  • shars cat40 ER tool holder

    Mirror Finished

    Taper ground to AT3 or better specification ensures 80% or more contact with spindle to reduce harmonics and improve runout tolerance

  • shars cat40 tool holder

    Pilot Contact

    Inside bore are precision ground to engage a better contact with indexable cutter's pilot to increase rigidity

  • This tool holder accepts all threaded screw-in indexable mililng cutter which are often called modular indexable tooling, screw in or threaded shank cutter
  • Precision ground flat on the shoulder and internal pilot diameter that will self center the threaded indexable cutter
  • By accepting right-hand thread cutter into the tool holder, apply cutting force onto the cutter would increase the bond between the cutter and the tool holder
  • Runout is less than .0001" from taper to pilot bore
  • Made from alloy steel hardened to 54-60 HRc

  • Modular milling cutter head is able to cover variety of milling operation in die and mold manufacturing, automobile manufacturing, energy and wind power, and aerospace industry
  • Reduce inventory by only replacing cutter heads and not shank, other style of cutter body with different insert is also available
  • Feature precision ground surface on the locating shoulder and pilot outside diameter to ensure rigid contact with the threaded tool holder

  • Indexable cutter head threads into the tool holder by means of a right hand thread, any cutting force would only increase the bond between tool holder and cutter head
  • Reduces vibration on long overhang applications
  • Chip thinning effect allows for increased table feeds
  • High Positive cutting geometry 
  • Fitted with 10 degree positive rectangular inserts allow high depth of cut and feed per tooth
  • Use APKT / APHT / APET / APMT 11T308 insert (sold separately)
  • Setting Angle: 90 degree
  • Radial rake angle: -10 degree
  • Axial rake angle: 7 degree
