About Charnwood VIPER3R 95mm Diameter, 4 Jaw Geared Scroll Chuck
4 Jaw Scroll Chuck with locking screws for using on a lathe with reverse direction.
The best selling size from the Charnwood Viper range. A 4″ sized scroll chuck, with the jaws adjusted by a geared mechanism for simple one handed operation. Self centring, high precision design. Ideal for Midi sized lathes and upwards. The fully enclosed design prevents the build up of chips and dust inside the gear mechanism.
The standard dovetail jaws can grip the work piece 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 M33x3.5. for all other 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, rear cover plate, wood screw, T-bar 8mm square drive for scrolling the jaws and T-handled hex key 4mm for removing the jaws.
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.

What is The difference between Viper3R and Nexus3R?
The only difference between our 2 chucks is the position of the jaw mounting holes and the pattern on the underside of the jaw. The reason we offer the 2 is to have compatibility with other brands of chucks on the market. If you are buying a second chuck, it makes sense to have one which is compatible with any jaws & accessories you already own. If it is your first chuck: it really makes no difference which model you select.

- Charnwood Viper3
- Charnwood W836 (Requires V3JS)
- Vicmark VM100 (Requires V3JS)
