  • Semi-steel chuck body made from high quality cast iron

  • Four operating screw design with each ground and hardened to HRC 43
  • Both side of jaw teeth and guides are ground and hardened to HRC 58-62

  • Four jaws allow a square component to be perfectly centered to the chuck while achieving maximum gripping force
  • Each set of jaws are serialized in their own set
  • A serialized set of jaws are then finished, ground, and lapped on their designated chuck body which will be the same chuck body on the final assembly to achieve a greater accuracy

  • Before assembling the jaw to its designated chuck body, the jaw's finish machining are performed on a closed tolerance state of the art CNC machine from Japan
