All accessory jaws in the Standard Chuck range will fit all the Standard NOVA (NOVA Infinity Quick Change requires optional accessory Upgrade Kit or Retro Fit Kit to attach standard NOVA Accessories). However, some jaws are not recommended for use on some NOVA Chucks due to sizing. See manual for recommendations.
