Product details

4 Jaw Scroll Chuck with locking screws for using on a lathe with reverse direction.

Based on our best selling Viper range of chucks, the Nexus3R has a jaw mounting compatible with Supernova, G3 Nova and Robert Sorby Patriot Jaws. This will be of particular interest to any owners of those chucks looking for a second chuck and wanting to be able to continue using any jaws they already own.

A 4" sized scroll chuck, with the jaws adjusted by a geared mechanism for simple one handed operation. Self centring, high precision design. The fully enclosed body of the chuck prevents dust and chips from getting inside and plugging up the teeth of the gear mechanism. Ideal for Midi sized lathes and upwards.

The standard dovetail jaws can grip the workpiece both internally or externally depending on the style and shape of the piece to be turned.
The chuck fits directly onto lathes with headstock thread size of M33 x 3.5tpi. For other thread sizes, an optional insert is required.

We also include a wood screw which clamps into the centre of the chuck for the initial mounting of bowl blanks.

Supplied with standard dovetail jaws, wood screw, T-bar for locking the jaws and T-handled hex key for swapping the jaws.

We have an extensive range of optional jaws and accessories available for the Nexus3R chuck.

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. 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.
