Product Spotlight

Benefit from the 90 degree lead angle allows efficient square shoulder milling. It uses industry standard LNKT 080404 insert which has a double positive rake angle. Precise 90 degree square shoulder and 4 cutting edges.



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

  • Fitted with 10 degree positive rectangular inserts allow high depth of cut and feed per tooth
  • 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
  • Helical versatile and ultra smooth coating technology prevent chip welding
  • Easy reference guide for insert number, screw, and other accessories is printed on the tool shank

  • Use LNKT 080404 insert (sold separately)
  • LNKT insert with high strength positive cutting edge to increase wear resistance and reduce cutting pressure
  • Setting Angle: 90 degree
