Description

Key Technical Advantages

  • Steel-Optimized PL Geometry: Specifically developed for medium to heavy roughing of steel components, balancing edge strength with high metal removal rates.
  • Impact-Resistant Edge: The reinforced PL chipbreaker is designed to handle high cutting depths and feed rates, providing superior resistance to thermal and mechanical shock.
  • 1.74mm Wiper Performance: Features an integrated precision wiper flat (Bs) that smoothens the workpiece surface, reducing the need for secondary finishing operations.
  • Smooth Chip Evacuation: The enlarged chip gullet geometry prevents chip jamming during high-volume milling, ensuring process stability in continuous operations.
  • Precision 90° Verticality: Designed for standard 90-degree cutters to achieve excellent squareness on steps and faces, maintaining high dimensional accuracy.
