast iron) applications, the insert enables longer intervals between indexings and consistent cutting behaviour across batches. The coated grade supports elevated process stability and repeatable edge wear, which is particularly valuable in series production. Compatibility with standard DNMG toolholders ensures straightforward integration into existing tool setups, meaning changeover times remain short and the production flow keeps moving with minimal interruption.
