We have an extensive range of optional jaws and accessories available for the Viper range of chucks.

The locking screws allow the chuck to be locked onto the lathe spindle, providing the lathe conforms to DIN800 standard or Jet Type T38 design. A 3mm Hex key is required (not included). Reverse direction should only be used when the chuck is mounted directly onto an M33 x 3.5 spindle thread. It should not be used in reverse when using a thread adapter.
