DNMG150408-MK5 WKK20S indexable turning insert — Tiger·tec Silver coating, for cast iron | Walter Tools

DNMG150408-MK5 WKK20S is an indexable turning insert designed for productive machining of cast iron components, offering a coated carbide grade tuned to resist abrasive wear and deliver consistent cutting performance.

• Tiger·tec Silver coated carbide grade WKK20S
• Optimised for cast iron machining
• MK5 chipbreaker for reliable chip control
• Rhombus 55° geometry, 0.8 mm corner radius

High-performance coating for abrasive cast-iron conditions

The combination of the Tiger·tec Silver coating and the WKK20S grade provides enhanced resistance to abrasive wear typical of cast-iron machining. The coated carbide substrate keeps the cutting edge stable under interrupted cuts and elevated temperatures, which translates into longer tool life and fewer indexings. For production environments that prioritise consistent throughput, this insert reduces unplanned downtime by maintaining cutting performance across multiple workpieces, supporting efficient batch processing and predictable machining cycles.

Precise chip control and cutting-edge geometry for better surface quality

Engineered with the MK5 chipbreaker and a rhombus 55° geometry, the insert promotes controlled chip formation and safe chip evacuation. The 0.8 mm corner radius helps to distribute cutting forces and improves edge strength, resulting in more stable cuts and a finer surface finish on the workpiece. The 0° negative rake increases robustness of the cutting edge, making the insert suitable for heavier cuts and interrupted surfaces. These features together enhance process reliability and reduce the need for secondary finishing operations.

Practical use in production: compatibility and process benefits

This indexable insert is primarily intended for cast iron applications (material group K) and integrates easily into standard toolholders that accept DNMG geometry. The combination of coated carbide and the MK5 chipbreaker supports repeatable performance in serial production, contributing to cost-efficiency through fewer tool changes and predictable tool-life cycles. As a product from Walter Tools’ Tiger·tec Silver series, it offers proven industrial quality and is suitable for workshops and production lines seeking stable, productive turning of abrasive cast-iron components.
