Features and Benefits


  • Utilizes double-sided technology with 6 cutting edges!
  • Reduces cycle time, increases productivity
  • Double-sided insert offers economical advantages when compared to competitors inserts


  • Optimized chipbreaker geometry designed for high feed machining, up to .118 inches per revolution (3mm/rev)
  • Reduced cutting forces and surprisingly smooth cutting action due to a positive, but strong, cutting edge
  • Chip thinning principle reduces depth of cut notching, prolonging tool life
  • Maximum feed rate =.118ipr , Maximum machining depth = .100"
