Tool_holder in tightening fixture

Torque Specifications

We recommend using a tightening fixture and torque wrench to make sure cutting tools and retention knobs are properly tightened. Over-tightening can distort or even crack collets, causing runout problems and premature failure of the collet, nut, tool holder and cutting tool. Under-tightening can also cause poor cutting performance, or allow cutting tools to fly out of the spindle – a very serious safety hazard

  • Snap collet into nut.
  • Insert cutter into collet. Collets without counter bore require shank to extend to the bottom of the collet.
  • Hand tighten collet nut assembly into tool holder.
  • Insert tool holder assembly into tightening fixture and secure it.
  • Tighten collet nut to recommended torque using a torque wrench and adapter.
