  • LNKT insert with 4 cutting edges suitable for milling in steel, stainless steel, cast iron and other difficult machined materials
  • Vertical mounting of the insert changes the direction of cutting forces which is absorbed by the thick carbide insert body to increase tool rigidity
  • Vertical mounting design combined with thick carbide insert increases the potential feed rate by 30% in roughing compared to horizontal mounted insert such as APKT

  • Low runout of the square shoulder leaves good surface quality in workpiece and no obvious tool marks in the contours
  • Double positive rake angle design reduces cutting forces

  • High strength tool body material with coolant thru port on each flute

  • Easy reference guide for insert number, screw, and other accessories is printed on the tool shank



  • LNKT double side insert with 4 cutting edges to maximize cost effectiveness
  • 0.315" Maximum depth of cut 
  • 0.175" Extra thick insert body to withstand high impact cutting environment
  • High strength positive cutting edge angle for increased wear resistance and reduced cutting pressures
  • Helical cutting edge is designed to achieve smoother cutting
  • Highly versatile and ultra smooth coating technology prevents chip welding for longer tool life
  • YB9320 grade combines substrate with good toughness and strength and TiAlN nano PVD coating process to yield high strength and toughness
  • Widely applicable for semi-finish milling of P type (P10-P30) and M type (M10-M30) material
