  • Large insert selection to machine a range of socket sizes in Hexagon, Square, and Hexalobular (6-lobe) shapes
  • Low cutting forces make this tooling ideal for machining small diameter workpieces
  • Each insert size is spec'd to machine a range of socket hole sizes

Shaper Duo Set-up Instructions (hexagon example)

① Insert Installation

  • Confirm that D-cut surface of sleeve holder is parallel to the side of the insert bar. Minimize the overhang of the insert

② Make sure the sleeve is set parallel

  • Set the sleeve into the tool post and make sure the sleeve is set parallel.
  • Minimize sleeve overhang.

③ Confirmation of height

  • Machine one feature larger than the pilot hole without chamfering
    *If the insert chips with large depth of cut, then increase the number of machining passes with smaller depths of cut.
    (Recommend: 0.025mm x 5 passes) No chamfering is required.
  • Measure the legth of both [a] and [b] with a comparator or magnifier.
  • Adjust centerline height by rotating the sleeve until you get the same length for [a] and [b]. (the difference should be less than 0.02mm)
    * If a step is still seen even after increased passes, please restart the setup process.
    Make sure both the insert and the holder are set up correctly.
