Applications

This turning insert is expressly designed for heavy roughing applications in various steel alloys. Its negative 80° geometry provides the necessary edge strength to handle significant depths of cut. It represents a highly practical choice for both continuous operations and scenarios involving light interrupted cuts, maintaining reliable chip evacuation throughout the entire process.

Special features

The insert features a state-of-the-art CVD coating applied over a tough two-color P20 carbide substrate. This well-matched composition ensures a high wear resistance while providing the structural integrity needed for high cutting loads. Consequently, the tool accommodates demanding tasks and maintains structural stability during general steel processing.
