To satisfy the need for ultimate perfomance a closed-center chuck variant has been designed, based on the proven QLC type of chuck. Combining the patented QLC jaw guidings with the rugged and precise elements of the KT type of chucks, lead to a chuck design ideal for heaviest-duty machining. The KTN / KTG chucks are designed to enable enormous clamping forces with consistently high repeatability and precison.

Technical Features:
  • Maximum gripping force
  • Maximum speeds
  • Quick-change jaw system (easily to be automated)
  • Power chuck for quick change of jaws
