• Specifically for cast iron machining
• Round insert, size 08, D57 chipbreaker
• High process stability and consistent results

Consistent performance and extended tool life for cast iron milling

The combination of Tiger·tec Gold coating and the WKK25G grade delivers pronounced wear resistance against the abrasive nature of cast iron. The tailored coating reduces flank and crater wear, which directly extends tool life and lowers tooling costs per component. For production environments where repeatability matters, this configuration helps maintain dimensional stability and surface quality over longer tool cycles, improving overall productivity without more frequent insert changes.

Predictable chip formation reduces interruptions

The D57 chipbreaker and round insert geometry are engineered to produce short, breaking chips typical for cast iron machining. This leads to reliable chip control, fewer clogs in the toolpath and easier evacuation from the cut. Operators benefit from reduced machine stoppages and less manual intervention, especially in high-volume milling operations where consistent chip behaviour is essential for uninterrupted runs and stable cycle times.

Robust grade and edge stability for reliable machining

The WKK25G carbide grade, combined with the Tiger·tec Gold coating, supports a stable cutting edge under the shock and abrasion common when working with cast materials. Edge integrity is preserved over repeated passes, which means fewer unexpected rejections and a more predictable process window. Using inserts from a recognized tooling portfolio ensures compatibility with common toolholders and clamping systems while supporting repeatable process settings.

Application tips for efficient integration into production

Designed specifically for the machining group K, the insert is well suited for typical cast iron operations where short chips and abrasive wear dominate. The round shape allows flexibility in approach angles and can be beneficial for trochoidal or high-feed strategies where micro‑engagements and consistent cutting forces are required. When integrating the component into a tooling system, select appropriate feeds and speeds that account for the abrasive nature of cast iron to fully exploit the Tiger·tec Gold characteristics and the WKK25G grade benefits.
