  • PCD Inserts of TKF type only for Turning and Grooving.
  • Cut-off is not recommended.

Note 1) The cutting edge of the TKF-AS/-ASR will be 1mm lower KTKF toolholder than the center line when attached to the KTKF toolholder (Ref. to Fig.1). Adjust the height by making NC lathe parameter settings or inserting a plate. 2) If the 1mm adjustment is not possible on your automatic Fig.1 When a TKF-AS/-ASR insert is attached lathe, use the TKF-NB. (Ref. to Fig.2.) (The cutting edge is 1mm lower than the center line.) KTKF toolholder
