K55-IV Series Wedge Type High-Speed Power Chucks With BIG Through Hole

wtpc-k55iv.JPG (8918 bytes)
  Besides having all the features of K55 series chucks, these chucks are distinguished for their bigger through-holes, which makes them especially good for rod material's processing.

  Equipping all kinds of full-function CNC lathes with these chucks makes it possible to make the most of the lathes.
