Description

Key Technical Advantages

  • Balanced PM Chipbreaker: Optimized medium rake geometry provides a perfect compromise between edge toughness and light cutting performance, suitable for interrupted cuts.
  • Integrated Wiper Edge: Features a high-precision wiper geometry (Bs=1.34mm) that ensures exceptional surface finish on vertical walls and floors.
  • Stable Chip Evacuation: The optimized curved chipbreaker surface reduces friction and ensures consistent chip curling even at medium depths of cut.
  • Multi-Process Versatility: A single insert solution for 90° square shoulder milling, face milling, ramping, and 3D profiling.
  • High Process Security: Designed for stable performance in both semi-finishing and light roughing, reducing unpredictable edge failure.
