CCMT060204-MK4 WKK20S – turning and boring indexable insert, Tiger·tec Silver, for cast iron (Walter Tools)

The CCMT060204-MK4 WKK20S is a coated carbide indexable insert engineered for productive turning and boring in abrasive cast-iron applications, combining a robust chipbreaker and an 80° rhombic geometry for versatile toolpaths.

• Tiger·tec Silver coating for extended tool life
• MK4 chipbreaker optimised for cast iron machining
• Rhombic 80° form for versatile turning and boring
• 0.4 mm corner radius for consistent surface quality

Maximise productivity with a coating tuned to cast iron

The coated carbide grade, based on Tiger·tec Silver technology, is formulated to resist the abrasive wear typical of cast-iron workpieces. This results in stable tool life and fewer insert changes during production runs, which improves overall process efficiency. The insert’s coating and substrate pairing are particularly effective where chopped, breaking chips are generated; the result is more predictable machining cycles and reduced unscheduled downtime.

Chip control and geometry for reliable machining

Equipped with the MK4 chipbreaker, the insert provides controlled chip formation and evacuation in interrupted and continuous cuts typical of cast-iron components. The rhombic 80° shape offers a favourable approach angle for general turning and boring, while the 0.4 mm corner radius supports repeatable surface finish without compromising strength at the cutting edge. These design elements together improve dimensional stability and reduce the need for finishing passes.

Industrial suitability and process advantages

Classified for ISO group K (cast iron), the insert is engineered to perform under the specific demands of abrasive, brittle materials, offering reliable edge security and consistent cutting behaviour. The M tolerance class and the insert dimensions ensure compatibility with common toolholders and turning systems used in CNC lathes and boring heads, enabling rapid changeover and straightforward tool management in high-mix or high-volume environments.

Application focus and operator benefits

In production settings where throughput and repeatability matter, the insert supports shorter cycle times and reproducible part quality. The combination of advanced coating technology and a dedicated chipbreaker reduces edge wear and improves surface integrity, which helps meet quality targets with fewer corrective steps. For shops machining cast-iron parts, the insert is a practical choice for maintaining productivity while controlling scrap rates.
